Neither will mine. I've tried my tech 2 and efi live no luck. So I can't get and don't have any codes, no fuel pump, or odometer. I've got nothing. It just cranks.

Hmm ok, As long as you are sure that the ignition is getting ignition to the ecm. when key turned on, all pink wires on the harness and going to the computer should be getting 12V, and the orange wire should be getting 12v. If thats the case, then a replacement might then be needed. Pretty rare..

I've been trying to follow wires to check that. That's why I replaces the key switch also because it had the wire casing cracked and had exposed the wire.

New fuses and relays did not work on mine. That's what I checked and replaced first.
