Immobiliser problem? - 2.7 Boxster 2003

[PigMi]

Hi,

Im building a Porsche powered Classic mini and I am having problems with starting the engine. The problem actually started on the donor vehicle as the last time I tried to move it under its own power it would start and stupidly I put it down to old fuel/spark plugs etc...

Im now at a stage where the whole wiring loom is in the mini as well as pretty much all the modules being attached. We have attached the OBD and it didn't show any problems, the key is being read, the M534 is communicating with the key, but we do not have the spark or fuel pump.

I took the ECU to one person I know, but he was unable to reprogram it and then a friend who is knowledgeable with ECU's has tried to bypass directly in the ECU the immobiliser but this hasn't changed anything, the engine cranks over without a problem but no spark or fuel.

My question is that I have read that there are a lot of problems with the M534, is this probably the case to? Or are there any other failsafes that stop the ignition and fuel?

Any help would be much appreciated!
