I have a 1998 4.6L F150. I bought this truck used, and haven't had any issues except a fuel pump replacement early this summer. My problem is, when the wipers are turned on, the engine stops. BEFORE YOU GUYS SCREAM AT ME, yes I read a similar thread but, this issue is a little different. First of all, my truck won't start at all now. The issue with the wipers started 3 days ago. I figured as long as I didn't use them, the truck would start and run normally until I got it checked out, but I got home 2 days ago, and just to see if the problem was a fluke, I turned on the wipers and the engine shut off...permanently. Now, it won't start at all. The previous owner removed and aftermarket alarm, but again I've not had any problems with the electrical/ignition system since I bought the truck. I'm stranded in my driveway, I live in the sticks and any help would be appreciated.

 

Does it crank, or you have no power at all?

 

You've described two problems, that might not be associated. The permanent problem would be a power supply problem. Probably a blown fuse.

SHOUTING at people to not SCREAM at you doesn't really make anyone want to get involved. Kind of pointless. I've only been on this forum for s short while but I don't see any screamers.

You need to do a better job of describing the problem. "Won't start" doesn't tell much. Can't even tell if the engine turns over when you turn the key. Does it spin, does it click, does the rest of the electrical work? Details.

 

The switches are close physically so I would start there, after checking fuses, but something would have made it blow if so. Pull the ignition switch out and the wiper switch and check over all wiring. They aren't difficult when you know how. Look for instructions because it's a little tricky.
