dguy Posted June 8, 2024 Share Posted June 8, 2024 Hello... I'm a bit stumped on this one and am not sure where to turn to next other than a commercial shop. The victim is a 2011 with approximately 178,000km on it. On a recent attempt to start it, it fired once or twice then immediately stalled. Attempts to re-start it have been unsuccessful ever since. There are no stored error codes. A borescope in the oil filler hole shows that cam chain tension appears to be good and both cams are rotating normally when cranking. I've verified that it has spark, fuel pressure measured at the rail is ~42psi when priming and cranking, and all three injectors will spray fuel during cranking. Any and all advice is appreciated! Cheers, -d. Quote Link to comment Share on other sites More sharing options...

How to check is a mystery for me at the moment, one can't connect an imductive timing strobe to a coil-on-plug system. That would also suggest a cam or crank position sensor failure however either should throw an error code and there are none. Compression failure is another possibility, but on all three cylinders at once? That will be heartbreaking if it is so.

I have one of those proprietary interfaces and the associated software (can't recall either's name ATM) somewhere, it may be time to dust it off.

dguy Posted June 24, 2024 Author Share Posted June 24, 2024 I hooked up the Delphi equipment to the car this afternoon, and it's still a head-scratcher. Unless I did something wrong, live data appears to be unavailable without the engine running. No generic fault codes were available, but the engine module has "24220 - Unknown fault code" set. What this means, if anything, I have no idea. Perhaps my google-fu is lacking but I have yet to find a list of proprietary Smart DTCs and their meaning. Looks like it may be time to ship it off to someone else to look at. Quote Link to comment Share on other sites More sharing options...
Mjolinor Posted June 24, 2024 Share Posted June 24, 2024 Introduce a known fault to see if Delphi is working OK. Disconnect he brake switch or one of the ABS sensors, something like that. Quote Link to comment Share on other sites More sharing options...
