Okay , set up to have a crack at sorting things out this morning.
First off took off the Injection Module and found that it was oiled up a touch inbetween the plates AND on the connecting plug , a good spot of oil in there !
So ... theres still a bit of the paste thats use to meet both surfaces of the module to the dizzy so i clean up the oil , like most CVH engines its a touch " sweaty " with some oil ( not a horror picture lol ).
Im thinking that oil is NON CONDUCTABLE ? so perhaps this oil is causing the car not to start on occasions , the plug in particular was pretty heavy wtih oil so ... along those lines after cleaning up i try starting it from cold.
Fired up ok , gave it 1 minute , fired it up again ... repeated this 10 times to check for any problems from starting cold ... and it started everytime.
After this ive taken it for a run for some petrol as im down to 1/4 a tank , nice 40 min drive there and back ( also help charge the battery after all the cold starts ) , then tried starting the same procedure again , but obviously this time with a hot engine.
Tried this around 5-6 without a problem ...
So i guess its safe to presume that the oil in the joining plate on the Modulator and the plug wernt helping.
Ill give it a week and see how it goes , but so far the signs are good.
