The 1990's chevy trucks(all of them) had fuel pump and grounding problems:
1. Check the fuel pump ground strap next to the gas tank as it could be broken from the connector or just loose.
2. Have a fuel pressure test done on the fuel lines at the engine top. (Note: if there isn't enough fuel pressure, replace the fuel pump.)

Disconnect the + wire Coils Take #1 Spark Plug Out Get a helper Use Compression Guage if not Available, Just put your finger over the Spark Plug Hole, have help BUMP the Starter over till You can Feel The Compression at your finger you need #1 at TOP DEAD CENTER on its Compression STROKE Fine tune it by using a STRAW in the Plug Hole to feel the PISTON Move UP To VERY TOP Dead center----------------------------------This is Tricky but don't Loose these Instructions------- If you have the OPTI_SPARK Ignition System My Books show all about it but Nothing on the Timing "MARK" as this is the step I Stoped at Above.. Coil Pack Ignition Will Have a Timing MARK On the Lower Harmonic Balancer. Point Being if Mark is NOT on the Degree Indicator It has JUMPED TIMING<< Surly on a Coil Pack Ignition System BUT
-------- The Opti Spark system if there is NO Timing Mark to Go by I Would Suggest Breaking Down and Letting A DEALER Handle it Unless You Can RULE that it HAS JUMPED TIME------------------------------------------------------------------------I Truly Hope I've shed some Light on Your Delima and this Leads you to a Smooth running Chevy. PLEASE don't forget to Rate Me ------------------------------------P.S. The Opti - Spark System Has A BAD REPUTATION Just FYI

could be a vacuum leak, also get rid of the quadrajunk carb it will prolly help
SOURCE: Engine starts then dies, replaced filter,pump,and
check fuel pressure to the fuel rail to see if you are recieving fuel to the fuel rail if so the injectors are suspect
SOURCE: 1996 Impala SS car hesitates upon acceleration
if after setting for a while will it re-start if so look at fuel pressure regulator chevrolet does not recomend but these are adjustable and will fix problem find good drivability person with gm background can fix you make some calls

Crank sensor has to be bad,or the ignition module.Remove the ignition module and have it checked at the parts store.If it checks bad,replace it,if it checks good replace the cranksensor.The cam sensor,cranksesor,and the control module control injector pulse,and coil spark.I would point more to the ignition module.But I have known the crankshaft sensor to do this also.I hope this was helpful,if so,let us know,thanks,and good luck.
