    Last night on my way back home my engine cut out and then 2-3 seconds later it cut back in and kept going. Anyone have a clue to this mystery. The engine light came on for a second and then went off again. Only code is 31, which should have no affect on operation. It didn't even cut out enough to stop the car rolling. Fuel pump is relatively new, Delphi CAS is also less than 2 years old. It has completely stalled twice before but I was able to start it straight back up.

    TPS is relatively new Delphi. Solenoids are also fairly new AC Delco units. Seems to have the occasional miss on idle but doesn't miss under load, so not sure if that is related or not.

    I have run codes and 46 comes up now. RACT got me going but he doesn't know what helped he tried a few things all at the same time, before he got me to crank the engine.

    Hi mate
    as you have done the CAS Id be playing with the plug that go's into the dfi module also the lead thats on the cas...next time it happens give em all a bit of a wiggle and if it starts it will be one of those...the VX did this sort of thing for a while till I replaced the dfi module, cleaned all the pins/sockets on the plug and sprayed contact cleaner on the cas plug...ran fine till it was written off just before xmas :)

    Cool thanks Wozza. I will get some contact cleaner from Jaycar tomorrow and clean the DFI plug and also squirt some RP7 on it. DFI was my thinking, CAS wouldn't be old enough to have cracked yet. I think I mentioned it has a slight miss on idle and I don't think a CAS would cause a miss, more so just stop dead, like it did this arvo.

    Thanks Lex, I too hope I can sort it soon. No way I want to block traffic again on a fairly busy road. I was just fortunate it didn't happen on the Bunning's intersection. That road is insanely busy and I drive past it quite a bit. I thought I was going home in a flatbed this arvo.

    Looked up your code 46. To do with cas. 46 Crank angle reference signal (engine will not start).
    So maybe wiring, plugs, or a dud cas sensor.
    Look at plugs & wiring first.

    Ohhh that sux I don't have a tool to remove the balancer. Hopefully it's just a plug. I have found Delphi sensors are no longer as reliable as they used to be. So it could well be a dud CAS.

    Ive had dud dfi before. Code scan showed a lot numbers basically referring to the cas.
    Nothing to do with cas. It was dfi.

    It definitely has miss on idle. I suspect it is related.

    I'm thinking it might pay to order a new DFI next week and fit it regardless. No idea how old the unit is that I have in the car at the present. Plus this miss is fairly new and I really think it's either coil or DFI related.

    I have a link to some high voltage Gorst coils at $100 a set inc del, might order those next week as well. I have read people having issues with the plug. Wondering if I need to book it in and have the plug checked out before I start fitting new parts? I wouldn't know how to test the plug other than clean it, squirt some RP7 on the contacts and refit it.
