Just to give you some background, with the hope that someone could throw some light on this before I throw 5 litres of gas (petrol) inside it and strike a match, I was just driving along not fast not in boost not nothing if I was doing 40 kph that would be it and the car suddenly started tto misfire and then bog down with a rich, rich mixture (see AFR meter) I limped home and it has never improved. After reading threads on here I put it down to the phase sensor so ordered all new ones and fitted

Phase sensor with correct gap and wires in right place rotor arm lined up with line in dizzy
CPS with right gap and wiggle test on loom
Checked fuel regulator
New dizzy cap
Swopped ECU with another then swapped back
Group A coil is year old, hold ing king wire away from earth has 2 inch spark
New ECT sensor plugged into wiring but not fitted to head as its a bitch
Eliminated IGN pack as spark is so good
Taken apart all 3 wiring gubbins on firewall cleaned and put back
Fuel pump is priming OK
Changed plugs 4 times, keeps soaking them in fuel.
Suspect the rotor arm as when I pull the spark plug leads off when running I used to get a right belter now I dont plus you could get a cracking noise down in valve cover from the giant spark but dont now. Highly unlikely more than one lead would go at once. Tested leads by putting a plug in each one and watching it spark but not the brightest spark .
Pulled off injector wires and momentarily see an improvement.
Tested rotor arm with continuity meter and get only small reading, from centre to end of arm.
Changed MAP sensor


I have tested all resistances and voltages on ECU pins and find no voltage on CPS, supposed to be 2 volts (when cranking) and 0.1 volts on phase sensor (when cranking) tested ignition trigger (not that I know what that is) supposed to be at least 4.5 volts and it is 3.5 volts.

SO I THINK I AM GETTING SOMEWHERE BUT I DON'T KNOW HOW TO FIX IT . Can anyone help . Is the 2 volts created by teeth on pulley rushing past sensor or does or what. Can't think the voltage comes from ECU as it is not even in the car or plugged in for this test (as per instructions)
