Been there before!!!! usually it turns out to be something really dumb that makes you say "Why didn't I look at that first???" (either while you are smacking yourself in the head , or, just after!!!!)
Good luck again!!!

check the valve timing after replacing the chain. check that you connected the ignition module to the coil. Check ignition timing as you may be out 180 degrees on the timing.

I had the exact problem with my 1993 chevy c1500. I found that the IAC was sticking so the engine would die at idle after warming up and the ignition module was pulsing the ECM intermittently after the engine warmed up so the fuel pump wasn't being turned on after the engine died....I replaced the ignition module and the IAC valve and all is good. I don't know if testing the ignition module reveals that it isn't sending pulses to the ECM.

The first thing is to make sure you are getting fuel to throttlebody see if it sprays,this year is fuel injected not carburated, if so good. next is to test for spark. remove a plugwire and stick a screwdriver into the boot and place screwdriver near metal ground have someone crank motor and see if theres spark, it sounds like you check everything except spark the most common problem with these would be the ignition contorl module,this is located under the dist cap, remove two connector and two screws and it removes have it tested at parts store, this when bad may also stop the injector from spraying fuel, this sounds like its your problem, they are easy to replace. hope the helps and also herea picture of the control module.86262cc.jpg

92 chevy 1500 5.7 tbi starts and dies. replaced fuel pump and filter, tbi,iac, and tps, still has same problem. fuel spray seems weak at injectors. could it be the module in distrbutor?


Try using a good fuel line/injector cleaner Seafoam is a good one. If this does not help you may have tone or more clogged injectors. Clean these out and you should be good to go. tTo see Seafoam in action goto you tube type Seafoam into the search box.
