Definately sounds like fuel pump though, The last one I cut open, the brush holders on the motor had melted and dropped off, they were PLASTIC!!!!

It had done about 130,000km.

When you pulled the pump apart Justin, was the brass filter at the bottom of the pump blocked with a black goo?

On the pump I pulled apart recently (after 130,000kms) this brass filter was almost completely blocked. The car was still running but not very well. Interestingly, the plastic filter on the outside of the housing was quite clear - indicating that possibly there was some sort of reaction between the brass(?) filter and the fuel.

While on the subject of Td5 fuel pumps, does anyone know if there is any difference, apart from price and colour, between the Disco and Defender pumps?

Thanks for all the help so far, pending the error readout next week it looks like I'm going to be up for new fuel pump.
Does anyone have the details on the Ford v8 replacement fuel pump mods to suit Td5 Disco ?

Thanks in advance

in the trailer I have an allegedly dead td5 fuel pumo.

watch this space......

After finding the fuel pump was ok, (before being replaced), in one last desperate attempt to find the problem we installed another ECU. It ran perfectly for nearly 3 weeks in all types of driving, hot or cold days etc. The thing I missed most was that my original ECU was Triumph Rover Spares chipped. and the power and driveability was seriously undermined. I rang TRS and spoke to Phil, after telling him the problem with the ECU he asked for it to be sent to him for inspection . He rang early the next day to tell me that they had checked the chip etc and found no problem, but when they tapped the case the engine would falter or stop if hit a little harder. It turned out that the bottom of the circuit board was arcing out against the case where it was slightly bowed (hence long steep hills etc and hot days didn't help).He said he had seen it a few times before , but mainly when a bigger battery had been installed. Now the car drives better than ever, as the chip and everything else is as speced. From the time I sent my ECU to TRS and it was returned was under 48hrs, great service and product backup. I was just surprised nothing showed up on the fault codes, as this drama could have been cleared up months ago !!!

I think that's a very good result, including not needlessly buying another pump. Presumably the ecu was temporarily dying with the short circuit and therefore was unable to record any fault codes.

Great result!! Hopefully not too much expense incurred to find that out? It's a great feeling of relief when someone finally nails the the problem.

Thanks Graeme and Phil;
yes to finally nail the problem was a great feeling, I will now always carry a spare ECU when I travel.
Love Diesels ; Hate Electronics !!!
