Greetings,
A couple weeks ago, I drove my car someplace, parked it, and when I tried to start it again, it wouldn't start. I checked to make sure it was getting spark, and everything was fine, so it seemed to me a fuel problem. I spent the next day troubleshooting, and the best I could come up with was that I got no voltage on the fuel pump fuse (12v everywhere else, 0v on fuel pump) in the on position. I unplugged the fuel line and turned the engine over, and no fuel came out, which I believe verified the fuel theory. I was going to have the fuel pump replaced, but had the shop diagnose it first. (I have no garage and broke bolts on the fuel pump mounting, otherwise I would've replaced it myself)
I had it towed to the dealership, and they said it started right up and that I had probably flooded it. I drove it for a week or two, but it did the same thing again two nights ago on my way to visit family. This time the tow truck driver verified that the fuel pump is not buzzing when I turn the key on.
I have checked the wiring diagram in my Haines Manual, and is seems that both the fuel pump and the coil are on the same fuse, so having 0v should keep me from getting spark. I will check again once the weather breaks, but my initial diagnosis seemed that there was a problem somewhere between the battery (probably ignition) and the fuse-box that was intermittently cutting out. It doesn't happen when it's running, only when I stop and start, which seems to imply the ignition switch itself. This would not explain the spark in the coil though.
I am unable to find a wiring diagram from the ignition to the fuse box, so I can' tell if maybe there is one wire or lead from the switch that feeds the fuel pump fuse, or if the ignition feeds a rail that all the fuses are supplied to.
I would appreciate any insight that any you might have. I would like to get at least another year out of this car until I can get something newer and give her a bit of a break.
Specs: 92 Loyale - 1.8L, 5 spd, Fuel injected.
PS While she was running, she had no problems with the snow here in Seattle. Yay Subarus!
