Question about 1995-1997 Chevy 1500 Truck Ignition Starter Alarm Switch
The truck drove fine then I stopped to visit friends then it would not start. It turns over but won't start. I changed the rotor button, distributor cap, ignition coil, crank sensor, still no fire. Sounds like it wants to fire but won't start.
You need to check if it is a spark problem or a fuel problem. Check to see if you have spark to the plugs by removing a plug wire from the dist cap, hold it 1/2 inch from the tower in which you pulled it from and have someone crank the engine over. If you have a strong spark, then it is a fuel problem. Take off the air cleaner and squirt some starter fluid into the throttle body. If it starts you have a fuel problem. Check the fuel pressure with a pressure gauge. Should have 45-50 psi depending on engine. If you have no pressure check the fuel pump fuse in fuse box. You may have a bad pump. You might try tapping the lowers part of the fuel tank with a hammer while someone else is cranking the engine over. Sometimes that will jolt the pump into pumping.

It's clear that you have a fuel system problem, if the engine will ignite only with starter fluid. Injectors do not spray when engine cranking, even the fuel pressure is good enough = 60 psi. Then remove the fuel rail assembly with injectors and see if they spraying fuel when another person cranking the engine. If not, check the electrical power supply of injectors & repair wires, connections, ... Also verify the Engine Control Module (ECM) output power towards injectors.
