    So do we think the injectors are ok if she runs fine? thanks

    If the vehicle is running ok, no misfireing and no black smoke, then the injectors are ok, if the injectors where not operating correct, you would have rough running.

Sounds like the diesel return pipe to the tank is blocked or restricted . This is a low pressure pipe return, if blocked you are getting a pressure build up and the pipe blows off.

Non start

if it runs after using easy start there is no air in the system. There will b e a problem with the tips of the injectors and they will need replacing. Cranking speed is essential to diesel starting and I suspect that there are glo plugs or a pre heat system for the diesel that is not working properly

By the way using items like easy start is the ideal way to blow a diesel engine up as they are a compression ignition engine and when the compression gets to a high enough temperature it will ignite the easy start when the piston is half way up the stroke causing the piston to bend the con rods or break crankshafts

A better idea is to fix the problem correctly as it will be cheaper in the long run.

Where is the fuel regulator kia sedona

check the turbo for failure and check the intercooler for cracks and leaks . check the hose clamps . have the tips of the injectors cleaned / replaced and if you want to blow the engine continue to use easy start. Diesels are compression ignition engines and that means the air is white hot at the point of injection of the diesel and any fuel substance introduced will spontaneous ignite and bend con-rods and crack pistons.

thoroughly clean area around injectors,and then blow with compressed air so no bits will fall in the holes when injectors removed.loosen main injector pipe nut,remove return fuel line,dont lose copper washers,put special fuel bolts back in top of injector firm[by hand] undo holding down bolts evenly,undo fully injector pipe nut,.gently pry injector loose,and remove,making sure sealing washer at bottom also comes out..while I dont specifically know this particular engine,this guide applies to most diesel motors.I have rebuilt a 6v72 detroit motor,yrs ago.Assembly is reversal.may need to crank over to bleed diesel at injector,always use new sealing washers.

Yes big time ,fit a non return valve in the feed line from the filter to the pump ,you have a air leak somewhere and i would suspect the rubber o ring in the top of the filter housing,its running back when you leave it because of the air leak
