Default Intermittent Starting Problem

I have a strange problem with my 1997 Disco 1. I purchased it a few months ago and did the recommended 60k service. The problem is that it will start most afternoons but will not start most mornings. There is no power at the fuel pump when it does not want to start. There is a new fuel relay and the fuel pump is new. Thanks for any help!

Did you replace the fuel filter? Have you verified fuel pressure in the mornings before you start it?

The fuel filter is new. When it starts, the fuel pressure runs at 30psi. Overnight it will drop but there is still some pressure. If the fuel pump comes on, the car will start an run fine. I had figured a bad relay so I replaced it. Same problem.

I have heard of this problem more than once but everybody who had a problem never posted the repair.
Sorry that I cant help other than it has to either be a electical issue or a alarm problem.

Make darn sure it is in park. Next time it won't start, apply the brake, with the key on and shift to neutral and park a couple of times. Then try to start.

Interesting.... If the car is not in "park" would the engine turn over at all?

What in the alarm system could impact the fuel delivery? When I bought the car, I recieved a key but no remote. Is there some "wierdness" in the alarm system?


Thanks again.....

Is there "weirdness" to a Rover? hahahaha...YES!!

The alram kills the power to fuel pump.
Not having a remote wont matter.
If it is not all the way in park it should not crank at all, but shill try what OKDGuy said as these trucks are very...weird.

EDIT: Later tonight I will post some alarm "fix" links.

Thanks Spike555 and everybody. I will watch for the links.

In the mean time, I will review the Rave manual and see what I can find on alarm relays.

As strange as it sounds, I enjoy a little detective work.

If I find anything, I will let you know.

I believe the inertia switch under the hood also kills the fuel pump

luck,greg
