    Vehicle : signum 1.9cdti

    Trim : elite

    Engine : 1.9cdti

    Year : 2005

    Default z19 dth not starting after new had gasket

    hello guys about 8 months ago my signum water pump seized and jumped the belt I snapped all 8 exhaust rockers so it got parked up for 3 months then I replaced

    rockers, belt , water pump, tensioner and idol wheel

    once I put it back together it wouldn't start timing looked spot on I plugged op com in and it was saying 0 faults but injection quantity was 0 over all 4 injectors

    I left the car for another 4 months and taken it to a friends garage they had it running on brake cleaner but it refused to run on diesel so I had them take the head off I had the head rebuilt and tested all was good bores look spot on no play in the pistons

    problem is it still refuses to start they found this wire broken on the ecu repaired that no difference they have checked voltage on the injectors and they are getting 3v anyone have a clue as ive spent crap loads of money and still don't have a running car

    Vehicle : vectra C sri estate auto+ hatchback auto x 2

    Trim : est sri auto hatch design auto x 2

    Engine : 1.9 cdti 150 x 3

    Year : 08/07

    Default

    I know it's far to late for a reply but having changed a head gasket on a 1.9 150 i had the same problem of no start even though the car had been running ok prior to the job just there was oil in the coolant. Anyway after ALOT of cranking the engine it finally started and it was only after doing so and thinking about why it had been reluctant to start i think i realised why. I had not primed the fuel filter as you should do after changing it, i'm sure this was the problem but i will never know for sure unless i do another headgasket.

    I have often had this issue and I have done a fair few vectra head gaskets a quick spray of brake cleaned into the top of the air box normally sorts it BUT NOT TOO MUCH
