issues whilst starting.

sometimes on my 2.0 16v my car wont start. it fires but doesnt seem to turn over fully, then it will start. cant be a starter problem, doesnt seem to be a battery problem and had all sensors changed with no difference. any advice for a decent mechanic to do the work myself?

might be your ICV (idle control valve) may need cleaning

but im sure a tec will be along soon to help some more

its got a new ICV on it. cant be that.

Most likely the battery starting to die - you got a multimeter?

yes. im a mechanic. perfect voltage at start and during running. also swapped that out.

coil packs?

Could be blocked injectors?

recently cleaned so cant be that

TDC sensor, would tie in with the symptoms.

And I have one for sale

Top dead centre sensor was the first sensor to be replaced.

Intermittent immobiliser fault perhaps, I’m clutching at straws really, best thing is to get connected and read live data etc.

Immobiliser fault is what i would be looking for what year is it?

From my understanding its not cranking properly? if thats the case i'd be looking at current draw from the starter. then check earths.
