The problem began when car suddenly died, replaced fuel pump, further inspection showed efi fuse blown, replaced fuse still no power to fuel pump, checked efi, main, and cor relays. All are working show no resistance with a meter, still no power to fuel pump, fuse blew due to o2 sensor wires touching manifold, repaired wires, efi fuse does not blow when vehicle is cranked but car still will not start.

Just so you know, I went with "except California" (49 states) and I used "XL"

I found the fuel pump.

It is hooked to a relay called "circuit opening relay". Prodemand says it is located in the right kick panel.

There is a wire from that relay that winds up in the "instrument panel junction block". This wire connects with "Ignition Fuse" and it is a 5A (5amp)

Another wire goes to the ECM from that relay.

If I were grasping for straws, I would pull that fuse and inspect it, heck, it may have lost contact with corrosion on its legs.

As far as the relay, I would look for its "twin" (like for windows, etc.) And just swap 'em out to see if things change (before you spend money for a test)

Hopefully what I found is something you may have overlooked.

Good Luck!

Give us an update.
