[Vwdiesel] More Quantum Questions?

[mark shepherd]

Very good point Rudy. Especially on an older/lower compression engine. Funy 
how some engines suffer from this more than others.

Bill, after you next manage to start the 'Q', and if it fails to restart 
after being switched off for a few minutes, then use a jump start lead from 
positive of battery, directly onto the glowplug rail, then run to the cab 
and try starting again.
When started, remove clamp...

If this does the trick, then the solution is to remove g/p relay sensor 
lead, from sender on back of head. Red and yellow I believe it is....
