Grab yourself a jumplead - preferably a normal car jump start one.Originally Posted by Tony777
Carefully clip one end to the head of a glow plug
Get an assistant in the car ready to crank it over
Connect the other end of the jump lead to the remote jump start point under the bonnet - it'll spark badly at 80 ish amps, but so long as your jump lead at the other end is touching ONLY the electrical glow connection you'll be fine.
Count to 10 and then try cranking the car.
As Barney rightly says, check the clear hose between the filter and injection pump.
If the tank's under 50% and the injection pump is de-primed - it can take upto about 2 minutes of cranking to get the car to start. Check your injector leak-back hoses for cracks, and there's various other bits that can cause it to de-prime.
When did it last run?
Your glow plug relay is in the E-box on the turbo side of the engine - it's the unit between all the ECUs with the bigger wires running to/from.
