TD4 Starting Issue

Hello,

I am currently attempting to repair a 2003 Freelander TD4 for a friend.
My friend finished work, jumped in the car and attempted to start, it cranked and didn't fire.
This was consistent, there were no missfires or "close starts" - it just plain refused.

The AA was called out and the diagnostic computer was plugged in - this showed the cam or crank sensor (no printout given).
The Freelander was started with a quick blast of easy-start and ran - idled fine but lacking power - Engine Management light was illuminated until it was dropped off with me.

So far, this forum has been an invaluable resource, I have read a few no start threads and found a lot of information.
I started diagnosing by going to the fuel-pump inside the wheel-arch first. This sounded healthy and was flowing diesel to the fuel lines in the engine bay.

I have purchased used cam and crank sensors (awaiting delivery).

I also carried out an injector leak-back test whilst I was cranking the engine - injector 3 seemed to flow excessive diesel from the top. I have purchased a used injector with the same part number (044511C 049) - my question is, do the injectors need to be "coded" to the ECU, or will it be happy just being swapped over?

Many thanks.

the injectors do not need coding on the TD4, so should be a straight forward swap

That's great - thanks.
Will let you know how things go.

what mileage has it done have the fuel filters been changed .

The used sensors and injector turned up yesterday.

- Swapped over the sensors, still nothing.

At this point I noticed the EML on the dash illuminate, extinguish then illuminate again shortly after when the key was in position II.
This signaled to me that the engine had done its self checks before start, and something had failed.
This then made me think along the lines of fuel pressure.
Obviously the car checks pressure along the rail before start, if its not happy then it wont tell the injectors to fire any fuel.

Swapped over the injector which appeared to be leaking-back the most (was thankfully loose - I have heard a few horror stories about removing injectors) and it fired straight into life again.

Back on the road again, spent £30 on sensors, £50 on an injector & £65 for a fuel pump and filter for good measure.
Dread to think what a garage would have charged - im guessing they would have bought new sensors and a new/recon injector.

The existing pump and filter had been replaced in 2011 - around 20,000 miles ago - car is currently on 98k.

Thanks again for the advice.
