VEHICLE STARTS FINE BUT I HAVE TO MANUALLY PRIME THE FUEL AND WAIT FOR ABOUT 15 MINS FOR IT TO WARM UP,OTHERWISE JUST AFTER STARTING SHE WILL CUT OUT AS IF SHE IS STARVED OF FUEL! MITSUBISHI DELICA 2.8 TDI AUTO

I would check your coolant temperature sensor this sensor has some control to your air/ fuel mixture

Hi
Are you sure that's not a 'safety feature' to warn others that you're reversing - like on commercial trucks?

Also, why do you let it warm up for 10-15 mins? Seems excessive? Is this suggested in the Owner's Manual for that engine? As this is surely fuel injected, it should be ready to go immediately....or wait ~5 minutes if you're going full throttle from the dock/launch...to let the oil warm a bit.

Fuel pump going out. Once it gets warm after 15 mins the o rings loosen up and cause it to loose prime and shut off. After cooling for 15 mins they have shrunk enough to build pressure again.

Has anyone checked fuel pressure cold and hot ? Check engine light on ?

Coilpacks or possibly crank sensor, also check to see if fuel system is bleeding air while vehicle is off

Fuel filters don't typically clog from a vehicle sitting.My 1st guess would be the fuel pump(motor sitting stationary has made a contact on the armature corrode).Try thumping the fuel tank with a rubber mallet while someone turns the key on to prime the pump(turn to run,wait 5 seconds,shut off,wait 15 seconds,repeat).This might get the pump moving again.

Fuel system needs work, replace fuel filter and fuel pump go Check out Autozone they got the Stuff.

Do you mean 8 to 10 seconds to START? Turn over means the engine is turning or cranking BUT starting is when the engine is actually running. I think you might have a fuel problem like your loosing your prime. Turn the key off wait 15 sec. then turn the key ON not cranking it repeat this (3x) if the car starts immediatedly your fuel pump is loosing its prime or the fuel pressure regulator is leaking.

replace fuel pump and relay.

Have your battery checked.
