I have a 5.7 GSI PBYCCE that would act like it was starving

Customer Question

Hello - I have a 5.7 GSI PBYCCE that would act like it was starving for fuel - A mechanic replaced the High Pressure fuel Pump ( Whining ) and we did the low pressure fuel pump - the motor ran well for a minute or so then started running super rich - fouled the plugs and misses at low rpm - smooths out a little at 2000 rpm

We hooked an analyzer up to the engine and it gave error code 33 - only after installing both fuel pumps

You wrote that it was running rich. Have you checked the actual fuel pressure yet? If yes, what was it reading?
