Hi we are in the process of putting a 2002 engine into a 2000 TD5. Before I did it I asked around and some people said it wasn't possible because off different pressures but then a few people said it was if you swaped the injectors over. Which I have done.
The engine runs fine for about 10mins and then shuts off, had someone from Landrover come and test it and he said all the injectors and electrics were fine that the problem we had is mechanical. Possibly the fuel pressure switch, fuel pump is screaming (altough its new) but when he disconected the air filter and sprayed carb cleaner in the hose it ran for ages then seemed to run out of fuel, sprayed it again and it picked up. Runs better than it ever did, really responsive just cant get it to go for long enough!
If I make any progress on getting it sorted I'll let you know, would be interested to find out for sure myself. If you or anyone has any info on pressure swithches and the difference between the two types I'd be grateful if you could drop me a line. My philosophy of if they can put a man on the moon then I can put a newer engine into a TD5 is costing me a fortune!
