I am working on my neighbors truck for starters. Came home parked truck and wouldnt start again. Started out with no spark so we replaced distributor, dis cap and rotor, plug wires and even put in a used but working PCM. Spark returned but injectors wouldnt pulse. Now it seems injectors dont pulse all the time when key is cycled on So it throws code 27 intermittently. Also when injectors don't pulse fuel relay doesnt kick on either. When I put a noid light into cylinder 1 injector the truck tries to start but stumbles and dies. After got injectors kinda working lost spark on cylinders 1&5. Ignition relay under dash gets very hot to the touch after trying to crank.

Forgot to mention also changed coil. The spark loss is also coming from coil. I can connect my timing light to it and it has a clear gap in spark. It'll flash a few times then delay then flash a few times. It does this when trying to start it. Also when injectors stop working so does fuel pump. When injectors work fuel pump comes on.
