I know you said you replaced the connector on the fuel pump, but are you positive that's not the problem again?

I had these same issues that presented themselves as alternator/battery problems and after a search through the archives came up with the fuel pump connector have issues. My boyfriend (RobG) talked to Jerry Lemond about it for hours and Jerry said he's seen the problem alot, even with replaced connectors. We ended up just sodering them together permanently and I haven't had a problem since. <img src="/forums/images/graemlins/confused.gif" alt="" />

Rob and Jerry also did some other troubleshooting to narrow it down to this. Maybe Rob will chime in if he remembers what he did - I know it involved jumping lots of wires around the fuse box.

Good luck.. stupid electrical gremlins are so annoying! <img src="/forums/images/graemlins/cheers.gif" alt="" />
