My 1991 944S2 has been stored for a few months and I just recently replaced the cam chain tensioner. When I connected the battery and tried to start the engine, all I get is one loud click from the engine area in front of the windshield. The engine doesn't turn at all. I do see the dash lights on like with a normal start. After one click, I get nothing until I remove the key and try all over.
I tried jump starting it with another running vehicle but got exactly the same behavior.
One other detail is that when I reconnected the battery and locked the vehicle, I got around twenty fast flashes from the lock LED, then one flash about every three seconds. That seems more frequent than before I started this work.
I'm stuck. What would you investigate to fix this?
thanks,

You might have a alarm problem but before we go down that road, did you turn the engine over a few time by hand to make sure that the valves and pistons are not running into each other?

Sounds like a very dead battery to me. Fully charge the battery and make sure none of the cells are dead. If the battery is completely flat, it may not crank over on a jump.

These cars do not like to be jumped and they need a lot of power to crank. Try to slow charge the battery.

Guess I'm with the guys who are saying "battery". I couldn't believe this myself but I had a Nissan 4X4 that was running fine, then the next moment would not start. Tried jumping the battery--nothing. I thought I had other problems until a new battery was suggested. Put it in and BINGO, problem solved. I still am not sure why the battery just died without warning nor do I understand why jumpering it failed. All I know is that I'm glad I didn't start looking at a hundred other things that were OK and thinking the battery was allright.
