S4s hot starting problem.

[Vulcan Grey]

Nick,

 

Go back to simplest things first.  When the car is warm and won't start, remove the gas caps and try restarting it.  Do you hear a lot of pressure being released?

Already tried that Travis when you suggested it way back in this thread-makes no difference

When the engine is in its 'no starting' mode have you whipped a plug out to see if its wet?  If it is wet then that would indicate a lack of spark .

 

Have you tried removing plug cap and using a spare sparkplug  rest it on the engine(insulated grips might be an idea here), crank it and seeing  if you have a spark?
