Just an update - I installed a new HPFP over the weekend, but I'm still getting some of the same codes:
2BEE - High fuel pressure, plausibility, cold start: Pressure too low.
2EE0 - Combustion misfiring, several cylinders: Fuel injection deactivation.
2EE2 - Combustion misfiring, cylinder 5: Fuel injection deactivation.
2EF1 - Combusion misfiring, cylinder 5: damaging exhaust gas after start sequence.
2EFE - Misfire, several cylinders: Damaging to catalytic converter or damaging exhaust gas.
2F03 - Misfire, cylinder 5: Damaging to catalytic converter or damaging exhaust gas.
So I pulled the coil packs and plugs, which are about 4 months old. The plug in cylinder 5 had a lot of fuel on it and maybe that's why there's no combustion in that cylinder.
I ordered a new plug to replace that one and will validate all plug gaps before installing again. I'm also going to swap the coil packs from cylinder 1 to 5 to rule that out...
Any other suggestions for what I should try?
