I installed a Paxton FPR once and it didn't hold pressure. It went south because of additives I added so I replaced it with a stock FPR. It held pressure. I replaced that with a BBK adjustable and it didn't hold pressure again. I think it's just something with the adjustable FPRs.
As for your problem, what is your fuel pressure set at? What size injectors do you have. What kind of modifications have you made to the engine? Have you pulled your fault codes from the ECM? Have you done a MAF conversion?
