No! I don't know off hand what a code 542 is, but , can you hear your fuel pump running when you turn the key on?
 
if you cant hear the fuel pump for 2 seconds when you turn the key on im thinking fuel pump i never had trouble with anything else if you hear the pump i would be looking at the fuel pressure regulator
 
Code 542 means there is somthing wrong with the secondary circuit in the fuel pump. So try swapping another in there and see i it fixes it.
 
I can't help but wonder if it's that 18 inch connector harness that plugs into the fuel pump on top of the tank. Maybe disintegrated. 542 cause?
 
Yes ......

A GROUND WIRE UNDER DASH WAS DISCONNECTED......:rolleyes:

GOOD THING I DIDN'T DROP THE GAS TANK ....:eek: OH WELL

THANKS GUYS FOR YOU HELP
