My car been acting up for a while now. Whenever it would drop down into a higher gear it would miss i think, felt like a hiccup. Whenever there was more weigh into the car it would be worse. Well, today I was driving and the car just died and now wont start. I replaced the coil and the ignition module tested good.

3 months ago my wiring harness melted to my exhaust, I fixed all them.
Timing was right on the money.
Fuel filter replaced maybe year ago.
I have fuel pressure.

Any help would be nice ty

 

I was thinking it was the ECU because the wire that comes from the ECU to the fuel pump relay not energizing the fuel pump so I wired the relay to ignition, this happened maybe 6 months ago. Ecu maybe?

 

What codes is she throwing? Check engine codes..

 

I'll check tomorrow morning.

 

I just getting code 33. MAF no the problem. I'm thinking there a short some where from the ecu to ignition module.

 

What is your car by the way? Im just seeing the 82 V8 in your sig.

 

1989 Camaro 2.8. It will just keep cranking but will not fire. I have fuel pressure and you can hear the fuel pump kick on.

 

is the security light on ?

ur vats system may have gone active, if it did its a very simple fix.though since u mentioned the car died while running thats prolly not it.

when u crank the engine does it have spark?does the tach in the dash move while the engine is cranking ?

 

Ignition Control Module??

 

I already have the vats bypass with some resistors in series. i got the Ignition Control Module tested. I'll try and jump it tomorrow and see if the tach is moving but i'm 75% sure it is. I know the coil is getting a spark when I unhooked the coil spark plug wire it was arcing over to the bracket.

 

Alright. The tack moves to about 400-650 rpm when cranking. I checked the pick-up coil and it was reading no resistance so I replaced it, still doesnt start.

 

try sporaying some starting fluid in the throttle body and see if it tries to start

 

does the 89 have the fuse in the engine compartment by the battery like my 87 does.. I know if that fuse is blown it gives power to the ECM.. I use that as a way to disable my car so the wife can't drive it.. It is attached to the inner fender almost behind the battery if yous has that.

 

Sorry, it been a while. I threw a rod thro my oil pan in my 82 camaro. I now need this car running. After replace the pick up coil, i thought it wont start. I checked all power to ECU to fuel injector, also check all the wires to the ECU. After all that I FINNALLY got it to start but barely. I cant unhook the tan/black wire to set the timing on the car it just falls over and dies and wont start untill i plug it in. Any clues? Car runs good at 20 degree with computer in.

 

if it wont run with the est wire unhooked it sounds like the timing is way off, when u plug that wire in it advances the timing, unplug the est wire and check the timming with a timming light to verify were it is with the est wire unhooked

 

I just went out and tried again. I can get it to start but then once i unplugged the bypass it just shuts off. With the bypass i get about 25 degrees btdc timing. I'm going to pull a plug tomorrow and re time it.

 

Alright. I think the pick up coil was bad. I can now get the car to idle but whenever I give it throttle it just back fire. the timing at 10 degree with bypass unplugged whenever i plug bypass in it will die or not start. any ideas?

 

Took the ignition module and got it tested. It failed. Bought a new one, still doing it. If you give it any throttle it will back fire.

 

Okay, I forgot got to put the snap ring on that holds the pick up coil down. Its a little loose you can move it around up and down. Would this cause all the back firing?? I'm going to fix it tonight.

 

it could reasemble it unhook the est bypass and set timing to 10* and see what happens , if its still backfiring u may have 2 plug wires crossed up, or u have a plug wire arcing from one wire to another.

btw is it backfiring out the ex system or the intake manifold


ex = late timing or rich
intake = really early spark or really lean

 

When I get home here in a couple hours. I'll try and fix everything up and report back.

 

When I took the distributor out to replace the pick up coil. When I was trying to pull the shaft out " i think" I moved maybe the magnetic points thing. I said **** and spent 130 bucks on a new distributor and it fired right up. The car drives way different and a lot smother. I think this been going out for 3 months or so. Thanks for the helping guys. Now time to put a sbc 350 in my 82 camaro after throwing a rod thro the oil pan.
