Hello, Has anyone got a 14 CUX ECU for Discovery 1, 1997 3.9 V8 with cats. If you know anyone has one please get in touch. Many thanks Ian

Well I have made progress and its by accident really. I had a feeling the ECU was at fault, took it out and contacts looked OK, put it back in and moved it and the wiring around and the clicking slowed down, pushed on the ECU connector and its stopped the clicking at the relay and the fuel pump...

OK cheers, I will do some electrical measurements at the fuel pump relay later this evening Ian

OK found the purge valve and on the vehicle, no bypass up to the valve, must be going somewhere else. Maybe someone bypassed the valve, can this be done?

cannot find a purge valve in the manual, I will do 12v tests to the relay tomorrow

OK appreciate the input, I do have the manual so not working blind as such, OK i have an anomaly which is good, there is a bypass wire going to the purge valve, I have tried wiring the old white and purple but nothing happening - the alarm just comes in eventually, reconnect the bypass and...

Straight forward replacement relay, used the correct numbers. Yes I agree with you about the fuel regulator - it should not 'click' I think it is the fuel pump pulsing but the relay is definitely clicking. I just cannot figure out why its working ok after a short time running and running ok...

Hi Discool, Update, changed the fuel pump relay and its doing the same thing/symptoms. Basically the pump is running continuously, EML flashing, fuel pump relay clicking and fuel regulator clicking away before I start it up from cold. When I start it up and it does start no bother it is as rough...

Just went to lock up, thought I would try it again, looked for the 'clicking noise' it is coming from the fuel pump relay Ian

OK tried the V8 again this evening, again rough as when first starting and EML flashing, read a post on here about earthing out the Fuel pump relay, no clicking noise now. Disconnected the fly lead and it started on bother with a very steady tick over, shut it off and I could hear the fuel pump...

Its not shutting off, i am more familiar with motorcycles and they prime up and **** off until needed, when i turn the key pump continues to run

Thanks for reply Discool, OK should the fuel pump shut off when primed or does it continue to pump? Its a difficult one to try and write down.

Hi All, It's been a while as I have not done much work starting up the V8. Work done in last 6 months (could be more!), taken off old downpipes with cats to replace the lambda sensors. Snapped a stud in the exhaust manifold, took that off - bit nervous would snap studs but they came out great...

Its been a while since I have posted but not much happened with V8 I had problems getting the old Lambda sensor out of the exhaust so decided to take Y piece down pipe off, well bit of a chew on and it came off, 1 snapped stud in manifold, tried getting it out - no luck, manifold is off to...

Thank you, Ian

Hi All, Drop links for anti roll bar D1, are they the same front and rear? Its been a while since I have posted but not much happened with V8 I had problems getting the old Lambda sensor out of the exhaust so decided to take Y piece down pipe off, well bit of a chew on and it came off, 1...

The V8 runs a lot better on LPG but still flashes up EML when running low revs Ian

Hello All the guru's, My very late model D1 V8 is OK when I start it up but when I have driven it for around 4-5 miles it starts to run rough and smells rich from exhaust. I have had my ECU mate on and there is a huge imbalance readings on the Lambda sensors, bank 2 reading is very high and...
