I just brought a 1993 4x4 pickup with a 22re and a five speed. The person that owned it before me took it as trade for a deck job along with a 1995 2wd auto parts truck. The '93 motor was locked up so we swapped the 95 into it. Now it doesn't start. The circuit opening relay clicks and the fuel pump works when bench tested, the blc terminals are too nasty to get a jumper wire into. Someone said if the 2wd had a dummy light for the oil pressure the sending unit may be different. Any ideas? Or am i even going in the right direction?
