Probably the relay on the electric warm up is dodgy try "CAREFULY" putting a thick piece of wire from the top of one of your glow plugs to the possitive + terminal on your battery for about 12 seconds "MAKE SURE THE WIRE DOESNT TOUCH ANYTHING ELSE THO" then remove wire and turn the key straight away!
the car should fire up
