Engine cranks but won't start unless I keep it turning for almost a full minute. Then it does start reluctantly, no idle and I need to give some throttle to keep it running. After one minute at 2000 RPM both the exhaust headers were bright read. The AFR was around 12,5 when this happened.
I noticed that the rear spark plug is firing once when I stop pushing the starter button. No spark during cranking and only one when it stops cranking. On the other hand after a minute of cranking it seems to kick in as described above.
Same problem with new sparkplug and ignition coil.
No error codes at all.
Battery voltage is fine, earth connections are ok.
I don't get it :banghead:
Maybe alternator moved on crankshaft (but it's keyed!) and timing is completely off, maybe ECM broken.
