Starter Problems
I have a 1979 Ford F-150. I was having problems where it wouldn't even attempt to turn over. So I replaced the starter, solenoid, all starter cables, battery and battery cables. So here is my problem now, it will start, but the starter stays engaged. What is going on here?
Thanks

Start the engine and if the starter sticks pull the "S" wire from the solenoid. If it stops, then you have narrowed down the starting circuit.
If the starter continues to spin, then the solenoid is toast... new or not.

How are your grounds?
Negative cable directly to engine block. Make sure where the cable contacts is clean and free of paint.
Ground strap from block (usually intake manifold) to firewall.
Another good thing to do is a ground strap from block to frame and a another from the frame to somehwhere on the bed.
And you can get more nuts by running a 6 or 10 gauge cable from frame to the passenger inner fender apron.
Either the solenoid is getting fed constant voltage from the ignition switch or is getting stuck from overheating (poor ground WILL cause this)

It means you have voltage either going thru the ignition switch (which means the switch is bad) or the wire is crossing somewhere which can be pretty likely if your wiring harness is all hacked up from previous owners.
Usually to help narrow down the problem you borrow a known 'good' switch and see if the problem is gone or if the problem persists you'll need to start tracing wires... Fun Fun

I had a similar problem with my '74 F100 390. I replaced the soleniod and it helped for a little while, then started to do it again a couple days later. So I swapped in another soleniod and didn't help. Changed out the ignition switch, didn't help. Swapped out the starter, didn't help.
Ended up, some idiot (me) painted his engine bay and didn't have a good ground on the back side of the soleniod. Didn't relieve the soleniod grounds its self threw the mounting screw. I would first start there. If that isn't the trick then go to your local Ford dealer and get a Good soleniod from them and not the crappy ones from Napa and the likes.

I still can't find the problem with this. For right now, would it be okay if I just started it everytime and after it started I disconnected the starter from the solenoid? It seems to run perfect once I do that.

You could disconnect the wire form the s post completly, and make sure to cover the hot end of the wire good so it wont touch anything ( not doing this can cause an under dash fire). Get a momentary push button switch, run a hot form the hot side of the solenoid to the switch, run a wire to the s terminal on the solenoid, and use the button as your starter engage. Could be permanent, if done nicely, or just a temp fix til you could figure out the real problem. Turn the key on, hit the switch to engage the starter, and let it rip.
