[Vwdiesel] Analyzing compression numbers - oil in injector hole?

[mark shepherd]

I think pulling the sensor wire from the coolant will do it; but then you 
always get the full cycle.
In my one 'Q' I had the relay wired up in the engine compartment and powered 
the relay via a spare switch on the instrument panel. I could then switch 
the relay off after I started the car, leaving it gave the full cycle.
Off then back on gives a new cycle.

Leaving switch off when parked made it steal proof[ish]

I also had [still have ;o) ] a light bulb to the glowplug bus bar to see the 
truth...

Mine does not give me 7 seconds of glow, so how do i over ride the coolant 
sensor, disconnect the lead. it starts with min turns when cold and 
immediatly after shut off though in that inbetween range it can take several 
cranks to get going again.
Oh, it is a 1.9 idi engine though in a 91 jetta.
