Code 538 - Brief wide open throttle not sensed during self-test or operator error
Code 542 - Fuel pump secondary circut failure
The first one is probably from not hitting WOT at just the right time.
Code 542 could be a short in the secondary circut, or the fuel pump relay contacts are always closed. It could also be a bad ground for the fuel pump.
Hope this helps.
