Chevy 3500 Express truck. fuel problem?
I have a Chevy 3500 Express truck. I am getting 3 codes. 1:P0200 Injector circuit open 2:P0200 Injector circuit open (pending) 3: cylinder 5 misfire (pending) Key on fuel pressure is 50psi and running is 52psi. The fuel filter has been changed. Cap, rotor, wires, and pvc also changed. The engine idles good but under a load it runs rough and has a strong odor of raw fuel and smoke from exhaust. Any ideas? Thanks Joe

Hey Joe. What year is the van and what engine do you have? Also, you mentioned 3 codes but you've only listed one (P0200)

IF YOU GOT CYLINDER MISFIRE.OR OPEN FUEL INJECTOR.THAT WILL CAUSE THE PCM TO ENRICHEN FUEL MIXTURE.TO ADJUST TO DEAD CYLINDER.WHICH ACT AS A LARGE VACUUM LEAK.THATS WHY YOUR EXHAUST TAIL PIPES HAS A RAW FUEL SMELL AND WHITE SMOKES.
