Hello,
I finally got my Defender back after the garage struggled to find my intermittent problem. It went in because I kept breaking down; the fuel pump starts making a noise, then it goes lumpy for a few seconds, then all power is lost. The lights come on, and it's over. It's a pain to restart, which involves going through the priming cycle for ages until the pump gets quiet.
They guy at the garage said he's done everything he can think of. Unfortunately I broke down again on the way home
The noise is definitely air in the system. I've heard it before when the injector seals went a few years ago.
I don't think it's any of the following (they've all been changed with genuine in the last few weeks)
- Fuel regulator
- Fuel pump
- Injector seals
- Air mesh thing on the fuel filter housing port.
- Fuel filter
Within the last couple of years I've also changed the injector harness and fuel filter housing. I can't find any fuel leaks.
When it's sitting idling, it runs fine. When I was driving 'harder' - ie demanding a decent amount of power (up a slight hill, accelerating, 50mph) I could hear a hissing noise from somewhere - and I broke down soon afterwards. When I thrashed it to get home after getting it going again, it broke down after 500 yards. Then I tried minimal revs, 3rd gear, and it got me the 2 miles home in one go. The hissing could be from something else I guess, but it does get louder with the amount of power. I left it sat idling on the driveway for an hour and it was fine.
Anyhow, what's left for me to try?! A faulty injector maybe?
Nanocom doesn't show any related errors. The cylinder balancing screen shows variations between 2 and about -4. Not sure if that's good or not?
Help! Please
