SOURCE: I HAVE 1988 FUEL INJECTED 5.7 BLAZER
Chk. the egr valve for vacume and if it is functioning, might be pluged up with carbon deposits.
SOURCE: 1995 chevy 1500 4.3. motor turns over but no start?
It could, if the fuel pressure is less then 60psi. Check the fuel pressure at te shredder valve, there should be 60 to 65psi to have the fuel injectors to work. If there is less then that, then it's a good chance that the fuel pump is going to have to be replaced and the fuel filter. To keep it simple, replace the fuel filter first and see if that get's the engine running. The other thing to that would cause this is a bad ignition control module (ICM) and that is located at the distributor. Good luck and keep me posted, be glad to help you get your jimmy running 100% again.

You could possibly have to replace the spider injection assembly. Or the regulator unit to the spider injection rail.
SOURCE: 1988 chevy will not run,fuel injecter will not
turn the ignition to the on position without starting the engine. you should hear the fuel pump running for 5 seconds inside the fuel tank. if not heard replace the engines oil switch. that starts the pumps circuit when the key is turned on. after the engine builds up its normal oil pressure the computer shuts that oil switches circuit off and turns on the fuel pump relay

Change MAF. Mass air flow sensor. Best place for something that old is probably an auto wrecker.
The computer controls the injection of the fuel. If you look at the wiring diagram you will note the bottom 4 pins that are the negative and positive to the left and right injection. Atleast on my 1991 it is .Could be the ecm or computer is sending a false signal or not sending one at all. A sign of this is the fuel pump in the gas tank can be heard and will continue to run as if pressure in the fuel system is not building. Tthe truck want crank as if no fuel. When starter fluid is injected into the Throttle body the egine will start and run untill fluid is used up. It will keep running as long as fluid is added.
