Broken crank

ok crank went on my freelander1 2003
Obtained another engine had it put in ,but won’t start,been told I have to change the injectors from my old engine to the new one to make it go,because the Ecu won’t recognise the injectors
Can’t I get it remapped or can I use the Ecu off the donor vehicle
Thanks frustrated

I'm assuming it's a TD4. That's the only FL1 engine that breakes cranks.

The injectors aren't coded to the EDC so should still work fine.
Check the rail sensor for corrosion. Otherwise it could have a duff O ring on the high pressure fuel pump regulator.

Been to two garages with it both telling me the injectors need coding and yes it’s td 4 engine

Td4 injectors do NOT need coding. I’ve swapped them around before and had no problems. Find a better garage.

Alternativly a mate of mine has just put his td4 up for sale and i know its a good un

The motor spins over but won’t start unless easystart is sprayed into air intake .dave

Maybe it’s a fuel pump,perhaps

No coding of injectors is needed to run the engine.
If it's starting on easy start then the injectors are fine.
However that is a symptom of a split regulator O ring.

Can you tell me where the split o ring would be please dave

Also, could be one or more injectors leaking back during cranking, dropping rail pressure.

As well as reg O-ring I would suggest a leakback test.

If the old engine was running and you still have it. Then pinch the high pressure regulator off the fuel pump.

Don’t have the old engine unfortunately

That's a shame. There are a few parts that could have been salvaged and kept as spares. The HP pump being one such item.

Ok
Eventually replaced two o rings after the engine swap and the landy is back in the land of the living
No need to upgrade Ecu etc
Thanks foe all the help
Dave
