No codes. Original issues were turn ign on, no eml or immob light. car would turn over but no spark, as battery was literally flat immob light would flash and car would start. once started eml lit up and tc light and car would only rev up by 100 rpm. leave running for an hour, turn off and wouldnt start again until battery flat to point of hardly turning over. plugged in on 5 different diagnostics systems could not connect to ecu. Pedal trick didnt work either.
By putting another ecu on now starts, revs up, all dash warning lights as should be!
Must have been problem with ecu as all works ok in that respect. Tried old one one again still no good.
Old ecu going to specialist let you know diagnosis.
Just now trying to solve fault code issues in case one was responsible for ecu failure, their are several listings across sites/forums on internet relating to throttle sensor taking out ecu on omega/vectra?
Well for a start, the Vectra never had this engine fitted to it.
So, fault codes:
0100 Mass or volume air flow circuit
0120 Throttle/PedalPosition Incorrect Ratio
0220 Throttle/pedalPosition sensor/switch "B" circuit
0300 Random/multiple cylinder misfire detected
0301 Cylinder 1 Misfire Detected
0303 Cylinder 3 Misfire Detected
0305 Cylinder 5 Misfire Detected
Your issues sound a little more fundamental to me, as many know, I dont buy into the multiple things failing at once way of thinking. If I did then I would change the ecu, coil pack, throttle sensor/unit and still have the fault.
So, what do we know, well we know that the items above are both high power jobs...i.e. gobble juice.
So I would be checking engine and ecu chassis connectiosn and supply wiring first!
As for the coil pack, its 3 seperate coils with a common 12V supply......and hence why 3 failing all at the same time does not fit the bill for me.
More investigation needed before WNPC takes over (because here on OOF we are beyond that)
Note: WNPC = Willy Nilly Part Changing
