Hi All

I am the owner of a Landrover Defender TD5 90 2000 which has an issue that 4 mechanics have been unable to resolve. Can anyone here solve the mystery?
The fun began when she failed her MOT due to a few rust issues. Her fuel tank had to be removed to do the job. She drove home fine but refused to fire up again as if she was not getting enough fuel. To each garage I have asked the same question: 'could there be a connection between returning the fuel tank and the engine cutting out?'

Garage 1:
The ECU loom was contaminated with oil - cleaned, reconnected, power supplies checked and OK. No output detected to injectors. ECU oil contamination so sent for refurbishment. No fault found so refitted.
Insufficient pressure to pump enough fuel to injectors - New pump, filter, injector seals and injector wiring harness fitted. - Pressure fine - still non start.
Specialist brought in - poor connections in wiring loom to fuel system found and cleaned, wiring to glow plug and poor earths repaired.
Wiring issues had caused loss of synchronisation and communication between alarm and engine ECU's - system reset and synchronised - engine now starting.
Faulty battery replaced and engine oil and filter changed as fuel contamination present due to injector seals/cranking.

2 weeks later, malfunction warning light comes on and engine cuts out whilst driving

Garage 2
After a week's rest in their forecourt, engine starts fine, they move it around a few times and call me to collect.

5 mins after collection, malfunction light and engine cuts out whilst driving.

Garage 3 - Specialist Landrover Garage
Found mass airflow sensor not operating correctly and engine relay corroded internally - both replaced

1 week later, malfunction light and engine cuts out and restarts whilst driving.

Garage 4
Above work checked and vehicle road tested - did not cut out

30mins of driving later, malfunction light and engine cuts out and restarts whilst driving. Drove 30mph home which reduced cutting out. Garage 4 has agreed to remove fuel tank and answer my query.

Any suggestions anyone?

Thanks
 
The intank pump has a couple of gauzes one finer than the other and they can and do block up.

Also if the top of the pump is the same pipework set up as the disco version its possible to get the pipes in the wrong holes.
