Help! What have I done to my Cayman 987.1

Hi all,

In need of some help please!

As we've all got a bit more time on our hands with lock down, I thought I'd buy a borescope to have a look inside my engine. Pleased to report all looked well, but...

When I put everything back together my 2006 Cayman S manual won't start! Video below showing what happens but in summary it: makes a clicking sound, gives a PASM failure alert, gives PSM failure alert and the driver side window starts going down! What on earth have I done!

To be really clear in what I did, I...

1. Jacked up the car, removed the passenger side rear wheel and two internal wheel arch covers.
2. Unplugged the coil packs on cylinders 5 & 6
3. Unscrewed the coil packs on 5 & 6 and removed them
4. Unscrewed the spark plugs, had a peer inside with my camera
5 I then realised pistons 5 & 6 had come to rest near the end of the cylinder so I couldn't see much of the cylinder wall which was what I wanted to look at, so i put everything together and went to start the engine. At this point it turned over a few times but didn't start (it normally starts first time every time) but I didn't think much of it.
6 I then took coil packs and spark plugs out of 5 & 6 to have another look now the pistons had moved.
7 Then I put it all back together and am now stuck with it not starting as shown in the video

Any help is very much appreciated!!

Thanks in advance,

Jon
 
Im no mechanic but sounds like a dead battery to me - i would suggest that would be the first thing to check .Good luck

 
Jon,

I'd agree with Adrian on that. I think a battery charge or a battery jumper is your first port of call.

Unfortunately, I've no explanation for what's happened.

Hi both,

Thanks for the advice. Just to update this thread incase it helps anyone else... it was indeed a dead battery. Must have drained it whilst working on the car with the door open. After a bit of Googling, apparently these cars can 'do some odd things' when the batteries are low!

I have just jumped it from my wife's car and all is fine again! Going to put the battery on charge now.

Thanks again all,

Jon

 
Jon,

If you've not been using the car very much lately the battery was probably in a low state if all it took was to leave a door open for a while. You may want to think about buying a replacement battery?

Amongst other random things, the dash panel lighting up like a Christmas tree is always a good sign of battery problems.
