We are having a FP problem...as in the pump isn't making enough ! Was racing at Mid-Ohio and the car literally shut down. We have ignition and injectors are working. Pump, fuel filters, and pressure regulator all all brand new. We have tested it at the rail and at the top of the tank...All lines are clear. We bypassed the wiring harness and wired up the pump direct to a 12V source as well...Totally stumped...Any ideas or suggestions out there ? Thanks !

I had the updated pump previously however i replaced it with a brand new pump on Wednesday.

Either the new pump was installed improperly or it is defective.

Have put in two separate pumps just to make sure. same results.

Partially crushed fuel line? When you say "shut down" as in goes into limp mode or just reduced power?

Got it running...one of the ends on the "outrigger" suction tubes had popped off way down inside the tank...very tiny little clip wasn't snapped in all the way....
