Message: [QUOTE="DcMoore, post: 1549151, member: 382"] Last week I was pulling my camper and I get a P228F(Regulator Exceed Control Limits) and P0088(Fuel Rail Pressure Above Max Limit). I cleared the codes and all was well. Got to the destination, shut the truck off, restart, and code P0088 comes back. Once the truck was running I was able to clear the code and it got us home. No change in difference between actual and desired fuel pressures. The next day driving to work I tried to clear the code but it kept coming back. Fast forward, new regulator installed and it is still throwing the P0088 code. See the photos below. Regulator that I pulled out - no rust but destroyed. [ATTACH=full]179490[/ATTACH] New Regulator - for comparison [ATTACH=full]179491[/ATTACH] Pulled the metering valve (Exergy MPROP) and it is fairly clean. The other side of the valve is super clean. [ATTACH=full]179492[/ATTACH] Does anybody know what is going on here? Should I replace the fuel rail sensor or the metering valve? I don't want to run it long and destroy another regulator. Thanks!
