maybe u have a fault in your fuel system instead, do you smell gas when ur cranking; if not then ur are not sending fuel to the engine. sometimes faulty wiring could be to blame. as it turned out to be in my 85. and as funny as it seems when i rocked the truck i got it to work, so my problem was probably a loose wire rather then a short. i know how much this sux, i used to leave work after a crappy day and couldn't even drive off at times so hope this helps

I have heard that it was a control module problem so i went to the junk yard and picked up a gm one and had it tested thought it was alright but today i had the problem again, I dont think its a fuel problem

It sounds like your ignition module in the distributor. I had an 88 S-10 Blazer that had the same sporatic problem. A stranger walking by one time when it was acting up told me what it was and it would start for me in about 15 minutes after it cooled down. It did, I went to Auto Zone and bought the module, changed it and it never happened again. Funny but I've never considered buying electronic parts used from a junk yard. Seems like they are always too exposed to the elements to be any good.

Does it only do this when the engine is warmed up?
Meaning, it starts up only when cold?

I'm gonna go with Blasir on the Ignition module.
I bet if you let the truck cool down, it will start up.

the one i got from the junkyard i took to autozone and had it tested before i put it in yesterday. The truck starts fine while cold now it used to overheat, but thats why i had new heads put on so now it don't overheat but still having this problem. Yesterday after puting the module warmed up the truck drove it around my and my freind where doing the timing had it running for a while starting it and stop overand over, took my truck home and let it sit. Today ran around a little bit at 8:00 let it sit then was going to go back around 10:00 the truck would not start then at 11:00 it started, So I don't know whats going on with it.

And it is actually pretty easy to change, but I had to do it outside in 20 degree New England weather at the time. I had to stop every 15 minutes to thaw out my finger tips. In better conditions it looks to be about a half hour job. You should see it under the distributor rotor. It's a black flat module with 2 connectors, one has about 5 fingers on it. Been a while, but I think that describes it closely.
