Isuzu trooper hard to start

and glow plugs are off , hot.
so no fuel
ever check filters. fuel.
try test fuel it will run for 3 seconds.. proving , lost fuel.

indicates a fuel supply and pressure problem
check and bleed the system
have the injectors professionally overhauled by a diesel specialist shop

Is it diesel or petrol

This engine 'loves' glow plugs! One goes and the others try to handle the amps. Change them and you will have no probs! Other than that, I feel this is about the best diesel truck made!

It sounds like the fuel is gelled, is it cold where you are and what are running for fuel? If your in freezing weather you should be running blended fuel, straight No.2 will gel at about 25 degrees (F). Take a hair dryer or heat gun and warm the fuel filter up. Or if you can get in warm garage and get it started thin the diesel with kerosene, about 2 gallons to 20 gallons of diesel. Then drive it for at least five miles so the kerosene gets circulated through the system. I've used gasoline to do this too, but only use about 1 gallon to 20 gallons of diesel.

Can I fit a 3ltr turbo isuzu engine to my 2000 model holden rodeo it is fitted with a 3.2 ltr V6 at the moment

Hello, it is possible that the pump is going bad but, it sounds more like water in the fuel or a dirty filter or dirty injectors. I would try a fuel additive first to see if that will clear your problem. Let me know if you need any help. Good luck.

cant start deisel 3.0 lilter sounds like there is no fuel getting to the engine

Was it lined up right as the trigger point for the sensor is important.Is the fly wheel fitted one position only that the bolt holes line up or will it fit no matter which position it bolts up Line up the flywheel trigger with the sensor after you have put the engine to Top Dead Centre.Put at tdc and see if the trigger and sensor are together.
