Need help please guys - I've installed a 1997 M3 Evo engine into a 1996 Compact with everything from the donor car - engine wiring harness, EWS, evn the ignition and door locks, etc etc.
The project has progressed to a point where it should run but I have no spark.
The key turns the engine ok and the central locking works with the key fob. From what I can find on the web is that if the starter engages then the EWS is ok. Its the interface with the DME that I'm not sure about. I understand a single wire sends the ISN to the DME.
Does anyone know if the starting circuit is seperate from the DME's injection and fueling circuit? Will the engine turn without the DME activated?
Any suggestions or thoughts please on where I should start??
How good are the eBay diagnostic tools selling for £75 ish?
Thanks for your help!!
