whens the last time you did a tune up?
that's something you should definately do. do a voltage drop test on that wire. you'll probably need a friend to help you crank the car. unplug a relay so that the engine doesn't start. place one lead on battery pos. and the other lead of the DVOM on the other end at the starter solenoid. crank the engine and look for any voltage drop. there shouldn't be anything at all.wire from the battery to starter solid? or has it been crimped bad connection?
