542
542 = Fuel pump circuit failure.
The question is what is causing the failure.
You should hear the pumps run for a second when you first turn the key to the on position.
I am guessing that you will not. I am not sure what would cause that code off hand, but I would start with testing for power at the pump and see if it is not just the pump that is the problem.
Again, I am not familiar with that code, but if you do a search, I'm sure you will find info on the issue
You can also check the inertia switch, fuel pump relay, wiring....
