This is driving me crazy. After I drive for 5-10 minutes, the fuel pump completely cuts off and the car dies. But then after the car is shut off for a minute or so it fires right back up.
I know it's not the pump itself since I swapped in a new one last weekend (I figure it's good to have a spare in my track box anyway). I can't find any simple wiring or fuse issues. Doesn't seem to be a general electrical issue as I still have ignition and accessory power when it happens; the Bosch CD still whines etc. It's been impossible to troubleshoot since so far I can't get it to happen idling in the garage, and it won't last long enough to probe around with a voltmeter when it does happen. This is a six with a totally redone/custom fuel system; Webers, Holley red pump regulated to 3.5psi, AN-6 lines everywhere. Anybody seen something like this before? |
