This one was wierd. My Rover wouldn't stay running after sitting cold for about a week. When I engaged the ignition (just before starting) the fuel pump would come on (that faint whine noise from the tank), then go off, then come on, then go off in uneven intervals. On each successive crank, the engine would quit, I suppose because the fuel pump had quit. I immediately began to think of a short.
The first place I looked was the fuse box. Sure enough, the fuse for the fuel pump was bad. So I replaced it and she started up fine. So I felt like that fixed it. After running for about 30 minutes and a quick drive around the block, I pulled back in to my garage.
When I turned off the ignition, the engine stayed running! Pulled the key out and everything. I had to stall it out by popping the clutch (dangerous in the garage!).
What I am wondering is, are these 2 things somehow related? Curious, mostly.
