I think the sensor head screws off, the fitting on the slide hammer loosens it but the frame of the oil filler cap is in way unscrewing the first injector.
Just to note brought the car for 200 mile drive to Cork today with work and never sounded better, but getting it to start was hassle. Had to get mate to jump start, after about 6 attempts came to life. Battery is 10 years old so bought new one today for the long trip (with old fully charged in the boot!).
I get the feeling it must be the glow plugs, so will do a resistance test when I get back to Dublin. Do you have any photos to show how to test the glow plugs with a voltmeter?
Many thanks Artic,
