bleed screw not bleeding

[peter.j]

hi i have a series 3 diesel land rover  it ran 3 to months ago for hrs parked it up as is normal with this l rover as its only really used 1 a year for chain harrowing  and running about the farm doing little bits  it starts every time no matter how cold it is put a good battery on it it goes only this time it didn't i have checked the fuel up to the injector pump and all is flowing great i took the check valve and filter out of the pump all well and good  but no fuel comes out of the bleeders .on trying it to start this time it ran for 10 -15 seconds then stopped like it ran out of fuel any ideas whats become stuck or is gone in the pump please

Not been on  here  for a while, Just saw your post.. trust you've sorted the problem?

Leaving the thing parked for months can cause the metering valve inside the CAV Injector pump to stick shut, regardless if the stop cable is in the run position of not.

There's only the light governor spring to push it back. The metering valve is meant to float in its locating hole, often gets tarnish on it and sticks in the closed/OFF position. Then no fuel get into the high pressure side of the pump. 

You could try wiggling the stop lever arm on the pump back forth... but Remove pump, and partial strip down/clean of the stop lever side best.

Oops , missed this too 

Make sure the stop lever on the IP is fully off (down) 

Check fuel flow to feed into IP 

The main bleed screw on the round section of the IP is the one to concentrate on . Open it and crank it for short periods until diesel comes out . 

Tighten up then loosen one injector pipe nut at an injector and repeat cranking for short periods while holding the throttle fully open until it fires 

Hope that helps
