More...

Drove back from Tahoe to the Bay Area yesterday. About 15 minutes into the drive, I got the blinking dash lights and the disco locked in 4th gear. Shut it down, restart and reset the lights, and keep driving. I stopped at the LR dealership in Sacramento to pick up a new inertia switch - kept it running at the dealership. She drove fine the entire time, about 5 hrs.

I got home and promptly replaced the inertia switch. She started right up. About an hour later, she would only crank - not start. I unplugged the switch and tried the paper clip trick again - nothing. I plugged the new switch back in and gave up for the night.

This morning, she fired right up. It almost seems like some sort of time based inmobilization functionality is the culprit.

I drove around for about 1/2 an hour and got the blinking dash lights again. Shutdown, restart and clear. I'll restart every 5 to 10 minutes to see how long it takes to not start again.

Thoughts?

So I bought this 01 disco 2 that had a hard start. Checked fuel rail pressure after vehicle would no longer start, it would take a long time to build pressure in the system and it would barely hit 50 psi "bosch engine". So after reading about the system only having a filter inside the tank attached to fuel pump assembly I decided to throw a new bosch pump at it....installed and tried to start again nope not happening. Me being not really familiar with the rovers I decided to install a new fuel pump relay and for shits and giggles a new cps since it barely have 90k miles why not right? nope nothing. Spark looks real good in case someone asks later. Now after scavenging the forums I decided to check the ground status at the pump, now when my wife tries to start the car it goes from 0.00 ohms all the way up to 5 ohms. Now me personally it may seem like I have a ground issue but I have yet to drop the tank and start inspecting the pump harness. Now I have read that people have issues with wire bundles wearing through under the engine fuse panel on the passenger side. Should I start at the fuel pump side of the harness or engine side of the fuse panel? or go a totally different direction?

I'm guessing you did but I don't see you actually saying it here - did you reset your Inertia Switch? It's located under the hood, against the FW on the Passenger Side. You just press down on the top of it and you should hear/feel a click

Sorry if you did this already but again, not spelled out above - just asking.

I did yes, I feel it click but doesn't stay down. I'm assuming correct operation due to no flashing lights and I also tried jumping the wires to test if the switch was bad.

I'm leaning more towards the wiring harness at the pump. Here's some pics you can see the condition of the area if helps provoke some thoughts lol.

Measure voltage in the plug across the black and white/purple wire when ignition is turned on, if you get 12V make somehow ti measure with the pump conncted too and if it drops much we'll speak again... do you have RAVE?

So I tested said wires and this is my result. I have downloaded the manuals from someones post and not sure what rave is? I know it has something to do with the manuals for the rover. Is is a sub based manual service?

Also to note that the previous owner replaced the interior fuse box panel.

The interior fusebox should not affet the pump... it seems there's no feed to it... remove relay R1 and make bridge with a paperclip across the perpendicular cavities then measure voltage in the plug again, also make sure that fuse F10 is not blown, if the fuse is OK measure voltage between the paperclip and body(earth), if you have voltage on it and no voltage at the pump see between the white/purple wire and body to see what's missing there the live or the earth.

for future troubleshooting download this: https://www.sugarsync.com/pf/D8700125_05791262_29834# go to ''connector views" see C0376/0390 pin 2 and measure there against earth to see if you get 12V

So apparently I was testing the connector wrong. I had my wife try to start the car as I tested and I got 11.80 and stabilized at 10.80 while trying to start. Not sure if that's within acceptable limits or not. I will check relay connections tonight before I pass out for bed! Thanks for the replies btw. It really helps bouncing ideas and receiving feedback as I troubleshoot this.
