OK so it still won't start.

Pretty convinced that it's the immobiliser and Mal has offered to get that sorted if required.

I've read that the BEM can forget who it is if disconnected from the powerd for long periods. Now I find that hard to believe, but this car has been off the battery for a long time (at least 3 months).

Can anyone cormfirm or deny this.

New Key has been coded to car and old key has been found, neither make it run.

I'm not convinced that the fuel pump is working, is there a way to test it?

How can I check the injector pulse (test light/multimeter)?

Also WTF is the ECU? I can find the BEM easily enough (had it out and covers off, butit looks OK, no obvious burnouts on the board).

I used a mates LAUNCH CReaderV, but it wouldn't talk to the ECU to give me any codes. I've heard that you can earth part of the diagnostic connector and something will flash to indicate the fault code, is this true? and if so how is it done?

Thanks in advance and happy valentines day<3, though I'm rapidly falling out of love with this car.

yes you can earth out the connector . Simply earth out the number one pin which which is on the left hand side on the wider part of the connector once earthed turn the ignition on the engine light will flash with long and short flashes. The codes will take to long to type but they are also in the Hayes manual for the car too

Forget codes and that BS just for now, will be pointless

Start off getting yourself a noid light from repco or similar, this is used to test the injector pulse, is a low watt globe that fits into the injector plug, if you have injector pulse then your immob is fine, if not then you start looking

Second tes assuming no pulse, check for spart, if there is no spark either most likely the CAS. If is spark but no injector pulse most likely immob at that point

To test fuel pressure, you dont have the fuel pump short pin on the TH I dont think from memory but you can power up the pump by turning on ig and cranking, the fuel pump should pulse as the car is trying to start
