Where'd you get the other ecu? Out of the gold one? I guess it's possible that both ecu's have the same exact intermittent problems happen at the exact same time I mean seriously though, since you've used both ecu's and gotten mixed results I wouldn't point the finger in the same direction as Haynes would The simplest solution I can come up with is that either the ground for the ecu is breaking somewhere near or at it's mounting location or that the ECU wiring connector has some bad wiring somewhere at the connector. I'm gonna find that grounding spot tomorrow (unless someone already knows where it is) and then you can check that. If it's not the grounds then atleast you'll have narrowed it down even further. Not much left after that though other than a bad connection at the ECU.

Uhhh, Just a thought here guys, but why don't you use AIM or some other Instant Messenger program... not that I would want J's post count to suffer or anything. Seriously though, it seems like it would make this whole process alot easier on you both.

Bastard, there goes my chance for the guiness book on post counts . That's a good idea. I don't belong to any of those though. You black. If you've already got something then I can sign up for one. I've got a hotmail account so I can do msn. And I'm using AOL right now so I can do AIM too.

81 Black L28E

it turned over like it was going to start this moring then the tach droped and now it's just crnking over like it aways does i am so sick of it ...well changing the alt didnt work ....j i need to know where that ground is....also witch wire do i check on the igition

81 Black L28E

well i went down to the parts store ...i bought the back of the key switch the part that plugs into the connector and then pluggs into the key ....it didnt fix the problem

81 Black L28E

went and bought the efi relay ...the one by the battery ....$30 more dallors and it still wont start so with the key switch ...relay..and battery charger ...iam out $110 and it still wont start ...... anyone have any ideas that will cost alot of money and wont fix my problem

i think i will wast more money on this its my same part # A11-620 600

http://cgi.ebay.com/ebaymotors/ws/eB...RK%3AMEWA%3AIT


i didnt do any thing just charged the batt and then put the batt in and turned the key it started run up... i can here it running right now ..i order this ECU just to have a extra ..... mabe this ecu is fautly

NismoPick

uck! $60! I guess it's worth 60 if ya don't have access to a junk / wrecking yard. Most wrecking yards will sell ECU's for cheaper than 60 bones, and usually have some kind of waranty.

81 Black L28E

iam standing there watching run ...i just turned off ...i dont get IT ....ITS GOT TO BE THE ECU .....

81 Black L28E

Weel Ateast I Know That The Key Switch And Relay Are Golden ...it Still Wont Start ....i Unplugged The Batttery ...iam Going To Plug It Back In And See If Resetting The Ecu Works To Make It Run Again .......

81 Black L28E

OK I PUT THE BATTERY CABLES BACK ON AND TURNED THE KEY AND IT STARTED RIGHT UP..... I THINK IT HAVE NARROWED THE PROBLEM DOWN ......THE ECU HAS TO BE FAULTY ....THE WAY IT DOES IT ON TIME ONLY SHUTING IT OFF DURING WARM UP AND THEN WHEN THE BATTERY HAS BEEN REMOVED IT ALL OF A SUDDEN IT WORKS FINE ....IT ALL LEADS ME TO BELEAVE THAT THE ECU HAS SOME SORT OF PROBLEM ...
I MEAN I HAVE CHANGED EVERYTHING ...TODAY I WAS VERY CAREFUL IN EVERYTHING I DID ..ONCE I TRYED SOMETHING, I TRYED THE KEY IF IT DIDN'T WORK I WOULD MOVE ON ......THE FACT THAT IT DID IT ON TIME FOR WEEKS JUST MAKES ME THINK IT'S THE ECU EVEN MORE ....ALSO IT WILL WORK FINE ALL DAY LONG THEN THE NEXT MORING DO THE SAMETHING ...WELL INTELL I GET THIS NEW ECU I DONT KNOW WHAT TO CHECK..........J ..........Bleach ...............you got any ideas ..... .

IWW you havent said much ...WHAT!!!.... now that your Admin you to good to help OUT

THIS IS WHAT I WANT TO DO WITH IWW ZX now that the.... Zgoverment has moved him up to superstar stats ............

How about those battery cables? Did you replace those?
I've got this complete 1983 FI wiring harness that I've had for sale for a while with nobody interested. I would be willing to donate this to your cause. The only place to splice it in would be the main power wire by the battery where it enters the fender to go to the fuse panel.

Battery cables???

81 Black L28E

what about my battery cables ??????????? there the sameones i had befor ....

Bleach

Have you replaced them since you've owned the car? How new are they? They could be losing connection, causing a voltage drop in the system so the ECU shuts off??? Just a guess anyway

RodMoyes

I hate to rain on your parade Black, but the fact that it has done it with two different ECU's in the car makes me think it's not the ECU itself. What are the chances both ECU's have exactly the same fault and/or sypmtoms? What is more likely, is that both ECU's for some reason are getting a signal (or lack of a signal) that is "telling" them to shut off.

It always helps to go through and read the entire thread before you post Russ... That way you don't look foolish when you suggest doing something that's already been addressed. But, It is a forum and input is what makes it work, so "Props" for trying.

81 Black L28E

well i dont know what to think ...i know that this moring it acted like it was going to start and then the tach started jumpin up and down then nothing ...so i did the battery thing and still nothing .....i dont know what to check any more ...i have swaped in and out so many thing that i dont know .....afm ....BLEACH SEND IT TO ME ...... AND A THROTTLE POSTIONING SENSOR .......MABE THAT WILL FIX IT OTHER THAN THAT I HAVE KNOW CLUE .......TELL ME WITCH WIRES WILL SHUT THE ECU DOWN AND I WILL CHECK THEM ......IAM SO SICK OF IT ...I THOUGHT MAYBE ..JUST MAYBE I WOULD HAVE MY OWN CAR ON MY BRITHDAY IT'S NEVER HAPPENED BEFOR
SO WHY SHOULD IT HAPPEN NOW ......

RodMoyes

Patience Grasshopper,

The best thing to do is first rule out all of the things that it can't be. It can't be the TPS, It can't be the IM, etc... take a couple deep breaths and go through in your mind all of the things that you know it can't be and you'll have a good idea where to go from there. Patience.

well it started to start i could see the tach moveing and i heard a sound from up front
......it was my HARMONIC BALNACER ...it broke ....i had been hearing a sound coming from up there for a long time ...it was a clicking sound....i thought it was my timeing cain but i was wrong .... happy birthday to me


does any one have one of these laying around that they will give up for cheap

NismoPick

81 Black L28E

mabe it came lose over time i have had it off three times sence i got the car .....
mabe last time i didnt get it tight ....i put the bolt back in to see if it messed the threds up..... it didn't but there is a lot of play ,like it could have just wiggle free

i will also need the crank tooth it sits in the end of the crank and keeps the HARMONIC BALNACER in place ...........mine is gone ...its is no where to be found what if it flew into the oil pan i dought it but what if ......

81 Black L28E

looks like msa has a crank pully key and they want .81 cents for it ...the pully how ever is going to cost $148.00 come on someone out there has to have these parts ...pm ME if you can help out .....dam it i want to drive my car so bad ....today is the frist day it rained in along long time ....it would have been drifting madness
