I switched the FPR to a Bosch 5 bar and after the install the car sputtered a little but eventually turned over and started. After sitting over night the car won't start and the dash lights up like a christmas tree and blinks as the starter cranks. Any ideas what this could possibly be? Maybe the FPR isn't working properly? I'm lost on this one, I appreciate any suggestions.

Do you have a tune that requires a 5 bar FPR? Did a tuner suggest you upgrade to the 5 Bar? I only installed mine when I upgraded software from Upsolute to UMW and the tune, along with the turbos I am running, required more fuel. Otherwise the stock FPR is fine for most who aren't boosting more power via larger turbos. If your tune isn't setup for the 5Bar FPR, you're shoving to much fuel into the combustion chambers and flooding the plugs...
