    placed old starter because it would turn on while driving.New starter does the same thing, i turn the key to the on position not run position an it just kicks in an will run while the car is running replaced switch on the steering still no luck any thing helps. What about a fusable link on the starter?

    Have you checked all of your wires? Sounds like you have a chaffed wired thats grounding out.

    Yes just finish checking all the wires i have the starter under the hood now ran the wires from below up to the top of motor so i could see what it is doing now when i try to start it, its not sending power to the starter all the accessories come on but no start, this is a new starter i look a the wire diagram an looks like all the wire are in the correct place 3 red in the middle one yellow on the r side two purple on the s side

    Did you check the adjustment on the ignition switch on the lower column?

    yes i checked that its in the lowest slot now but i have been moving it up an down with the key in the run position to see if it may be out of place nothing yet an still working

    Solenoid contacts fused?

    If your solenoid has contacts that stick perhaps it will cause this problem. Have you considered this?

    no i have not only because this is a new starter an the old one was engaging while the car was running

    The thick purple wire goes to the "S" terminal.

    The thinner wire goes to "R".

    If they are crossed, the starter will continue to run.

    Ask me how I know....:Smarty:

    an the yellow?

    The thinner wire Paul is refering to is the yellow. Yellow to R

    ok yeah thats how its ran yellow to the r two purple to the s an there are 3 red to the hot, but on the wire diagram the is only one purple wire an the two small red are fusible links. mine does not have the fusible links is this the problem?

    A picture might be in order here. One fusible link controls the headlights, the other, everything else.

    There is a possibility that the starter is no good. Its not uncommon for solenoids to stick and continue to run after the engine starts.

    Did you get a new starter, and use your old solenoid? Or did you get a new solenoid?
    Like Jason said. Clean the wires good, and post a picture of what you have.

    brand new starter or rebuilt?

    Only 3 things would do that.1)"S" wire is touching the solenoid positive lead,2)ignition switch is bad,3)the solenoid contacts are stuck.
    If you reverse the small leads on the solenoid it wont do anything & it wont hurt anything.
    First thing to do is see if you have constant power on the "S" terminal with key off.

    The solenoid is just a heavy duty relay used to provide high current by energizing a low current control circuit. You need to find out if the problem is control side or power side before you can go further. If there is power on the purple wire when the key is released from start back to run position the problem is in the control circuit. The control circuit consists of the ignition switch, neutral safety switch (for an automatic transmission, clutch switch on a manual), and the solenoid coil. The yellow wire that goes to the solenoid is used to provide 12 volts to the ignition while the starter is engaged to produce an extra hot spark for starting. Once the engine starts the yellow wire loses power and the ignition system runs on about 8 volts. Unless the yellow wire is somehow shorted to the purple wire this is not your problem. Fuse links are circuit protectors just like fuses and circuit breakers. If one burns out power will not be provided to the circuit it protects. In other words, the car would not start at all. Again, this is not your problem. Don't be confused by the extra wires on the "hot" side of the starter. They are just using the solenoid as a connection point to pick up battery voltage. Not part of the starter circuit. If the solenoid contacts fused the only way to stop the starter from spinning would be to disconnect the battery. Most likely, you are going to find voltage on the purple wire when there shouldn't be any. It is a relatively simple circuit and shouldn't be hard to trace. Check the wires carefully where they pass close to the exhaust. I hope this helps. Good luck!

    Another thought- I think there should be only one purple wire going to the "S" terminal. I believe the wire going to the blower motor is also a heavy purple wire. Wouldn't that be interesting!
