So my Explorer all the sudden quit starting. I had the car in the shop about a year ago for a car alarm install. This place really didnt do a very good job at installing the alarm. By the time I figured this out they were out of business. Anyway there is a Starter kill wire not going to anything. COuld this be why the car doesn't start? Where in the heck does it go?


I think I may just trace out each wire and uninstall the alarm.

If you can tell me a brand and model number I might be able to help you.

If the wire in question is the orange wire coming from the white 10 pin harness then that is the starter kill wire. However that not being hooked up should not prevent the truck from starting. That wire outputs a ground when the system is armed. If the starter kill was installed thats different. If thats the case there should be a relay with a diode across the coil terminals somewhere that the orange wire connects to. The only way to tell for sure is to check the starter wire in the steering column. if the violet wire is spliced in and the starter wire is not cut, then the relay wasn't used. If the starter wire is cut and the violet wire is spliced to one side then the other goes to the starter kill relay. Hope that helps, let me know if you have any more questions.

Oh yeah, this might help. The starter wire is red with a light blue stripe. It's a heavy gauge wire in the main ignition harness in the steering column. I guess I should have asked this from the start(start, I kill me), but does the starter crank? If it does than the starter kill isn't your problem. If it doesn't the you're on the right path. If the starter cranks but doesn't start, it could be the bypass module. There is a module that bypasses the PATS system and tricks the truck into thinking that there is a key in the ignition.

Thanks for your help! Im pushing the truck out in the drive way so I can actually see to work on it.

Yeah the start the engine turns over. I thiught it might have been a fuel pump cut off switch?

I really wish I could drive this truck through the showroom window of that place. Its a nightmare under the dash.

*Fixed. I traced out all the wires. It ended up being a short in the raditor coolant sensor. Replaced and truck starts fine now!
