At a Complete loss

[Inchdagrinch]

Hi all.
My 1999 disco 2 will not start she cranks and cranks but wont go. I changed the glow plugs. Cleaned the engine ecu tested the ohms on the crank shaft sensor and seems fine.

Got her plugged in and showing no faults.
Really don't know what to do. And I pressed the inertia switch.

I'm at a real loss hopeful regards

First Welcome to the forum....

Second I really hope someone from across the pond who knows Diesels will chime in and help. I haven't even seen a Disco diesel.

Thank you for the warm welcome. And yes let's hope someone has an idea.

Air?
Fuel?
Fuel pump (functioning &shutoff not stuck)
Timing last checked?
Timing Belt?

You don't provide any mileage or other info on what led up to this.

How many miles?

Was this sudden or has it been getting harder to start over time?

Any recent repairs?

As above, Diesels are pretty simple machines. Compression, fuel, timing. My Volvo Diesel died a slow death until it just didn't have enough compression to start.

Hi sorry 180k. No recent work done to it, was driving and just lost power and wouldn't start. Now I have changed crank sensor fuel pump fuel filter glow plugs it starts 1 in 10 but wont rev and then cuts out.

I don't know what engine is in a Diesel Discovery but my VW Diesel powered Volvo that was extremely well maintained from new just quit at 180,183 miles. Not enough compression to go boom.

If you can verify that you are getting fuel to the injectors then next is the compression test. Diesel compression test kits are a little rare and a little expensive but you are going to probably need to have that done.
