Help! Died and won't start - Shifting cable? Neutral start switch? ENGINE CONTROL UNIT!!!

Red91Laser · Jan 15, 2020

Hi,
First let me say that though I've done some maintenance and replaced a few things over the years (in other vehicles), I am definitely not a mechanic, so any helpful advice anyone can give me will be greatly appreciated. Okay. Here's what happened:

I got in my '91 Laser (auto, 1.8L, no mods), turned the key and it started right up then almost immediately died and an acrid smell (burning insulation?) filled the cab. Everything seemed to still work - all the accessories, the starter turned the motor - but no running. I checked the gear selector and "what do you know" I couldn't move it. With the key locked the shifter button won't depress, but will with the key in acc. position. With my foot on the brake I still cannot move the shift lever.

I'm thinking my shifting cable broke (I haven't taken anything apart yet), but what about the smell? Or is it that my neutral start switch shorted-out - but shouldn't I be able to move the selector if it were just the switch? Am I off base here?

Please let me know what you think, and if you have any advice on where to go for any parts I might need, please, don't be shy. This is the only working vehicle we have, so I need to get it back on the road.

Thanks!

Okay...I'm an idiot. I must've been REALLY stressed yesterday when the car broke. I went out tonight (I spent all day reading about the shift cables and looking for one [found one on ebay - didn't buy it]) and tried the test procedures for the key lock cable and the shift lock cable and everything went fine. The shifter unlocked and moved normally. Like I said, I'm an idiot.

By the way, here's an important post from another site about shifter cables and brackets

Code:

Code:

Anyway, even after twenty-four hours, when I got into the car I could still smell that acrid smell, and it seemed to come from the center console or near there. Imagine my surprise (not really) when I read that the ecm is located under the center console. Right now it's dark, cold, and my garage is so full of junk that I really need to roll the car outside so I can have some room to crawl under the dash, so when I can, I'll hook my meter up to the diagnostic plug and I fully expect to see the needle peg-out and stay there. Soooo, time to begin the hunt for an ecm. Wish me luck. I'll let you know what happens (if indeed you're out there). Seems the least I can do.

Well, I found a bunch of electronic control units on ebay - huge price variations. I found one for just over twohundred, a Cardone - anyone know anything about them? Strangely, the california ones are cheaper. Too bad mine isn't. I got the correct one for my car from this post:

Code:

https://www.dsmtuners.com/threads/ecu-questions.522580/

I'll order it as soon as I'm sure.

I tried the test procedure today and at first I got the expected steady 12v (it was actually only 10-11v), but then I didn't get anything (huh?). Anyway, I went ahead and bought the new (remanufactured) ecu, but I won't get it FOR A WEEK!
(sigh)
I'll let you know how it goes.

Red91Laser · Jan 19, 2020

Great news! I got the new ecu today. It seems they sent it two day priority. The bad news is that it doesn't work

.

I know I shouldn't complain about how hard it was to get in, but it was a bitch! They left almost zero slack in the looms that connect to it.

I think they (Cardone) mislabled it. They remove/deface all the original stickers on the casing, but I could still read the one with the last four digits in bold type and it wasn't what it should have been. I know they could have reprogrammed another type to make it compatible, but the fact remains, it doesn't work. It starts right up, but it won't idle (dies right away) and it misses like crazy while I'm keeping it alive, and the "check engine" light is on (never was before).

Okay, one final rant - Haynes...I used to really love Haynes manuals, but this one just kinda sucks. Not only does it leave a lot out (brakes for instance), but it's just not as complete as it used to be for the things it does cover. This time it told me I had to remove the gear shift (automatic). It told me to remove the screws and pull it off. Not only did I not have to remove the gearshift at all, but it left out the OD button entirely. I could go on, but I won't.

Now I'm not sure what to do. Cardone's pitch sounded good - complete re-soldering, each unit tested - but IT DOESN'T WORK! I don't know, should I try another Cardone (expensive), try a refirbished one from ****** (a salvage yard owner in Spokane)(less expensive), or go with a "live" used one (cheapest).
(sigh)
I'll be back.

Well, I guess I should update...
I went ahead and ordered one from ******'s. It came in today and it was someone else's order for a Honda. ******'s was a bit put-out at first (they must get a lot of bad returns or something), but after a careful reading of my return, and perhaps a corresponding return from the guy who got my ECU, they were very apologetic. Man! This is taking way too long!
I discovered that you get a much better search return on ebay if you just search the model number, in my case md159561. I got a lot more results for rebuilt units from a variety of rebuilders. I decided to go with facr_inc, whose real name is Foreign Auto Computer Repair, Inc. located somewhere in Texas. I liked what they had to say about themselves. They've been in business for over twenty years rebuilding modules, and apparently started-out doing mitsubishi modules. They claim that the mitsubishi modules up to '94 used a kind of capacitor that leaks over time and corrodes the boards, so they replace all of these, removing the problem of early failures. They also do repairs if you send yours in, promising a one day turn-around. They have a five year guarantee. I don't know if they do mods or anything, but I wouldn't be surprised. My "new" ecu will run me about $275.00 with tax, about the same as the cardone one I bought.
Wish me luck.
Chris

I don't know if the ECU is your problem but if you want to go that route first; you can buy a DSM/ Eclipse capacitor kit for very little money on eBay and have someone replace your capacitors. I did that on my 91 Eclipse 1.8 and it did the trick for me. the smell you described is textbook capacitor blowout. Some say it smells fishy (but it's not good).
You already beat the 2.0 interference valve problem by owning the 1.8. There are few capacitor replacement write-ups on the forums

Red91Laser · Jan 28, 2020

@doublesharp
Thanks for the reply. If you had gotten to me earlier I might've gone that route. I had no idea there were capacitor kits available anywhere, let alone ebay. That said, I have to admit to being utterly (and I mean utterly) ignorant of electronics. I could probably solder connections at an acceptable level, but I don't even know how to recognize a capacitor. Yeah, I'm sure it's the ECU. My car ran almost perfectly before its sudden demise; it never threw a code. The ECU was my first thought when I smelled that stench coming out from my center console. It was only the ascendancy of my "lizard brain" that got me thinking it was anything else (truthfully, I think I was pressing the OD button in an effort to unlock the gear shift, lol).

Well, I got my ECU from Foreign Auto Computer Repair today and put it in. I'm not sure.

I haven't taken it out on the road yet - just idled it in the garage for a few minutes. It's dark and raining, and I'd rather walk home in the daylight if I have to, so I'll wait until tomorrow to "run it in". It's idling without stalling - an improvement over the Cardone one, but it's running rough - missing some. It's been more than a few years since I've had to install a new ECM in a vehicle, so my memory is more than a little fuzzy. I know they need to "adjust themselves" to their new environment, but I can't recall whether there was this much missing involved.

It's true, I got a five year warranty on this unit from Foreign Auto Computer Repair, but it turns out there are exclusions:
"All sales are final. No returns, No refunds."
"We guarantee our parts/repairs to be in full function."
"We do not guarantee that it will fix your vehicles (sic) problem, misdiagnosis is unfortunately common."
"Misdiagnosis is liability of purchaser, as is Reflash/Reprogramming, which must be done when needed by qualified tech with part installed."
"WARRANTY VOID is (sic) SEAL BROKEN, or if failure is due to other parts, such as IAC mtr. failure, any electrical short, ect (sic)..."

So, perhaps the warranty really isn't worth much. If there's a problem with their unit, all they have to do is claim it's really a problem with my car. Time will tell, I guess. I really can't afford to be throwing so much money at this without actually fixing anything. As an additional kick in the pants, I have to return my original ECU as a core or they VOID THE WARRANTY. I'll have to go out and buy another one if I decide I want one to rebuild on my own (assuming it's just capacitors, that is).

Thanks for reading another chapter in the ongoing saga of the Hunt for an ECU. If everything evens-out after I drive it a bit (in other words, if I'm finally quit of this problem), I'll stop by and let you know.

Red91Laser · Jan 29, 2020

Well, I ran it around the block today and it didn't get any better - probably got a bit worse. It did, however, finally throw a code, a 41, injector. So, I need to go buy a test light, since I don't have one, so I can justify sending the ECU back - since it obviously doesn't work right.
(sigh)
Chris

Red91Laser · Jan 30, 2020

I wasn't able to get out to buy a test light today, but I did buy a used ECU from a wrecking yard on Ebay. It's from an Eclipse that looks to be in very fine shape, except for some lower body rust (it's in Wisconsin) - there are pictures. Hopefully, it still works and I can use it to verify that my car still runs as well as it did before the ECU died. I realize I'm buying the same problem that caused mine to go (old, potentially leaky capacitors), but if it works I'll have a back-up and, if I'm feeling especially self-confident, an extra (assuming I can get a good one from Foreign Auto Computer Repair) unit I can replace the capacitors in myself. The car it came out of had just over 200k miles on it. Mine has about 175k. It was about $38.00 with tax.

I feel good about this, even though it seems like I'm just throwing money I don't have at it.

Fingers crossed.
Chris

I'm Sorry that I didn't see your post sooner. Don't worry that you aren't familiar with capacitors and such I'll bet you can find a friend who knows someone or who, themself , knows how to replace them. ( I found a friend who did it for free), you might be suprised how many people do this stuff for fun.
I just did a quick eBay search for "dsm ecu capacitor kit" and this is the first one I found for your year and model. There may be better choices (this was just an example)

Make sure to do a search for capacitors on the forum search option and then whittle it down to 1g write-ups . Google and Youtube will surely help you with info. It is amazing how much these cars have their own personalities. If your car has a problem; it's almost certain you will find help out there from someone who has been there.
I hope all the best for you.

Okaaay...I checked the voltage on my injector harness and they all get 12v from the battery on the hot side, but when I checked the ground side with a test light and the engine running number three wasn't firing. There's my miss and loss of power. I also checked the resistance on the injectors and they all checked out.

The thought of trying to find and measure continuity between my number three injector plug and the ECU plug leaves me feeling exhausted and cross-eyed, so I'm going to wait until my used ECU arrives and stick it in and see what happens.

I bought one of those ECU rebuild kits (I don't have it yet), and I opened-up my old ECU - it was pretty burned-up inside in two or three places (one pretty badly), but strangely, the capacitors looked fine, except that one had a burn on its side that appeared to have come from an adjacent melt-down of another component (no idea what - resisters maybe?). The kit was the only one on ebay for 1g dsms. It only has three capacitors, but my board had an additional smaller one. I don't really know what to do about that. I suppose I should figure out how to replace it, too. I miss the days when there was a Radio Shack in every neighborhood.

The PLAN is that the used ECU will work just fine, so I can replace the old caps and finally get my wife to her doctor appointments. Going to the store whenever I want will be an added bonus. I've been using my wife's home-health aide to go shopping.

I don't know what will happen with the Foreign Auto Computer Repair ECU. If it proves to be bad I will return it. Ebay's return policy on defective merchandise is pretty hard and fast, so despite FACR's declarations to the contrary, I don't think they'll have any choice but to refund my money. It's too bad, really. I wanted an ECU I could rely on, and I really hoped I had found one, but I won't mind saving two-hundred dollars if it comes to relying on my "rebuild". The only thing I worry about is that ebay will think I'm causing trouble or trying to game the system somehow. If I have to return it, this will be my third ECU return, and my fourth return, total, in the last couple of months. Just bad luck, I guess.

When I get the used one I'm going to open it up first and have a look around before I put it in.

Wish me luck, think good thoughts, and I'll get back when something happens (suggestions, helpful hints, and moral support are always welcome).

Hurray!!! I got my latest ECU from Norb's Auto Salvage in Denmark, Wisconsin (from ebay) today. I slipped it in, turned the key, and voila, just like new. Just to be certain I checked the no. 3 injector and it was indeed firing. As an added bonus, the guy who owned the eclipse this was pulled from had had it rebuilt. It had a shiny new sticker from Norb's over the edge of the casing, but it also had two thin gold stickers, worn with time, warning of the loss of warranty should they be cut. I guess I won't be needing that rebuild kit after all. I wanted to open it up to inspect it, but since I couldn't I gave it a good strong sniff and it smelled completely clean - no smell at all

.

Just in case anyone out there has a comparable 1g with gray cloth interior and needs something (this is a GS), there are pictures of the vehicle.

Ebay accepted my return immediately (presented a return shipping label). Hopefully a refund will be forthcoming.

I want to thank everyone who's been following this in the background, assuming you were waiting until needed to jump in with wise counsel, and especially I want to thank doublesharp, who did take the time to offer some helpful advice, and let me know I was not alone (not withstanding the "eye-count" on this thread). Unless Foreign Auto Computer stiffs me (which I don't think will happen), this is "So long". See you all next time.
[Whew! Twenty days!!]
