300Tdi Defender cutting out

Dec 05, 2005 9 Replies

Had a bit of a weird one on my way home last night. Driving along at around 50 in 4th and the motor died - just as if it had been switched off. Restarted OK after switching off and back on. Happened a total of 4 times in 30mins, 3 times when stopping at junctions.



I'm thinking ignition switch starting to fail, any other suggestions?

Does the 300tdi have an electric fuel cut off solenoid like the 2.5d?

I'd suspect dodgy wiring somewhere. Either the whole ignition or just the feed to the cut off.

Feed to solenoid valve on fuel pump. My immobiliser developed a fault and I had similar symptoms. In the end I fitted a by pass wire.

That sounds like you might be right - pretty much what happened to my 110 (the only time it's ever let me down, though I did manage to get back to base by holding the the key in just the right position - don't try that at home kids!).

It could also be a loose wire to the fuel cut-off switch on the injector pump.

And....

Same thing on mine - the connection of the cable to the spade connector had failed at the injector pump. New spade connector, all well agan. Interestingly, I had previously had a problem with the rev counter dying, which again turned out to be cured with new spade connector. In 1997, I don't think they were doing these joins well, and they seem prone to corrosion.

When my engine cut out the first time, it was during overtaking! Almost a brown trouser moment! Graham Carter

Thanks for all the suggestions - I'll have a proper look at the wiring in the morning when it's light (and with any luck not chucking it down).

yes.

so would I. or maybe an iffy cut-off sdolenoid on the pump.

Had a better look & fiddle this morning - it looks like the ignition switch, cut out as soon as I tried to steer, completely off with no dash lights, careful wiggling of the key brought it back to life.

Now just need to get a replacement & fit ASAP, I was supposed to be with a customer 150 miles away today & tomorrow.
