Im testing my fuel pump ( bridging the 2 pins) and we'll I'm getting nothing coming out not a hum nothing.
Before I remove it and exchange for a new one is there any further tests I can do ?
It's the original pump and a 91 car

Take the plug of the pump and bridge the pins again then check with a multimeter that your getting 12v at the plug. At least that will confirm the wiring is good. I am assuming you have checked the fuse
