hi guys i have an escort van x reg 1.8 non turbo diesel, it was a great starter until i let my friend start it, it started and conked out, ever since it hasnt started, it will tow start and im getting diesel to the injectors when cracking off the injector pipes, ive tested all the glow plugs individually and there glowing but i dont seem to have power to them,im getting the glow plug relay click, i have tried putting a wire to the 8mm bolt at the start of the glow plugs from the battery and holding the glow plug onto the engine this heated up the plug so im guessing the wires are ok on the plugs, anyone any ideas it was fine and this suddenly happened
