Clutch throw and starting
When I start my '89 F-150 4.9L 4x4 4-speed, I have to push my clutch hard to the floor before the starter will engage. It feels like I'm going to shove it through the floor. It's so bad, my wife can't do it sometimes. When I'm shifting gears, I don't have to push it down so far, about 1/2 to 3/4 of the way down.
Is there an adjustment I can make so I won't have to throw the clutch so far? (it hurts my toesies)
Thanks,
Ben G

There's a switch that only allows the starter to engage when the clutch pedal is down. On my '95 that switch is under the dash on the rod that goes through the firewall into the clutch master cylinder. Switch may be worn out, housing cracked,or whatever. Replace or maybe can be eliminated and just hook the wires together so it will start w/wo clutch depressed. Now somebody will tell me not to bypass this switch as it is a safety feature, but my '77 didn't have it and I survived--you just have to have enough brains not to start it in gear with the clutch engaged.

My 88 should be pretty much the same as your 89.
The interlock switch is on the master cylinder shaft just above the gas pedal (yes, I said gas pedal). there should be a 6 wire grey connector plugged into a black cylindrical sliding switch.
Disconnect the wire harness and remove the switch by removing the door clip on the top. It's hard to describe. After you get it off, look at the slider and see if the contacts are worn. Clean them up and regrease or replace the switch assembly.
The only adjustment you can do is if you extend the contact pad area or just jumper the two interlock wires together. I think they are black and red/y but I am not sure. Get out your manual.
