Tried this little or no diesel. Checked fuel filter drained small amounts of water but mostly diesel. 12v supply going to FIP. I will renew fuel filter as it is old probably not helping.

If the engine ran before you started playing, the lift pump is supplying fuel to the injection pump and nothing else has been touched, it should run after bleeding to pump and bleeding injectors. If the lift pump relay is bridged the injection pump will self bleed after a few minutes. The only thing that then needs bleeding are the high pressure pipes to the injectors. They can only be bled as previously stated. Have you had someone playing with BECM settings?
 
A chap checked the setting with Nanacom and the syncing was fine and showed no faults. The lift pump replaced when Bridges run and supplied diesel to the injection pump.

For clarity bleeding injectors with engine cranking by cracking nuts?

I have the inlet manifold off, can I bleed with it off?

Thanks

Strange though - my lift pump doesn’t work and my FIP is obviously tired, yet I never had problem with air lock even when I completely removed the fuel rail + cut the clear pipe right off...gurgled like hell but started fine? I am used to dealing with airlocks on tractors though.
Awkward without a second person to crank for you

Hope he didn't set EDC to early or it'll never start. Open all injector pipes slightly and crank engine, as good fuel appears without air bubbles nip up. Yes you can bleed with manifold off just don't have anything loose hanging around that can be sucked into inlets..
 
I don't think so had when sprayed easy start in it fired up for 3 secs. Just want bloody thing running. I will try bleed injectors weekend with my dad see how get on.
 
After some dealing with some crinks in fuel line engine started (no easy start lots of cranking) but sounded bad and puffing out thick black smoke. Engine was revving up and down so either now engine damage or fip is faulty.

Sounds to me like someone without a clue has had the pump apart and not reassembled it correctly.

Wrong assumption pump hasn't been taken apart.

If you don't have a Nanocom i suggest you get someone who has to look at it for you. If it ran ok before, only changing the lift pump cannot cause what you have unless you have played with something else.
 
No I only changed the lift pump. The car was put back to standard in terms of omitting the power box. When Nanocom was run with both power box and standard only fault that occurred was faulty glow plug when nanocom was rerun to make sure the fault cleared. I will need to run it again see what comes up but had no luck last time. Will get in touch again run it see if we get any codes.
 
What brand lift pump did you buy???

My lift pump is shot - no fuel - doesn’t work at all! Zero mils @fuel filter ...
My engine starts first beat unless it’s hot or I go up hill for too long. Never airlocked. There’s something else.

Wammers will get to the bottom of it. Trust him and itl work.

You won't get any faults unless the engine is running. Without engine running all you will get is stored faults.
