No fuel to injectors
No fuel to injectors
- Fitted the correct relief valve
- Added a pressure gauge to the pump input banjo - i see pulses of pressure but not a constant 0.8 bar, it leaks away when i stop pumping.
- Dismantled the lift pump, looks ok.
- Fitted my spare lift pump (known working engine)
- Changed the relief valve for another (known working)
- Changed the fuel filter housing for another (known working)
- Its all primed, no air. I have a priming pump/prefilter before the lift pump. With that i can get it up to 0.8 bar it drains by the relief valve, but when i stop pumping it drops.
- I popped a deliver valve out and do get fuel when priming it.
And never any output from the open delivery valves.
Any ideas?
Ok this is driving me nuts...
