1999 TD5 Defender will not start.
It stalled while driving, restarted to get it home. After that it would not start again.
Replaced fuel filter and later the fuel pump. No result. Ran the fuel system purge repeatedly. Checked ECU connector and found oil. Cleaned; still nothing Checked crankcase oil for signs of Diesel. Diesel found in engine oil. Changed injector seals, copper washers and injector loom. Still will not start and nothing coming out the tail pipe when cranking. Checked CPS. Pretty dirty so I cleaned and tested with ohm meter. Reads correct (1.24 kohms) tested connectivity from CPS to ECU, also tested good.
Held Rag soaked with petrol up to breather intake while cranking the engine and the engine tries to fire with smoke coming out the tail pipe. Take rag away and nothing, no smoke.
It acts like it is getting no fuel to the injectors. Disconnected fuel line going to the fuel regulator and put the end of the line into a can. Turned on the fuel pump for a second and the can was half full of fuel. Did the same to the line coming out of the regulator with the same result.
The ECU seems to be working properly; The correct lights come on when cranking; glow plug, engine, battery and all go out if you leave it on. Also, Can set alarm and deactivate with no issues
Not sure what else to look at, any help would be appreciated.

Unfortunately no... I have a fuel pressure tester but not one that I can connect to to this setup.

There is a fitting coming out of the fuel regulator going to the cooler. I may be able to connect my tester there. Should it be 4 bars coming out of the regulator?

Great! I will give that I try.

Thanks!

How can you test the voltage coming from the CKP? Do you not need an oscilloscope to see the pulses? Or is it a constant DC level?

So I just tested that with a volt meter and it is putting out .583 volts AC with slight variation.

I just had the strangest thing happen. The was testing the output of the CKP while cranking and the engine came to life. I revved it up and it ran for a few seconds then stalled. I started it right up again and it ran for about a min then stalled. Now I can not get it to start again.

Checked from the CKP connector to the ECU connector and both wires tested good. Cleaned both connectors again and plugged it back in but still not starting. I wish i knew what made it start earlier today but I cant seem to replicate. I was testing the CKP while cranking the engine, but I was also changing the settings on the muli meter when it fired up.

The amber engine light comes on for about 3 seconds when you turn the key on. It also flashes when running the fuel air purge cycle.
