My 97 4.0 cranks but does not fire. There is no power getting to the coil and none at the fuse. also the fuel pump is not kicking on. I have changed the relays, cps, checked the fuel pump and now I am stuck and on the verge of replacing the ecm. What am I missing? What else can I check to help narrow it down to the computer? Is the computer directly responsible for activating the relays and is there something else that will prevent them from switching on. I bridged the auto shutdown relay which is responsible for sending power to the coil and still no fire to the distributor. I understand that the computer is responsible for sending intermitant ground to activate the coil. How can I test my computer?
