newbie questions

[bill302]

ok, im a newbie here and i got a problem.
my check engine light is on, it is throwing a 543 code (fuel pump secondary circuit failure, battery to pcm).
what the mess is that?
light is only on every once in a while, more off than on, but is still enough to pose a possible problem.

Is the car running bad in any way? Or are you just getting the code?

My guess is there is a loose wire connection for the main fuel pump wiring. Time to trace the wiring and inspect/clean all of the connectors.

I had a CE light awhile back for something (cant recall what) but it would go on and off too, and it WAS a loose wire.

My friend's 95 GT throws that code from time to time. IIRC, it's just an intermittent power failure (probably wrong) but it doesn't effect his car anyway. He's not worried about it and I'm not either.
