Without rpm signal, there will be no injector pulse. Any applicable mil codes? You can check voltage and ground for the injector/s. Use a gage and check fuel pressure.

i don't have a gauge but disconecting the fuel lines and jumping the relay gets me a good stream of furl to the throttle body. i put a test light in the injectors and one side of each of them has power. I think the white wire on one and the red on the other not sure but one each. is this right?


how do i test the ignition module in the distributor?
