Fill the tank that will prove if it's the split pipe problem. Otherwise disconnect the inlet pipe to the filter, place bucket undet the end, remove the fuel pump relay, apply 12 volts to the connector that has it's orientation at right angles to the others, look for fuel coming out. At least I think that's what Wammers said

disconnected the outlet pipe from filter to pump and diesel is shooting out just had it running sound turned the engine off no buzzing from the pump then started again running for about 5 mins ticking over then it cut out and now ive got a buzzing from the pump on the engine.

thanks for the info lads after all that it was a dodgey fuel pump relay changed it round for another 1 and now she running sweet again

Check arround relays 6 & 7 for signs/smells of burning, fuse box failure is a common problem

What pump on the engine, there isn't one on the engine. Unless you mean the injector pump, if your getting a buzzing check connections to fuel shutoff valve.

No it's not a big job but DO IT NOW before it causes you major and expensive grief.

New fusebox only about £150 and they seem to last about 8 - 10 years so it's not bad value. Then, if you want to do the job properly, replace all of the relays.

Not ba big job.
I took a pic of my fusebox before dismantling and kept it handy.....but that's because if there's something stupid can be done .....I'll find it.

ok but i think the problem lies in my injector pump its self
