bad ground? sometimes cranks, sometimes dont.

can someone help me narrow down the issue i'm having. i'm kind of at a loss. i already replaced the starter twice. heres the problem. sometimes the car would crank and then start up just fine. other times it would just click. if i get lucky, i can keep trying and it will crank. if it doesnt crank, i have to push start the car and it'll start up. this leads me to believe the starter is working fine. could it be a bad ground? initially, my friend thought i had a bad ignition so we wired a push start button directly to the starter to bypass it but it still does the same thing. i'm at a loss.

What year car? Got Factory Theft protection or came without?

The ground wire/cable for the starter and starter solenoid is the large black cable that comes from the battery and bolts to the engine/transmission housing (stk place was the LONG bolt that holds the starter on the transmission).

Do you KNOW where the source of power for your push button switch comes from??????????

its the 1988 10th anniversary edition. i think the stock theft protection is not working anymore. its been replaced with a clifford system. i'll have to go look at the car and double check how the cable is wired but if i remember correctly, the button is directly wired to the starter.

Sounds like a faulty starter if some ran a wire from a source other than the ignition switch to the starter solenoids trigger *blad* connector.

Put it on stands and jumper a wire from the LARGE cable on the starter solenoid to the small trigger connection on the starter solenoid. The starter should turn over each and evey time. If it does not get another starter or solenoid.

Or find the factory theft relay called the starter cut relay in the book...and jumper power from the battery positive post to the large BLACK/WHITE wire in the electrical plug that would normall attach to that relay. Starter should spin over each time you do that. IF not get another solenoid or starter with solenoid.

Normally if you'd been using the stk start system with no aftermarket pushbutton outfits I'd say the problem would lie in the ingition switch itself..........but since your using a aftermarket pushbutton switch that does not apply. But it would help if we knew where the pushbutton gets its power from. We understand one of its wires goes to the starter solenoids small blade.............but exactly where does the OTHER wire on the pushbutton get it's power from??? It might matter quite a bit.

OR for a cheap idea..........remove both wires from the pushbutton switch. Now touch both wires together and see if it turns over EACH AND EVERY time you do this. That would say a lot as to what ailes this car. Would STILL like to know where the power for the push button comes from.

There are other issues involved with bypassing the stk ignition circuit. Those can be talked about later. SF is fairly warm so those issues won't matter quite as much as someone living in Chicago or NY.
