Default 02 Firebird LS1 swap - No power to Fuel Pump

We resolved the starting issue, but now Im not getting power to fuel pump. Checked the #30 connector on PCM and grounded it to try to eliminate any VATS issues but that didnt work.

The pcm pulses the ground for the fuel pump when you turn the key om,Green wire with white strip.That's what I would check out first.If not,check all the grounds on the back of the head and make sure the motor is grounded correctly to the frame.Good luck...

Incorrect. The pcm puts out 12 volts to power the fuel pump. It's the only output from the pcm that's 12v. Everything else is ground, but not the fuel pump.
