Car Won't Start!

[stephenj88]

I hope that someone can help me

My 996 C2 Tip (2003) will not start.

I last drove it yesterday and took it for quite a long run. Everything seemed normal.

Today the car won't start. The symptoms are:

• When starting relays can be heard but starter motor will not turn
• Internal electrics seem OK (but had problems with windows, sun roof and rear wing opening and not shutting, also had air bag warning but all now cleared?)
• Battery volt meter is reading flat
• I have tried jump starting (battery reading in excess of 12v when connected) and starter tries to turn but no use

I guess it could either be a battery or a starter motor problem?

I could try removing the battery and charging to eliminate this as a cause but I understand that I may have issues with PCM codes if I do this??

Any help or recommendations would be greatly appreciated.

Many thanks in advance.

sounds like what happened to me a few years ago. went out on sunday, all fine. then monday, just doing my regular daily drive, I noticed the voltage was low, and had abs/psm lights, etc. managed to get home and into the garage. car would not restart. could not even jump start it. towed to indy.... replaced alternator and battery and all was good again. car had not been driven for about 2 weeks when the problem occurred. I bought a trickle charger and now put that on the car if I'm away for longer than a weekend. I did leave the car at a hotel for a long weekend last October with no problem. I plan to replace the battery approx every 2 years. good luck....

Probably the battery. How old is it? Have it tested, But this the most. Common cause of the symptoms you describe.
