2.25 diesel just will not start.

Big Mat · Apr 30, 2013

I also intend on sending Craddocks the bill for the work on the pump, seen as they sold me it as a recon unit 6 weeks ago!

mat, would you mind doing me a favour. Would you take a picture of your spill rail (esp no4 area) and the fuel lines and where they go. to the filter, etc.

I noticed something a little odd with my setup the other day, and I think the PO has done something funky. Well I know he has.. as my 2.25 is in a 110

Big Mat · Apr 30, 2013

I havent got the injectors fitted so a picture wont help, but i'll try to explain.

The spill rail attatches to all 4 injectors, on the 4th injector a pipe attatches to the top which then goes to the top of the fuel filter.

A pipe attatches to the end of the spill rail and goes to the fuel tank ( i think ).

What year is your 110? 2.25 was fitted in the early days of 110 ( 85/86 i think )

I've had the pump and the injectors tested.

The injectors needed new nozzles, they said they were completley destroyed. I managed to source another set so i've got a full set of injectors that have been reconned and tested to make sure they work.

When they tried to test the pump, they said they had to tighten everything up inside as it was barley done up, finger tight at most they said. But once they tightened everything up properly it tested fine.

So i should have them back tomorrow and then its a case of rebuilding it all again.

I do want to find a fuel pipe, the one that goes from the tank ( mines a 109 with the rear tank ) up to the lift pump because mine has a dodgey extension on it and i'd prefer a new one, but i cant seem to find one anywhere. Does anyone know who stocks them?

Sounds like youre getting somewhere with that now, mate! Unless you get em tested properly you've no idea whats going on. Should be quick to refit sounds like you've had a bit of practice by now.

Best of luck it will be worth it.

c reg, but it has a 2.5na wiring loom and lots of iffy wiring

I bought it when i was new to landies and thought it was a 2.5na

I need to go out and have a peek, but i think someone has attached the spill rail to the top of the fuel filter and the 4th injector to the tank.

I fitted clear hose a little while ago to check for some leaks.. and i'm sure i saw fuel going from the top of the fuel filter to the spill rail.

Backleak rail can connect anywhere on the low pressure side going back to the tank. Its not critical exactly where it is routed, peeps often make their own, I always keep nylon fuel pipe and a few fittings in case I want to make low pressure pipes.

its usually best to get your pump and injectors done at local injection specialist not from parts suppliers

I would agree hundred percent with that, and also think its worth being wary of real cheapies, I don't think it is possible to prpperly rebuild and test for £200.

of course you don't :doh: :lol:

I know that now!

Hopefully this will be the end of getting the engine back up and going!

it isnt , ive had a few to fit at one time and another all were crap

Big Mat · Apr 30, 2013

Craddocks are trying to screw me over getting the surcharge back on the pump due to the holes on the one i sent them being modified or something. Thankfully i've got another one i can send them. I want the £240 surcharge back!

I'll have to get on the phone to them about them paying for fixing their shoddy work, i dont think they are going to like it but its cost me a fair bit to get it sorted!

Friend bought a pump from an upcountry supplier, timed up ok but was leaking within a few weeks. After getting leak fixed it was another fortnight til it happened again. When he put it in for rebuild locally turned out all the sealing washers had been reused

been a while since i messed with 2 1/4 dervs, but isnt there a restrictor on the output side of the filter where the spill goes back to the tank? seem to remember i had an issue with derv circulating round the spill line instead of being drawn off by the pump.

yeah its what you explained to me with mine wich was me problem but it wasn't on the filter it was on the bottom.fuel intake on the fuel pump direct from the loft pump should ne an inbound one.way valve wich mine was open and flowing back to the lift pump

is it normal to have fuel constantly pumped back to the spill rail from the top of the filter?

yes.
thats why theres a restriction, to allow pressure for the injector pump to draw off what it needs.
fuel that isnt needed spills back to the tank.

Oldseadog · May 1, 2013

If the rail is connected to one of the inlets to the filter there should be no fuel flowing back towards the injectors as the bleed off is delivered back at a slightly higher pressure than that from the lift pump.

Here's a little pic, it currently is awful going up hills, but i assumed it was due to compression or timing.

red is the flow of fuel to the spill, it constantly flows to the spill.
green is back to the tank.. so it may be flowing that way to the tank.

(I promise not to totally hijack your thread mat

2.25 diesel just will not start.
