Bad ground affecting ignition?

A few months ago my 90’ Teg started having trouble starting. I figured out that the ground strap that connected the starter to ground was not well connected (high resistance) to the ground at the battery or other ground points in the engine. So I ran a heavy gauge wire directly from the battery to the starter and it fixed to problem.

Recently my car started running bad. It seems sounded like a ignition problem the way it was running. For a while it would start but then cut out when I went over a bump or semi-randomly. Now it will turn over but not start. I should add the all the electrical systems in the car seem to work fine. I think the broken ground wire that I never fixed in the first place is effecting my fire. Has anyone else ever had that engine ground wire that ends at the starter and drops off at other places along the engine go bad? Where is the ground connection for the coil/ignition, so that I can test for electrical continuity?

After I managed to get the rusted bolts out from under the battery. I managed replace the ground wire that runs between the engine and chassis. I also cleaned the under the ground mount to the engine with a wire brush and used some OX-GARD to prevent future oxidation on all three ends of the ground cable. Now everything is working fine. Bottom line … a bad grounds causes all kinds of weird problems and even if measures reasonably low resistance it still be a weak connection.

I wish more people posted when they find the sollution to there problem :up:
