99 ford ranger. Wouldn't shut off. I pulled pcm relay to kill engine and disconnected the battery. This morning I replaced the ignition switch but ignition was still live in the off position and would not engage the starter to start it.All relays and fuses are good.

Even though I bought the vehicle new, there was an aftermarket security system installed. The system had a bad diode, so i removed the system and reconnected the factory wires.

An ignition switch probably isn't the problem, because the vehicle probably wouldn't shut off if the switch were the problem. When you turn your car off the battery is not being drained any longer from the switch unless the vehicle is unable to shut down.
The other possibility that will definately cause a battery to lose juice while not running is a faulty starter sellinoid. When these sellinoid's, (may not be spelled correctly, sorry about that) are bad, the motor is turned off but the battery is still drawing current, but the engine is not running to allow the battery to recharge.
It could also be a bad battery. Check your battery cylinders by removing the plastic covering and checking the water level in the cells. Dry cells in a battery will not allow a jump.

I will try to help you. You are correct about the starting fluid, if it has fire starting fluid should do something. So the problem must be either no fire to the plugs or the timing belt is broke.

Check to see if the plugs have spark. If they do not, then get with the Autoparts store and ask if your car needs a Ignition relay to run. Then ask if your car takes a rubber timing belt. If your car does not have a rubber timing belt try the Ignition relay. If you do have a rubber belt check behind the shield in front of the engine to see if the timing belt is broke.

The timing belt is different than the serpetine belt that drives the pulleys. Cars with rubber timing belts have both belts. Should your timing belt be broken it is not an expensive repair. But you will need to details on replacement of that part.
