Took the car for service 2 weeks ago no problems drive it home and put it in the garage today being nice take the cover off. nothing turns over but no spark changed the dme relay just incase but nothing in the time I have had her never ever as she not started first time any ideas and any one fancy coming to see if they can help or might know what it might be I've been told it might be the immobiliser but can I find the control box can I XXXX.HELP.

Have you checked for a flat battery??

That was going to be my suggestion but I assumed he'd checked that.

My S2 runs it flat after a couple of weeks if not used.

same with mine 2 weeks of no use and flat battery, mine lives with a life support now (aka trickle charger)

Guys it turns over and over but no spark .Battery fully charged.

So have you got power to the coil? Is the coil good?

Yes I like you thought of the coil just that when I spoke to the garage he said they are pritty bomb proof and don't usualy just go I said what about the HT lead he comments were again it would show up earlier missing etc not just go he was pritty sure it was the imobilser just need to know how to get around it come that even blossdy find it.

hi greg speak to prev owner and find out where immob fitted and give then a ring, i know you say no spark but dme relay is also favourite non start problem

Hi,
With my immobilser you won't get any lights up, let alone be able to turn it over. Maybe yours is different? perhaps others could shed light on that.
Have you checked the rotor arm hasn't come loose?

Hi,

First thing have you got a multi meter ?...Test for +12VOLTS on the + terminal of the coil.IGN on and immobiliser turned off !!do you get any confimation that the imo is off..e.g a change of state on the LED ? a ping or ??/ what make is it ?? Note:- (Bosch coils sometimes are marked with a no 15 to denote the + terminal0...if no voltage present then i would suspect the immobiliser.....have you got fuel does the pump run ??.on the majority of 944 the imo ecu is mounted next the engine ecu under the wooden kick panel in the passenger footwell,,,the "cuts" for the actual circuits coil/ign fuel pump are again frquently done in the fuse box wiring above and in the fuse box area..pm me if you need any advice..i'm an auto-electrician and would be pleased to help.

cheers

any progress ?

Seems like the crank sensors.
