Welcome to the TDR. Can you fill out your signature or tell us more about your truck, like what kind of aftermarket parts you have, if any. Do you have gauges for fuel pressure, Boost, EGT??? Whats your milage at, have you had any previous troubles with the Lift pump??? Ever been replaced???



P_PCU is not a code, the codes would follow this prompt, like P-0XXX then you should see P_ECU followed by more P-0XXX if you have codes.
