Right, back to where this topic should be now.

Did the car have a virginised ecu fitted and programmed with a T4? Or did it simply have an ECU kit fitted?

Do you have the oil pressure light lit up when the ignition is switched on? When you say it won't start does the engine turn over but not fire? It could be that the ECU issue has been resolved but there is a further issue with fuel pressure.

If the oil pressure light illuminates and it turns over they need live data to check the fuel pressures, if they are OK and the cam and crank sensor are also reporting the correct RPM then it could be injector leakback that is causing an issue.
