VR6 won't fire up, any ideas???

Recommended Posts

This morning my vr6 refused to start with no warning, turns over but no spark at all, AA man came and checked every thing and found i've got power to the coil pack and injectors but no switching signal. he said first thing to check is the crank case sender which i have now ordered and hope to recieve in next couple of days.

 

anyone one else had similar problems? anything else i should be checking? if it's an ECU problem what's it likely to involve?? any ideas would be much appreciated!!

Immobiliser? ECU relays? Crank case sender is a very expensive "suck it and see" first try ..

i'll certainly have a look at the relays, went for the sender first as it's what the AA man thought it was most likely to be and it was an easy job i could do myself. fingers crossed it is something that simple as things tend to get expensive quickly with the vr6's!! thanks for your help!

Always start at the bottom. Engine speed sensor? £140. ECU relay? £9.

As we keep saying over and over and over again, the VR6 will always report "engine speed sensor" failure in it's diags mode if the engine isn't running. That is why the RAC and others (who know no better) always have you throwing money away on VR6s that won't start.

adamukcorrado,

 

Question from the very mechanically dumb.....

 

What relays did you clean, and where were they?!!!

 

:scratch:
