Major Problem Need Help

[silver_pilate]

Here's what happened with my fuel pump. It would run great, for a while. After a good drive (usually with lots of highway cruising), the pump would overheat, crap out, and then leave me stranded. Ran fine on the highway, but at the first traffic light or the first time I slowed down, the pump would start to drop pressure. I verified this with a fuel pressure gage. When it died, it wouldn't build or hold any fuel pressure until it cooled down. I would have to let it sit for 20-30 minutes before it would run for any amount of time. Starting it up when the pump was hot resulted in it not starting at all or running for a few seconds (or a few minutes, depending on how much it cooled down) before the car stumbled, stalled, and died again.

And that was with an aftermarket pump.

So I put a new Holly in and all is well. Put a fuel pressure guage on it and see what's happening.
