2.25 diesel just will not start.

Big Mat · May 1, 2013

Fuel system is all back together.

Unfortunally i have a feeling that the very dodgey join in the fuel pipe at the tank end is letting air in, so i'm going to have to replace that before i go any further.

Turning it over sounded promising though!

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 )

Its a while since Ive had a 2 1/4 diesel but that isn't how I remember the low pressure system. As previous posts there doesn't seem to be a restrictor screwed into filter head! Also some of the pipework doesn't look like fuel pipe at all. There might be flow diagrams in a manual if you have one.

clear stuff is me mucking about using clear pipe to see the flow

sounding good! hope it fixes it

It is the thick black rubber pipe that was worrying me! I think all the low pressure pipes are nylon as standard, not sure exactly wot yer got!

Looks like high pressure fuel pipe..this thing has err been played with in the past

Best go back to original set up if you can. Like I say its a while since I had a 2 1/4. Heres a pic of my whats on my 2.5, not a very close up pic Im afraid, but I aint going out in the dark to take one!

OK, if I read this correctly, you have the blue which feeds the Injector pump, purple is the feed to filter from the fuel pump and green goes back to the tank.

Why is the red there as all of the flow off can either go directly back to the tank or into an inlet on the filter?

Might I suggest that you explore the possibility of plugging off the unnecessary red pipework, and see if that makes a difference?

Yeah ill order some bits, the whole bay is a mess.

Maybe to stop a pressure build up in the filter?

Just managed to find my 2a book and it looks like its hooked up ok for the later fuel system (the end pipe and 4th injector pipe are the other way around - but it doesn't look like it matters) so good times. Thanks all.

All assembled with a new fuel pipe.

When turning over it sounds like the engine is running, all be it not quite at full whack so i presume just air in the system or tweak injector pump timing to get it going.

There will be a lot of air if you have reassembled the system. Bleed the filter thoroughly at the topmost fitting. Then the two screws on the pump, pump lots of diesel through with the lift pump, I put a bucket under, it ruins tarmac

When youre sure pump full of fuel get someone to turn it over while you slacken ann injector pipe, when that's bled do another it should start, helps if its warmish when you do it.

Big Mat · May 4, 2013

Well it runs, sort of.

Bled her all up and got it going, cloud of smoke and no power when i tried to move it. Left it running for a while then cracked injector pipes again to get rid of any remaining air.

Then after running for a few minutes, it just died and now wont go again?

Plenty of fuel there but it wont run

Yet know mine has just done the same thing and im sure this time its the rings gone in the pistons so im either looking for another engine or sourcing a new set of rings

Big Mat · May 4, 2013

When i just tried turning it over, it sounds like its going to shake the car apart!

did you say you have redone the timing chain?

if it's now starting to run for a bit (although rough), i'd start playing with the pump position. What colour smoke is coming out the back?

don't give up!

Big Mat · May 4, 2013

I have not done the timing chain.

Smoke was white, maybe getting a little toward grey.

Battery is charging at the moment, was thinking of advancing the pump slightley and giving it a go.

yep, that adds up. looking forward to you saying it is running, by the end of the day

why do you think rings are gone thought youd just rebuilt it ,did you gap rings in bore ?

Big Mat · May 4, 2013

Right all work has now stopped on this engine.

I tried advancing the pump with no luck. Engine just didnt seem right so i took of the rocker cover to check that the rocker i had replaced was still fine.

Then i found that another rocker had snapped in half!

When i first started having problems i discovered that rocker number 3 had snapped in half, i replaced this along with pump etc etc.

Now number 7 has snapped in half, i suspect something is seriously wrong inside the engine!
