Hello, my name is***** check engine light come on for bulb check when first turning key on?
You say the fuel pump fuse does not have power, that would point toward fuse box failing. Take a wire and jump directly from battery power to fuse box fuse. If that allows it to start, replace fuse box. Here is a wire diagram to help with testing, let me know if you have more questions. Thanks.
Main power wire that feeds fuse box, feeds the fuel pump fuse. So if fuel pump fuse doesn't have power but other fuses have power that would mean the fuse box has failed. Let me know how it goes or if you run into more questions, thanks.
Ok, 86 gets power from PCM pin 14 of connector 1 via dark green/white wire. Check to see if wire at PCM has voltage while trying to start. If wire has voltage at PCM check to see if dark green/white wire going into fuse box has voltage, if not run new wire. If wire has voltage at fuse box but relay doesnt have voltage that means fuse box has failed. I think you may be looking at diagram wrong if your looking at same one I am which I included in link above. Let me know if you have more questions, thanks.
