    Diesel car went in for injector replacement, now not running at all - what are my options? 11th Sep 19 at 9:51 AM

    9 yo Toyota, 120k miles. Always professionally serviced to schedule and faultless running until earlier this year.

    Back in April we had a fault code come up relating to injectors. Our garage cleared the code (and the car appeared to run OK) and suggested we contact a local injector specialist. He listened to the car but as the codes had cleared (and not come back) he said to wait and see if it recurs.

    Same thing happened in June shortly after the alternator was replaced. He said it was probably due to that. The code cleared spontaneously after about 5 days.

    August - we get a new code to do with the DPF which our local garage renewed. Then a week or two later both the injector and DPF codes are back. Our garage sends us back to the injector specialist who, for the first time, actually takes a look. He confirms the injectors are shot and we agree to get them replaced. At this point the car is in limp mode (warning light on) but works.

    The injectors have been replaced (1300 for parts alone) but the specialist is telling us that the car is now smoking and only running for ~30 seconds at a time before cutting out. There are no fault codes. He's tried removing the exhaust and bypassing the EGR - still cuts out. The turbocharger is apparently OK.

    My original garage don't want to touch it because they say it must have been something the specialist did. The specialist is claiming that the injector replacement must have uncovered a latent fault, also that he's not a general engine mechanic so can't suggest anything other than we take it to a Toyota dealer - where it could get fixed or quite possibly condemned and either way it's going to be expensive.

    Any advice as to where to go from here? With reference to the Consumer Rights act can I compel the specialist to arrange to get another mechanic to look at it (bear in mind moving it will cost us as it won't drive any more). Or should I cut my losses and sort things out myself from here? Is the burden on him to prove that whatever's making it not run wasn't something introduced by him, or on me to prove that the problem hasn't been building up for a long time and has just been triggered by his work?

    Well for a diesel engine not to run it is either not getting any fuel or the engine managment system id shutting it down,i pressume it has the modern type injector with the wiring fitted direct to it,if the old type sounds like fuel problems OR it might be dodgy injectors.

    Get it to someone that knows what they are doing.
    Injector codes can be thrown up by dozens of unrelated problems, it only reports from the ECU any manner of sensors or switches will show up on a decent code reader not SnapOn.
    I used to get 14 codes come up 4 being injectors, that turned out to be turbo boost pressure sensor, 1 wire came out the plug and socket, cost 1 hour min labour charge.
