Car died, pulled off, could not restart, pul ECM fuse to reset just incase, cus car would not start, plug back in, hear fuel pump, and then smoke comes rolling from the coil. Get a ride home, get my after market GM blaster, plug it in and try to start, no spark

And i jsut replaced the rotor cus studs striped and front right wheel would not stay on, well lugs woundnt, wow my day has sucked

 

sounds like your having a really bad day man ..sorry to hear that ......did you ever get the spark figured out ?

 

just happend 2hrs ago =[ dont know aobut spark, pretty sure i dont have spark, didnt really feel like getting shocked my self, having the car towed tomarrow morning

 

coil smokage prolly damaged the ICM (or the ICM fried the coil) ... hopefully nothing seriously wrong went down and the ECU is still okay. Major diagnostics time.

 

yeah doesnt sound to good

 

ECU damage

well just got the tow truck called, 45 + 2.50 per mile gota go 3-7miles, going to a trusted mechanic, he said sure i can fix that cant wait to hear how much, wonder how close im getting to just drop in a new motor, or getting a new car, any one know any really good condition LT1 F-bodies for sale around KC

 

overdraw in coil will also hit the ignition modulator. That goes and no spark as well. The modulator was put in place from the old HEI systems to help protect the ECM from feed back.

If you can get ahold of a 90-92 3.1 harness, I have a map sensor and good ECM that I could get ya.

 

Car should be in the shop getting diagnosed now, im giong to see how much they quote me at, cus i kind of need the car for work tomarrow, so its got to get fixed asap.

 

Just nit-picking, but it's an ignition module, not a "modulator"...

 

According to M-O-D it is a modulator. but since were all americans we go with module.


Question. Why would one pull the ecm fuse when the car died?

 

Well its the ignition Modulator, 265 total, and hopefully car will be done in another 1-2 hrs

things like this just make me want to drop in my 350 with a built 700R4 more and more
Too bad its sitting in my truck/Street rod Project

 

Last time my ignition module fried I spent 30 bucks and swapped it in a parking lot in about 10 minutes with no prior experience replacing an ignition module.... seriously man, time to start doing your own work

 

But the 350 has the same ignition system. So the problem would have been the same.

 

Sorry to hear about your car man, but were you the one in the other thread talking about holding the throttle wot for like 2 seconds to listen to the motor scream?

 

lol must be ignition related and not valve float related

i still have 205XXX miles on my car, and its about time some stuff starts to fail, motor goes, new car, or new bigger motor

The 350 is an older HEI system, little easier to work on, or atleast to me

 

the 350 is WAY easier to work on.
