I replaced the water separator and the fuel filter. I checked the fuel filter for damage or gunk or any kind of excessive build-up; there was none. I bled the injector pump by loosening the fuel shut off solenoid and operating the primer pump. After several pumps the pump got harder, I pumped several hundred milliliters of diesel out from around the loosened solenoid.
I tightened the solenoid valve again, then cracked one of the nuts connecting an injector rail to the injector. I cranked the engine over and even sprayed a good squeeze of ether in to the air intake before I did so. The engine gave a rough grumble for a second with the ether but promptly died and refused to start.
I have pulled off several hoses to see how far the diesel makes it when I pump the primer. I can get diesel coming in to the intake of the injector pump, I can also get diesel coming out of the return line to the tank, and I can also get it coming out around the solenoid valve when it is loosened. But no matter what I do I cannot get diesel to come out of the injector rails.
Also the first thing I did out of everything was drain about a liter of diesel out of the bottom of the tank to make sure there was not a build up of water. I have since put 15 liters of fresh diesel in there, bringing it up to around 2/3 of a tank.
So my question is broadly, why wont it start? And more specifically, why can I not get diesel to the injectors?
Thank you very much in advance, any help or advice is massively appreciated.
have the same problem?
