VR6 WARM START ISSUE CUTS OUT

[francoisd2446]

Have a mk3 vr6 aaa engine code wont start when warm starts first time when cold and will run all the time, really need some help guys, love the car but it will go if can't fix I am fed up of it, no one can pinpoint the issue, one said it is immob issue but then if so why would it start first time?
Reading a lot about thermostat going to try next.
I also can't get the vag com to communicate only thing it can find is the abs and that is it, I need fantics help please......

have you tried the throttlebody

[DubAndDubber]

try doing a search buddy this has been covered thousands of times.

[francoisd2446]

how does the throttle body affect the warm start ?
Will do more searches but so far found could be the coolant temp sensor....

[DubAndDubber]

throttle body wouldnt affect it, if its cutting out when warm then usually its EMCS, engine management coolant sensor. Thermostat wouldnt affect the non starting issue either.

Thanks DubandDuber the ECMS is that the blue sensor (or what they call the temperature sender unit (run on)? I bought one today and going to try tommorow.

Johnyvr6 thanks for you advice also, I will hopefully have an update tommorow so let you guys know.
Would also really aprreciate it if you guys throw some more idea's my way if the blue sensor don;lt fix it.

I was thinking maybe to test the fuel pressure would that cause this effect ?
Also I bought a sensor for this engine but can't seem to find where it goes it they told me when I bought it for the aaa engine there is only one sensor could be the cam position sensor or hall sender, it has a plug to connect somewhere and a prong at the end with one bolt on it, guess this would be for the timing but can't see on top of engine so going to look underneath.Any idea's ?

ok changed the blue coolant sensor this morning and won't even start cold
now.

All I can here is one of the fuel injectors consistently running...headache now...the car trys to start revs a bit high then just cuts out.with the key turned to position one I see the oil light flag then stop flashing is that also normal ?
