I found the problem with the car smelling of exhaust fumes, that I posted earlier, it was 2 injectors leaking i could hear a high compessed leaking air sound coming from the engine and located it to the injector, and I found a pool of what looks like diesel at the bottom of the injector. The problem starts from there on, as I went to remove the wet injectors, I un did the 2 alan screws that held the injectors in place and before that I unclipped the lead and the fuel pie that goes to the injector. Unfortuanetly the injector would not budge it was solid, I did use reasonable measures without damaging the injector, but to no avail, I therefore proceeded to put it all back together to take it to the garage for the experts to sort out. On completion I started the car up it ran for about 5 seconds then cut out, and now will not start up at all, I did not lose any diesel or pressure when I undid the fuel pipe that connects to the injector so that would rule out it need bleeding. In the meantime I have disconnected the battery and hope it resets itself, other than that I'm at a loss, what have I done wrong? please anyone can you please advise me? I'm all eyes and ears!!!!
