fuel pump not running

[dusterbd13]

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.

It should run for so many seconds when you turn ignition on to bring pressure up,then stop.Turn key to start engine starts then pump runs.

[dusterbd13]

youre corect. so far, i cant even get it to prime.

[dusterbd13]

got it figured out. didnt have proper switched power into the ECM. the fuel pump was wired right, just missed the obvious.

thanks for all the help
