2024年12月8日 · My truck is running at max rail pressure (around 26,000psi +/-) at idle. Commanded fuel pressure is somewhere around 6600 psi. I have tried two different Fuel Control Actuators with no change. Truck is stock other than a Fass Fuel system. The only code showing is P088 for fuel rail pressure too high.

2013年1月1日 · Here recently my truck has been throwing P0088 Rail pressure too high codes at random. I have been trying to figure out a pattern for when it happens, and it seems like it only happens when I am slowing down and almost at idle. Truck runs great and I just can't figure out what the deal is. If...

2010年2月3日 · I've been getting a "Fuel Rail Pressure Too High" fault code every once and a while. Has happened about 4 times now over 3 months. Usually happens during very light acceleration, or while at idle. Has only happened when running the factory calibration, but then I only use the race box tunes...

Check the code and it shows P0088, high fuel rail pressure. Took out the Tech 2 and have a Commanded Pressure of 5838 and an actual of...

2021年6月19日 · Ok guys I came out to my truck not turning over one day, checked fuses and found the ECM 1 fuse had popped. Replaced the fuse and now I have been dealing with P0088 (high fuel rail pressure). At idle the truck stays around 13500. I've changed the fuel pressure sensor 3 times and I've also...

2017年5月20日 · Ok I drove the truck today. I pulled connectors on cp3 and fprv and Ice picked them to make sure they were connecting the truck was still having high rail pressure but I reset codes with the engine running and started driving it before code set again and as long as I was applying throttle the truck drove wonderfully very quiet and smooth but if I tried to get on it it fell on it's face and if ...
