Need Info On Fuel System Components
Im trying to find a short in my electrical system. Everyday, I wake up to a dead battery, and on the road, it seems to cause a really bad sputter sometimes when I get on it.
I found that the short is somewhere in the fuel system, causing the Idle controller, O2 sensor, MAF sensor and a box with a bunch of vacuum lines running to it to stay hot after the key is removed. When I pull the fuse for the fuel system components, everything that was powered is turned off, and my battery is saved. Are there any other parts that are fuel/fuel-metering related that I should check? Possibly something sticking, like a relay I dont know about? I would really like to check parts first before I have to rip apart the harness to shoot wires. Any help is appreciated. A full electrical schematic is more appreciated!

I finally broke down and took the car to a dealer once the check engine light came on. Turns out all those parts were staying hot because my ignition relay got stuck, and melted. The relay wasnt in any of the fuse boxes. It was way back under the dash... something that doesnt get messed with too often I guess. The check engine light came on because the thermal sensor in the engine took a deuce and was causing the radiator fans to stay on, even when engine was freezing cold. About 100 bucks for parts and diagnostic work and the hooptie will be on the road again.
