What are symptoms of no start and no fuel pressure?
It may also effect 4.6 and 5.4 vehicles but I kinda doubt it. Symptoms are a no start and no fuel pressure at the fuel rail. Fuel relay tests good but not receiving switched input signal from PCM. Fuse 24 (30amp MAXI fuse) is blown for PCM. Loading…
What causes the fuel pump to not start?
The fuel pump is running and delivering normal pressure to the engine But, with all that working your engine still will not start. So, the most likely cause, is that the fuel injectors are probably not opening. The (PCM) uses the trigger signal from the crankshaft position sensor; and/or camshaft position sensor to pulse the injectors.
Is there no fuel from injectors to start truck?
No fuel from injectors to start truck. When I try and start my 93 Chevy Cheyenne k3500 no fuel come out of the injectors. If I use starting fluid the truck starts and the injectors work great. Has died a couple times while driving, but mostly runs fine and then won’t start one turned off.

What to do if your truck won’t start?
Check the injectors harness with the key on and the engine off without trying to crank. There should be a voltage on one side of the harness supplying fuel to the injectors. Then crank the engine and back probe the wires to see if there is power on the other terminal on the harness.
