im working on the 3.4 swap in my s10.
particulars:
1987 s10. 2.8 TBI truck.
1994 3.4 firebird motor. MPFI and DIS retained. all f-body sensors.
1993 lumina 3.1 engine harness and PCM:7727
i heard it fire on the ether tinight. near as i can tell, everything is hooked up properly, as well. if i jump my tan/white wire from my furl pump relay to power, my fuel pump runs. if not, it doesnt. have constant power in, wired into the fuel pump relay pin on the ECM and the fuel pump pin. i think its all right, but it doesnt run the pump.
so, anyway, can somebody look at some diagrams and tell me what goes where? my head is stuck in the ay i hav it done, and i cant seem to figure out where i went wrong.
