Mccormick b250 won't start

hi i have a mccormick international b250 with bd144 Perkins Diesel engine
that I've recently purchased

All was fine it needed 15secs of glow plug and it would fire after a few turns but after parking it up one night the next day it wouldn't fire

I removed the pencil type glowplug s and replaced with genuine Bosch loop type but still no good, so I pulled the injectors and found dirt/ rust in one so they were sent of and rebuilt but still won't start
I then checked the fuel filtre and there wasn't any! So a new one installed

I think with no fuel filtre and what I found inside injector maybe the cav inline pump is low on pressure but my dad says compression
I got it running with easy start and sounds sweet when running

I replaced starter and the battery with 1000cca tonight to make sure it's spinning fast enough but still won't run
It puffs out white smoke and with throttle lever fully open it try's to fire but just doesn't run
The glow plug indicator glows bright red near white within 3-5 seconds

Just not sure what to try next without wasting more money?

On my B275 there is an excess fuel button on the fuel pump, it is situated where the crank that operates the stop control enters the pump. Just put the stop control in run positon then pull the crank out and then heat the engine until the pepper pot glows on the dash board then engage the starter lever.

Mine doesn't have that

4 cylinder diesel? It wont be a Perkins at all. The only Perkins 144 is The P3/144 3 cylinder engine and l very much doubt that someone has took The IH diesel engine out and replaced with a Perkins P3, although l have seen that done with older IH W4 tractors, where they have taken the old spark -ignition engine out and replaced it with The Perkins, like they did with a lot of the Petrol-Paraffin Grey Fergies.

Mine has the XS fuel on the stop lever too. i think some came with inline pumps (like mine) and some later ones had rotaries.

Not sure why I put Perkins down but it is bd144

So is it the stop lever you pull or something next to it

Yes pull the complete lever out away from the pump towards you.

Make sure the glow plugs are working and getting hot, ive had a problem with this on the Bradford engine that is usually in these where they earthed out some how so the resistance in the plugs caused the current to bypass and go to earth. If the glow plugs are working properly then you don't need excess fuel as its a indirect injection engine where the atomised fuel is sprayed directly on to the red/white hot element in a pre-combustion chamber. If its suddenly become difficult to start it is unlikely to be low compression imho. Not having a fuel filter in is not great really. you should have loads of fuel at the injectors with the injector lines cracked off whilst cranking if the glowplugs are working then I would suspect a fuel problem of some kind.

Indirect injection are lovely diesel engines, when you get them started ............
Add to that age and you have an engine that needs everything just right for it to start.

A but if an update,
Tested continuity and found number 3 plug earthing out but only when in the head on its owns out of the head it was fine so I scraped the carbon out the plug hole and tried again and now it's fine put them all back together and now it seems to be working

As soon as I tried to run it it fired straight up but was missing and before I could grab a spanner it cut out

Cranked it over with the pipes cracked open and I get a dribble/ light spray

After tigening I cranked it over and it fired but then died cracked number 4 and air seaped out but not on the other 3
number 4 is the worse for getting anything when bleeding just a little dribble

Couldn't find a gauze filtre in pump

And I thought I would see if the air filtre was in good shape looks like it's never been changed and there was water sitting in the bottom of the bowl
When I got the tractor the intake pipe was off slightly so some how must of got in

Think it fuel problem now but not sure where to start!
What would make or be the problem when air come out number 4 and not the others after I've tried to run it and stoped cranking then cracked the pipe after it's stopped?

Found it thanks pulled it out and when it fired but then cut out in poped back in

Mursal · Nov 18, 2016

Have you plenty of diesel going to the injector pump?
Are you on a gravity feed or a lift pump?
Any air in the pump will give you the above problems .........

Bur finding the dud heater plug was a good find, your nearly there.
Take the inlet pipe off and let it have all the air it wants, don't stress about the filter at the minute .....

Mursal · Nov 18, 2016

This your pump, Billy?

John 1594 · Nov 18, 2016

Always reckoned IH named that range of engines "BD" as they were Bloody Difficult to start!!!

Gravity pump with hand primer
Bleed fuel at vent plug on pump was coming out fine but when cranking it over and crack injector pipes there's not much coming out

I think the plugs can earth out when the element touches some part of the combustion chamber when installed. Just make sure you've got loads of fuel to the inlet of FI pump as mursal says. Its a possibility if its not had a fuel filter that theres some gunk stuck in a union or filter in the fuel lines. It should have a lift pump I would think as it has an inline pump where the pumping elements need positive pressure whilst charging, so there might be a filter on the suction side of the lift pump. The engine I worked on years ago had no lift pump and a CAV DPA rotary pump...

I think that might be a plunger type lift pump working off the pump cam, (as opposed to a diaphragm type) ??? I'm pretty sure it will have a lift pump

Red Fred · Nov 18, 2016

On mine, the lift pump is where the t-shaped handle is in the photo (although mine has a question-mark shaped handle which you unscrew, then pump up and down to prime. )

Took all banjos of that lead to hand primer as in my photo above and there's no filtre just two springs and little stop valves
