L200 TD2.5 Year 2000 Forlife.

Would anyone be able to tell me if there is a fuel pump relay fitted to the above vehicle and if there is where exactly it is located please?
The problem I have is what "appears" to be an intermittent fuel/starting problem -
Starts and runs fine from cold or warm 90% of the time but on odd occasions once stopped, will turn over fine but will not fire suggesting no fuel from pump.
If left for a period ie half an hour/one hour or overnight will start fine again.
Any ideas welcomed!

give it a try mate could be air in the fuel line or fuel draining back to tank if you have a soft one then you have a problem check the simple things before going electrical

yours will be a non fbw truck the pumps are different

Check there is full voltage goin to the electric diesel stop on the pump. I've also heard before of the diesel stop becoming sticky. I think you can disassemble it and give it a clean.

Fly By Wire ...if you have it , it mean you don't have an actual throttle cable, all done by sensors and electrickery

@LezT @123hotchef ^^^^^^^

It's on the back of the fuel pump, round nut like thing (24mm) with a single wire terminal on top, normally held with an 8mm nut.

Did ya try the primer mate?

Will look into it a bit more tomorrow when I have more light.
Thanks for the info ref the "diesel stop" & the diagram, I might be able to get my head around it.
Started/stopped it several times today when hot with no problems hence not tried the primer.
Do I assume there "is" a relay controlling the diesel stop? If there is one fitted where would I find it?

not sure about the pre fbw wire ones i can check the electric diagrams but I would try the primer first

u can also check solenoid on pump with a meter when it dont start to check it has 12v to it, you can also hear it clicking when u turn the ignition on

Pic is of an FBW Pump so not much help @Hound Dog , can we have the pre FBW on ....Thanks.

Stop solenoid or ECM relay is my bet, sounds like stop solenoid through, £10 fix

Most motor factors will get you one, try Euro car parts but phone or go in as there web prices are stupid, alternatively try eBay or milners
