Hello my friend,
I believe you have either a broken "rack and rod" or an electrical ignition switch that has melted.
The rack and rod consists of a gear that moves a rod inside the steering column. The rod moves an electrical switch that tells the starter to crank or stop cranking. Not sure about your truck, but Ford cars in 87 had many problems with melted ignition switches that would stop moving in either the cranking position, accessory or somewhere in between.
Good luck : )

You replaced the starter and its grinding how do you fix that?
I replaced the starter but it makes a grinding nose how do i fix it
Does 1996 Honda Accord has a cranking system?
Yes, it has a cranking system called a starter.
1996 ford aerostar not cranking and changed starter and nothing is still happening what could it be?
it could be your starter selinoide which should be in the engine compartment near the battery and the big waire from your battery goes to it!
What is the first sign you need to replace your car starter ?
An automotive starter is a high torque motor that generally works until it just quits. Heat generated from hard (long) starts shortens the life. Mis starts, grinding teeth, slow cranking and spinning free are indicators
Why does a cranking motor have an unusually high amperage draw accompanied by a slow cranking speed?
The armature bushings inside the starter motor are probably shot. Time to replace the starter.
Why does a 1994 Topaz with 120000 on the engine make a grinding noise when starting or it wont start at all?
That is a broken/worn teeth on the flywheel or on the starter pininon gear. That is why you hear a grinding noise. It's the starter turning without being able to engage.From what you describe I would suspect that the starter is not fully engaging. I'm assuming that the grinding noise you hear when you try to engage the starter is INSTEAD of the engine cranking. If I assumed wrong, ignore the following:Pull the starter, check the flywheel for excessively worn areas. Most of the time the flywheel is ok, it's just the starter. If you feel comfortable working on the starter, just get a new bendix and clean up the rest of it. Any time you disassemble a starter you should replace the bushings and brushes. Never remove the starter with the battery still connected. Remove the negative terminal from the battery before you attempt to remove the starter.
Why does your 1999 Ford 150 truck make a grinding noise when you start it?
Defective starter drive? Broken tooth on flywheel/converter? My guess would be either the flywheel, or if the starter has been changed recently, maybe there was a starter shim that was not put back in.
A cranking motor has an unusually high amperage draw accompanied byslow cranking speed?
most likely a failing starter
Can continued cranking overheat your starter motor?
more than likely u fried the starter solenoid
Cranking torque for starter?
In general starters do not have torque specifications. You will want to tighten the starter as tight as you can without breaking the starter bolts.
How long do starter last on rotary engine?
That all depends on if you abuse the starter by cranking too long. I have 170,000 on original starter.
Can a voltmeter be used to measure voltage in and out of a starter motor?
Voltage flow into a starter motor, never out of it. Use the voltmeter to measure the voltage at the starter motor before starting to crank and then whilst it is cranking. (Before cranking, the voltage appears across the starter motor relay only.)
