Fuel pump going out or something else???
At strip today, following happened; 1st 2 runs car ran fine down 1/8. 3rd time, just as I caught 3rd gear car bogged down then shut off. Looked at fuel pressure, it was showing 30 psi. Let it coast a bit and it started right and showed 60 psi. 4th time, doing burn out, car stumped, pressure went to 30psi and stayed until about 3/4 down track and then shut off. Let it coast and started right up and showed 60psi.
Pulled back to garage area, turned off and it sit. Pressure showed solid 60psi steady even when I got on it.
Details on car- blower, 60lb injectors, stock fuel system and BAP
Pump going bad, needed upgraded or both?
Thanks

Stock fp and bap should be good to at least 600rwhp.
It's likely you have an issue in the wiring (intermitten short) somewhere. It's way more common vs bad pump. First thing I'd check is the connection at the fuse block. Then start tracing wiring between the harness to the bap, pump module connector etc.
If you haven't already, you may want to consider the Racetronix harness (bap set-up) that eliminates most of the oem fp wiring issues.
Which bap are you running? I've run several and all have failed except for Kenny Bell.
Also, I'd stay out of boost until you have this sorted out.

Have the Kenne Belle unit. Funny you mention the fuse area, I had an issue there a few weeks ago. I read another member's post and used his repair where he added solder to the relay legs to make the socket fit the legs better.
Thanks for reply
