Thread: 99 Regal GS fuel pump issue

My girlfriend is having a problem with her 99 GS. Car shut off and acted like it wasn't getting fuel. Fuel pump relay was replaced and no go. A wire was ran directly to the fuel pump and the fuel pump runs.

Now the car is 300 miles from me so I am going off description alone, but I am told there is a click being heard back by the fuel pump when trying to cycle it/prime it.

Any advice?

Okay, I was typing that while holding the phone.

Here is everything I know.

Car stalled out the other day. About 10 minutes later it restarted and go to the destination only to not restart when trying to leave.

Fuel pump relay was first thing changed and that did nothing.

Fuel pump was just replaced last year. Fuel pump resistor is already bypassed.

A hot wire was run directly to the fuel pump and it runs with that, but does not run when the key is cycled on, however they are hearing a "click" back in the fuel pump area.

If I was physically there I could probably already have it running. Even if I didn't have it running I could have done more diganostics and given a better description. Any advice at all is greatly appreciated.

I believe there is a fuse aswell with the relay, also maybe check the IGN fuses.

The hotwire..run straight off the battery?

If they are putting power directly to it and it doesn't run, then ground is missing or the pump is bad. On the fuel pump, the pcm controls the power, not the ground.

Bill, from what I understand they ran a hotwire off the battery and the pump ran but it wont run with the key so there is no power at the pump.

Hmmm

If security was an issue it would run the pump in high speed for a second to prime the cylinders. Then it would start and stall. Very much like a bad resistor. Getting nothing, I'd check the relay and fuse. Keep in mind, you'll only have power for a second when the ignition is first turned from off to on for that prime. After that..there won't be power again until the engine starts.

I really wish I was actually there to mess with it. I would test for power to the relay, power leaving the relay, I'd hotwire the pump and try to start the car, etc, etc, etc.

The guy working on her car is mainly an internet mechanic from what I understand. He really doesn't know anything without looking it up.

As I was typing this I was talking to my gf, so I told her everything I had gathered here, which is basically what I told her to tell him to do already. We'll see.

Thanks for the help guys.

Try talking to him directly. If you'd like the schematics..I have them for the regal.
