I replaced the eng and tranny in my full size 90 Blazer with a crate 350 and rebuilt 700r4,both from dealer.the old engine was running,but had a bad knock..OK... I installed a new fuel pump,filter..But the problem is I'm not getting fuel to the TBI now..I don't get it,it worked before!!
there isn't any power getting to the fuel pump,the fuses are good,everything is pluged in,fusable links are good,relay is good.
I ran a wire from the positive side battery term to the fuel pump,and the pump pumped,but still nothing at the TBI.
But when I try to get a code from the ECM,the check engine light is not on,the bulb is good. CAN SOMEONE PLEEEEEEEEEEEEEEEEZE HELP!!!


Thank you for your support!!!!

The SES light should come one with the key turned to the run position...does it?
You may have left a wire loose during the engine swap...happens....check the grounds!
Remove the injector connector and install a test light..spin the engine over..does the light blink?
