Has ne1 ever encountered this code, and if so, what did you do to fix? Could be any one of 3 areas. 2 have been eliminated- PCM is technically working, as the pump turns on during run for 2-3 seconds (engine off), and notices the engine is off, cuts off. Car does run fine (just loss of power). Pump is good (?), just on and off, right? Leaves Constant Control Relay Module, right? Please help, I'm getting my butt whooped by my friends Yugo!?!?!?!?\\

BTW, I have a 95 5.0

Thanks in advance.

Code 542 is Fuel Pump secondary ciruit failure

Sounds like weak pump / high resistance in pump [eletric circiut]

No I don't think it is your Constant Relay Module. If you are not sure, take the module to your nearest Ford Dealer and have one of Tech to check it out. Ford Dealer has the tester to check the relay module.

Thanks, just trying to go with the cheapest, easiest fix possible. And it's beginning to cloud our judgement. We knew it had something to do with fuel, just not sure when we pulled the code, and looked through the schematic. We'll try to check the module.. Should be free to check, right? If that's good---- Fuel pump?!?:eek: :eek:
