Im sure I posted this before about the sons 97 GTP.
It would stall out and wouldnt restart.
He replaced the pump and it seemed OK for a while then did the same thing again.
We finally pulled the passenger seat and rear seat and traced the wiring back from pump.
under load I found the pump had 7-8volts and wanted to find where the voltage drop was.
I ran all the way back to the resistor for fuel pump,shunted it with battery voltage and car fired right up.
I then found out that the ignition switch is split into two circuits and the half that has fuel pump was flaking out. $45 wholesale for a Delco and we were in business. I still have that old switch,dont know why but keep it has a reminder to never use a test probe(light) when looking for a voltage drop problem.
