Could be many things....do you have fuel to the injectors?, disconnect one of the injector fuel lines and see if it pumps out diesel whilst cranking, if there is, then the next thing is the AFM (air flow meter) try cleaning this with carb cleaner (aerosol).
would i need to take it to a garage for that or can i do it myself?
funny you say that though as sometimes when i start up and drive sometimes the engine feels like all power cuts out just for a brief moment but always comes back,
although yesterday on a motor way i was accelerating to overtake a slower car and the engine revs and speed went up as yu would expext then the whole thing just cut out and died, it did this a second time when the car was slower also on the motor way at roadworks. was quite a fright to realsie your hurtling at 70mph with the dead weight of a car at your finger tips and the engine not coming on. luckily it was quiet and i got onto the hard shoulder both times. again the car coughed and spluttered and the engine turned over for a good 20 -30 seconds before ignition. at that point i just wanted to get home. today the car has worked a dream, its annoying as the fault is not consistant.
Sounding like a faulty fuel pump,I would say its easier to take it to a garage for a fuel pressure test or you will have the cost of buying the relative equipment to do it and you need to know what your doing...
not had a chnace to take car to the garage yet, however (watch me jinx this) not had the fuel pump error, i may be getting overly paranoid because some times it feels like the turbo is not kicking in, other times its fine, i think i would be just as well getting the whole then checked over lol. althought on the initial prblem, after 20-30 secs of the engine turning over it usually starts, but a lot of smoke comes out the back, so i am thinking possibly back to the AFM being the issue, although i read on another thread the the engine relay or something might be the problem? any advancements on these thoughts?
