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.
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.
