Re: Diesel estate - won't start.
First thing to check is to slacken the injector pipes and see if fuel is getting there when you crank the engine, if ok then it would be wise to check the timing belt has not broken , if ok then do a compression test of the engine. Has there been any work carried out prior to it not starting , regarding the timing belt or cylinder head?

ND22 or D40 .turbo or not is not the issue .. has to be a diesel motor if you are bleeding the injectors ..do you know the pump is working and where is the fuel filter tank lines should be ok if it was running before the engine rebuild and make sure diesel is getting to the injectors at the right pressure . no resetting that I know of ... thinking on this a bit more
First thing to try with any diesel that won't start is to do a diesel system bleed. This one should be before the HP fuel rail type so start by bleeding the lift pump, then the fuel filters, then the main injector pump to lines to the injectors and lastly the injectors. Good luck.
This is not unusual on a diesel. What happens is there is air in the system. If this vehicle has an electric fuel pump loosen line where fuel enters injection pump then turn ignition key to the on position and watch for fuel to appear and then quickly tighten line before turning off key. Then try to start. If does not have electric fuel pump will need a second person. One will loosen line and watch while other cranks vehicle until you get fuel and tighten line before the other person releases ignition switch unless vehicle starts first. If that doesn't do the job do this where line hooks onto each injector. Probably will not have to do this to all injectors but could run rough until all the air gets out of everything. I have farmed with diesel tractor for 25 years and dad I drove the gm vehicles with the 5.7. You normally don't start a diesel without bleeding the air out of the lines although some will self bleed most won't. Hope this does the trick.
loosen one fuel line to one of the injectors, try to start the truck and look for the fuel to spray out of the line. it should spray rather hard if the injector pump is working right. if it just dribbles or trickles out you have a weak pump.
dear . you have water mix with diesel . dont start again . replace diesel filter connect fuel from out side , if you find injector cleaner try use it , after replace fuel filter try to put 50mm engine oil in fuel line . for lubricate and remove rusty.
it can also be an injector. injectors tend to supply more diesel after long service. To check if this is the problem: let the motor idle whilst it knocks. start from the front of the motor- loosen no1 injector fuel line- the motor will start idling roughly as fuel supply to no1 piston is starved. If the knock persists, tighten the fuel line and move to no2 injector and repeat the process. the knock will gradually go away if one of the injectors' fuel lines are loosened and the injector is faulty. If you get 1 or more injectors with these symptoms, remove and replace the injector. If the problem persists, it can either be that one of the diesel pump plungers are worn and supplies too much fuel or a big end bearing is faulty. RegarsCarel de BeerSouth Africa
Unfortunately diesel leaves a residue in the lines and on the injectors.
There is only one cure for this, take out the injectors and get them serviced and flush all the fuel lines out with clean gasoline.
