Broken coil pack................

From the description you have posted I a summarizing that the engine will not turn when the starter switch is activated , firstly place the vehicle in gear and make sure it has not seized by rocking back and forth( an obvious thing you may think but many miss the obvious ) if the engine is free check your battery connections most notably your body to engine earthing strap and Battery to earth strap . If this is secure and free of corrosion remove the wires from the starter motor solenoid place a bulb across the wires and try the ignition switch if the bulb lights the fault is not there,if not the fault lies in the circuit from your switch to your starter solenoid . Most times I have found the reason is earth strap related either battery side to bodywork or to engine.

I would check to see if the brake calabers are loose or maybe a part of your brake pad has broken away

Is your air condition on? This will increase engine speed. is your truck's cooling system working properly? This may increase engine speed. is air filter clogged? Truck needs less cool dense air than warm air good luck

Seized compressor,

First drain oil at slave cylinder, then remove pipe from master cylinder . disconnect clutch pedal push rod from cylinder , remove bolts holding cylinder to fire wall remove cylinder. wash off any fluid with water as it will damage paint .

ITS A TERRIBLE BIG JOB,WHILE YOU ARE AT IT CHANGE THE RESERVOIR AS WELL. DID YOU REPLACE THE CLUTCH AND SLAVE RECENTLY BECAUSE THEY ARE A RETARD TO BLEED THE SYSTEM AFTER.

Not sure what you have determined the truck is doing If the rpm flairs the trans is slipping & done If it won't go over 40 mph the exhaust converter is damaged & blocked Not much you can do,need professional help

please do not over tighten

i the under dash fuse panel

The trans converter is empty or laying on a slant inside the bell mount of the transmission and if it's rear wheel drive then it could be the driveshaft is put on incorrectly or the differentail isn't any good but it could be simple as the gear linkage is broke or disconnected

it maybe your transmission solenoid!

This sounds like a bad starter solenoid, unless you mean you bypassed the solenoid when you jumped it. If you just boosted the power at the battery, the solenoid could still be bad.
