Buick Regal GS: I have a 1998 Buick Regal GS supercharged.

Customer Question

I have a 1998 Buick Regal GS supercharged. When I turn on the key, I have no noise for the Fuel pump. I have two Fpump relays and have swapped them. I can hear and feel them actuate when key is turned on. I have 12v for 2 seconds at the Fpump connector on the grey wire. I have 5v on the purple wire at the Fpump. So I swapped the Fpump. Still no fuel pump noise or pressure. I jumped the grey and green wires on the Fuel Pump resistor and still no Fpump noise.
Out of ideas.

good afternoon my name is ***** ***** I will assist.
you have all the proper signals back to the fuel pump connector.
1. swapped fuel pumps??? new pump???
2. did you replace the connector or did it not come with the module???
3. most common issue is the ground. the heavy black wire is the ground for the pump. check the voltage on that line. if you have any voltage, the ground is bad. you should read 0 volts.
lets start there
