Last week the car would randomly loose fuel psi for a split second stumble and regain its composure. It would do this on and off. I thought the BAP was bad so I bypassed it to the stock fuel system configuration. This worked for a day. Now its doing it again but with a twist. The instrument panel blinks off then on and lights up like an Xmas tree then normal. did that a few times on the way home today. car never shut off but all gauges and radio and such would.
Ive searched for any loose grounds or power wires and can find none. NO CODES either.
Thanks. I did find a loose battery wire at the main fuse box. Had to crimp the end back. That fixed the problem of the car shutting off at random however, I am still having a fuel pump stall. As previously stated it is only for an instant like a stumble, but it is getting more frequent. There is no certain speed or rpm range this happens at.
Bill, got the PM sorry I could not call you. Been tied up with a death and long distance move and nursing the car at the same time.

Not sure what the history of work done/mods on your car is. The fuel pump relay is grounded at SP122(splice pack under the battery tray), and that splice pack receives it's ground from G105....lower left side of the engine block. The fuel pump is grounded on the left rear frame rail, behind the wheel well.
