Hi, my 1999 Ford F150 engine is turning over on it's own, it's not actually starting, just turning over continuously. Once turning over, it occassionally stops, but then will try again after a minute or so. I have seen a few other people post this issue, but there are no responses with what the fix was. fyi, there is no remote starter on this truck. If you have solved this problem in the past, please advise. Currently, I am planning on changing the ignition switch and/or starter, but dont' want to have to spend a fortune changing everything, so any advise on previous experience would be greatly appreciated. Currently it sits with the battery disconnected.

I want to thank everyone for the info, for those of you who have had this happen, it's a weird thing to stand outside the vehicle and see it trying to start, isn't it? Anyway, I'm gonna try the relay and go from there. I'll follow up if it works.

Just as a follow up, I changed the starter relay and it seams to have worked. But because it is an intermittent problem, I wont' know for sure for awhile. Thanks for all your help everyone.

My car did this once (It's a Ford too) turned out to be the starter relay. I don't know if your truck has one but if it does that's the first thing I would replace.

It takes approximately 9.5 volts to start a car. If you hear a clicking sound, your battery is not putting out enough voltage. Your radio, headlights, etc., will all work, so you will think that your problem is your starter. NOT SO. Either you have a weak battery which need charging, or the most likely culprit are your battery cables. Most people will look at their cables and if they LOOK clean, and don't see any white corrosion build up on the terminals, they believe the battery terminals are making a good contact. Once again - NOT SO. Those terminals and cables are lead. Lead is a shiny metal. Scrap the top of a battery terminal and it will shine. That darkness on the terminal you scraped off is also present between you battery terminal and cable, and will prevent a good contact. All it needs is to cause a drop in voltage to your starter and you will hear a clicking sound from the starter. Get a good battery terminal and cable cleaner at your auto parts store. The type with the wires inside that will really make those terminals and cables shine. Once you have cleaned them, your battery will put out max voltage. If you still hear the clicking sound, take your battery to an auto parts store and they will check it. It may not be holding a charge or you may have a dead cell. However, DO NOT try and clean your battery terminals with Baking Soda or Coca Cola. I've worked on cars for over 55 years and all that does is clean the OUTSIDE of the terminals - NOT the connection between the cable and terminal. So many people run out and buy a new starter or battery when it is really the connection itself.

Without proper diagnostics we will never be able to tell you exacts, but with the problem that you re having, it sounds an awful lot like your ignition switch has gone out/shorted.
start out by testing the wiring to the starter, ensuring that all wires are in good shape and properly connected. You will have 1 wire that goes to the ignition switch, test for electricity also.
Switch off, test for power to the switch, proper amount and test for power to starter/relay.
These 2 tests should get you in the right area of the problem.
Hope this helps and good luck

its definately your starter relay if it were your ignition switch then the engine would start, but since it is turning over without firing then that says the starter is getting power and the ignition system is not. replace your relay and have a nice day. its located on the right wheelwell, its what your positive cable from your battery connects to.

Tap the starter with a hammer while it is trying to start. If it stops its the relay.

sounds like your solenoid is bad, it caused my 1986 F 150 to do that, i would replace the solenoid first then go from there on about $10- $15 at any auto parts

Sounds like the book by Stephen King think it was called Christine.
