I put a FASS system on my truck a week ago and has ran fine. I just purchased and installed a full egr delete with y-bridge, fuel filter delete kit, and new deleted exhaust. After installing everything including the tuner it started then quit. We had removed a couple fuel lines to remove y-bridge so i assumes there was air in the line. We then got it started after priming it. I went for a drive and it ran like a dog. If you barely pushed the gas it ran normal. If you got in it at all it would fall on its face. After a few times the fuel rail pressure code kicked in. I figured once again air may have been in line. I then reset the code and it started right up and ran fine. Drove 45 mins home and ran fine until right at the house i tried getting in it again and same thing happened. I then left the house for a long drive and for the first hour or so it did fine. Then the code just kept happening and limo mode until now it won’t start period. Had to call a wrecker for it. With the fass system don’t see why this would be an issue unless it was the filter delete. Any help at all would be appreciated.
