Please help! I have a 1999 Porsche 996 C-2 Coupe. It has just over 100,000 miles. When I try to start the car, it does not start. I have tracked back to the starter. I am getting current, but I do not get 12v to the solenoid when I turn the key. I hear the fuel pump prime. All the dash warning lights come on. All electrical work properly, but the starter will not turn and the engine will not fire. I have checked EVERY SINGLE fuse. I even tested with meter for continuity (sometimes a fuse will not look broken even when it is). I also checked and cleaned the ground strap on the passenger side of the engine. All the contacts (engine ground, starter and alternator) look clean and free of corrosion. Should I look for a starter relay to test? How is this done? What about the clutch pedal switch? Does anyone know how to check or jump the clutch pedal switch? Is there anything I am missing? Here is the history. Last summer, the car would start VERY VERY slowly once it was warm. As I understand, heat causes resistance, and after you drive the car for some distance, restarting can really stress an old starter or appear from a poor ground strap. This winter, I attempted to start the car in the cold. It started fine. Upon restart, it wouldn’t turn over enough to start the car. I had the car started with the aid of jumper cables, and I drove it to Auto Zone. Battery was charged and tested…passed with flying colors. Drove car home. Next day, car started but wouldn’t restart. It was the SAME THING, so we jumped it and I drove it home. Next day, I removed and cleaned the ground strap. Retested it….car started but wouldn’t restart 20 minutes later. Then I removed the starter and alternator. Both were bench tested. Both passed all tests. I bought a starter anyway. After install, the car will not turn over AT ALL. I removed the new starter and took it back to Auto Zone to bench test. It engaged and started spinning and passed all tests. Then I put it back in the car and found 12v not going to the solenoid. So I bought a new ignition switch and installed that. I am still not getting any power to the solenoid. Please help me get this baby running.
