2.25 Diesel - won't start

Newbie here i'm afraid!

Just bought a 1973 S3 88 2.25 diesel as a project (very cheap).

Thought i'd see if it would start, new battery and fresh diesel.

Got fuel through the pump using the primer, fuel into the filter o.k. and fuel into the distributor (if thats what it's called) looks o.k.

Nothing coming out of the fuel distributor so I removed it to check the little drive shaft hadn't snapped or the distributor hadn't seized, all good.

Any ideas where to go next?

Cheers,

Have you checked the injector pump and injectors?

Crack off the hard fuel pipes at the injector end, each in turn and see if you are getting fuel up there too.

I think that is what he means by the distributor

Thanks for the fast response guys

I undid one of the feed pipes from the injector pump (at the pump end) to the injector and there was nothing coming out of the injector pump when cranking the engine. I removed the injector pump to see if the little driveshaft at the bottom had broken (which it hadn't) and then checked it would spin by hand which it did.

I've heard that there is a fuel stop on the injector pump (controlled by something that looks like a sort of old choke cable by the ignition barrel). Is there anyway to check if this is faulty or seized closed / open so that no fuel can get in?

The pump has CAV written on it, does anyone have any info on it or is that too scary to mess with?

Cheers

Hiya
I would just try moving the lever and see if it moves, if it does then take off all four injector pipes and turn engine over and see if fuel comes out with cable pulled or not pulled. From what I remember, its been about 10years since i had a 2 1/4 diesel, the injector pump is not something you want to take apart. Assuming you get fuel coming from injector pump and can then time it. Either a pop rivet shaft or a drill bit slipped into the hole for injector pipe 1 is useful to get the timing right. Then the problems i always encountered were with the ballast resistor to the glow plugs and having enough power in the battery to turn it all over sufficiently.

have you opened the bleed valves on the pump to make sure you have no airlocks in the pump, there are two of them and both should have fuel coming through when using the primer
