IS THERE A SECOND INLINE FUSE FOR THE PRIMARY ELECTRIC TO THE FUEL PUMP?

1998 Plymouth Breeze • 165,000 miles

I can start my car by pumping the gas and then keeping the rpm above 2000 it runs without pumping. When I go below 2000 rpm, it stalls out and won't idle. Acts like it's starving for gas. I don't have a pressure Gage, but at the test valve only a trickle of gas comes out. It's a brand new pump.

I have it in a test mode. I took the gas tank and the fuel pump out. I have a three gallon open top tub of gas in the trunk with the fuel pump plugged in with the bottom 2/3 submerged in gas. I have a short hose on the fuel filter connection running back into the tub.

The car is a standard and requires having the clutch engaged to start the fuel pump and the starter. The starter works but the pump doesn't come on when you turn on the key and engage the clutch. When you use the starter, the fuel pump squirts gas in rhythm with the firing.

The only fuse box I can find is under the hood and all fuses look find.

Is there a second inline fuse for the fuel pump? If yes, where do I look for it? If no, where do I start looking for the problem?

Thank You.

You're describing how a MAP sensor can fail. The engine will run as long as the gas pedal is moving.

The fuel pump should run for one second after turning on the ignition switch, then again during engine rotation, (cranking or running).
