Default 1994 dodge ram no spark no fuel pump.

Okay so i have a 1994 dodge ram 318 5 speed. Starter went out. Replaced it. Ran for a day. Then quit. I knew it needed a tune up so i put a new cap rotor plugs and wires in it. Wouldnt start. Put new cam sensor and crank sensor in. Still has no spark. Inhooked the battery last night. Called it a night. Went out this morning hooked the battery back up. Positve cable arked and lost fuel pump. I tried a a pcm off a 95 360. Still nothing. Not getting power to coil. Any ideas?

I swapped the fuel pump and asd relay. No change. I replaced both relays. No change.

Jump the ASD relay, see if it starts.

If you don't already have one, grab a service manual from here. Wiring diagrams are in section 8W. ASD relay should be in Fuel something or other..... Check and see which pins you need to jumper with a wire, to give power to the coil, and injectors. See if you at least get spark.

In the ASD Relay socket, jump pin 30, to pin 87. They should be labeled.

Now that is definitely different. Can you plug a scanner into your truck, and actually communicate with the PCM?
