95 Disco 1 3.9, runs and drives great for weeks at a time. Then all the sudden the fuel pump won't kick on when I turn the key, no start. Then sits a few days and it is fine again for a while. Is there a relay or something that is having a condition to cause this issue? Alarm problem maybe? Any help would be awesome, I have been chasing this gremlin for almost 6 months.
Thanks all for any input!

 

I believe there is as relay, not sure what the alarm kills, there is the rollover button on firewall

Have you checked for codes?

Checked the plug at the pump/ sender?

 

sounds like a burned wire connection. Mine was at the plug for the inertia switch (under the hood)

 

First step is to download the Rave shop manuals and look at the fuel pump circuit in the ETM. Best way I've found is to start at the offending unit and work your way back.
