Code 54 Help needed
Im gettin a code 54 which according to our faq means
Low voltage at fuel pump OR
Low voltage at Fuel pump relay OR
Output failure at quad driver module
im guessin im gonna have to break out the multimeter... but where exactly should i look?... the plug goin into gas tank ? any others?
never had this problem b4 .. jus wanna kno wat i might be lookin at parts wise and $$ wise
thanks guys

Go to the TPI board and do a search, I know the diagrams been posted many times before.
IIRC, the 12 v is fed back through the relay to the ECM, if the voltage is too low or too high, then the appropriate code is set.
Once you find the pinouts for the FP relay circuit, it's much easier to troubleshoot.
Good luck
