I know the car will run with the air tube uncoupled once started, but will it start with the electrical plug unplugged?
I've spent hours now probing and am finding nothing wrong. All continuities that I've tried, inc the crank posn sensor to ECU plug, earth straps, earths from ECU plug, all OK.
The ECU seems to be choosing to not run the relay during starting. I've measured that it powered up the coils, etc, probably the fuel pump, for about 1 second then shuts them off, as I presume it supposed to during the key on 1st or 2nd position.
But then does not supply again when turning over with the starter with the key on 3rd posn. It's as if the ECU doesn't know the engine is turning.
200 miles old Magneti Marelli Crank sensor from Eurocarparts that I fitted only a few weeks ago. it does measure 1k Ohms though, instead of the 600 of the original.
Car was running very well, just cut out the dual carriage way at 40mph and won't re-start.
Thanks.
