Odd Fuel gage/pump problem
Odd Fuel gage/pump problem My 1996 z28 has a very odd fuel gage/pump problem. The car has 150k miles, and I just replaced the fuel pump 3 months ago. A week ago, it was taking a while to start, so I checked the fuel pressure. The pressure would rise to about 40psi, then drop to 0. But, once the car did start, it ran fine and held pressures at 36psi. I figured it was just a bad check valve so I ignored the problem.
A few days ago I went to start my car, and my fuel gage was all the way to the right, to the point where the needle couldnt move any further. It idled around 600rpms and then died. The engine wouldnt rev steadily, and with mid throttle it still died. I thought it was a bad fuel pump, but heres the weird part; the car ran perfect 45 minutes later. Today, a few times in the middle of driving the fuel gage needle would do the same thing, but the pump recovered fast enough to keep driving.
The last time I was driving the car tonight, the fuel gage needle fell all the way to the right, and the engine died. I pulled over, and the car started after like a minute. I was able to drive home after that, but the whole drive home the fuel gage needle would drift back and forth between the normal level and way right.
Currently, with the car idling, I can hear the pump dying and turning back on. So, is this just a pump failure? Or could there be a problem with the electricals somewhere? What can I do to find out?

I would definately say it's a wiring issue..loose connection somewhere and eventually it will burn out.
My Truck did the same thing..well except for stalling out. I have a 1999 GMC Sierra and it had the dancing gas gauge..finally the Pump died and I had to replace everything, including the Wiring cause it burned up at the Connector.
