Thread: 99 gtp starts then dies..

The outgoing power from fuel pump relay doesn't go straight to the fuel pump. It goes out through a fuel pump resistor and then back up to the f/pmp spd cont relay. I think its right beside the f/p relay. So the f/p relay would be hot at the #30 terminal goin out and the f/p spd cont relay would be hot at #87A goin in. Could be the resistor.

You'd want to test power going to the pump before changing a pump. Nacho his it on the head when he asks about the fuel pump speed resistor. When the key is turned the car primes. Then that pressure in the line will bleed off like you mention unless the pump kicks back on. This is very common.
