Truck Died while driving - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Was driving home today and the truck died when taking off. It turns over but doesnt start. I recently replace the ICM.
I'm leaning toward the electronic spark control module after some research.

I put some gas in the carb and still didnt start. No spark.

I think we may need a little more information about the truck and the engine to be able to help.

i would say ignition module, in the distributor

When my truck died it turned out to be a module in the distributor but I forget the acronym (87 gmc v2500 w/350).

kody · 05-01-2013, 08:37 AM

got info from 84 gm shop manual.

ramz · 05-01-2013, 08:44 PM

Changed out the Ignition Module and it started then died like it went out again....
What would cause it to go out that quick again???

meatwagon83 · 05-01-2013, 10:38 PM

look for loose or bare wires tht could be shorting it, also are the connections tight?

Doug_J · 05-01-2013, 11:02 PM

I say get rid of all that wiring and put a regular dizzy in it. Only thing that will be a pain is if you have the cali smog and a 700r4.

all hei distributors have an ignition module, do you want him to put points in it?

gchemist · 05-02-2013, 08:36 AM

He means, install an HEI without ESC connections. You can bypass the ESC if you don't want to remove wiring.

Yes sorry I was at work didn't have time to clarify what I was saying. You can bypass the ESC but why I said a regular dizzy is because the ESC dizzy does not have a vacuum advance on it. So if you're going to bypass it and to me want it to run as good and probably better then it did do it right remove that dizzy and stick one in with a vacuum advance and get rid of the wiring and the box for the ESC behind the glove box.
You can remove all that wiring without having to cut or modify your current wiring harness. The ESC crap is all stand alone wiring unless Like I said you have the Cali. smog crap and the 700r4 then its tied into that ESC box.
Forgive my spelling and probably run on sentences I'm not the best at it but I try my best to help people even if I seem to ramble on and not make a whole lot of sense at times.

This was gonna be my first guess.

ramz · 05-03-2013, 07:59 PM

I got it started... ICM
now it seems to be leaking around the carburetor linkage and also smells like something burning around carb. Like the carb is sucking for gas.. stump again
