Engine not starting or cutting out

Hi all hope this is the right place to post this.
My LR Defender TD5 2001 would not start the other day but it was not starter motor issue. I left it 20 minutes and it started first time but 100 yards down the road the engine cut out.

After that I could not start it.

Could this be a fuel issue as somebody suggested turning the ignition on and pumping the accelerator 5 times and then starting the engine as it engages the fuel pump?

Also anybodhy know of a website where I could get a valaution for selling it?
Cheers

Check relays are tight under seat i think on them

For valuations, take a look a the likes of autotrader, eBay and the LRO classifieds. It’s all dependent on condition as opposed to age. Putting a value on a defender isn’t as easy as doing so for a boring car of the same age.

Could be a failing ECU. Do you have access to a suitable diagnostic computer?
