In need of some help with this car. It will crank but wont fire or even try toalthough I can get it to run on brake cleaner quite well, take the brakecleaner away and it stops.
There are no fault codes stored in any Modules, occasionally on extendedcranking I get P0215 Main Relay Short to Ground. I have checked that relay andwiring both with a scope & a bulb and there is no issues, we can becranking for a good while and will not always get that code.
Economy mode is displayed, however we believe that will remain until the engine starts.
We are using Autologic, KTS, Launch, Snap On & Pico tools.
Going through the data streams we have Cam/Crank Synchronisation, the vehicleis not immobilised, all temperature & pressure values are plausible....both at Ignition on and cranking. itall looks good to us and we have made comparisons to a similar vehicle. Ofcourse we cautious and understand that similar is not same.
With the lack of any direction from a DTC or a Datastream we could only guessfrom the Brake Cleaner test that we may have a fuelling issue.
I have scoped Injector 1 current, Starter Current (for TDC Reference), Cam,Crank & Fuel Rail Pressure and attach the waveforms
Any pointers and testing ideas would be much appreciated by ourselves and ourcustomer.
