I changed alternator, have a new battery. Truck started when battery first installed, ran for a bit but wouldn't restart once turned off??

I replaced key cylinder , now I need new keys programed . I didn't realize this could be so complicated . I don't have a lot of money . I don't understand why you can buy the cylinder replace it but you can't program the keys to it . Please help

I have an elbow that comes out of the lower thermostat housing and connects to the lower radiator hose. There is a line that runs out of the air compressor and right across the elbow. Ive already loosened the line but Im having trouble getting the elbow to clear everything that is still in the way such as the bracket that holds the top pulley which sits next to the air compressor. Surely I'm not going to need to disassmble the entire front end just to get this one small pulley screwed in. Im replacing it because I had a pin hole leak. Can anyone help me? I can describe everything needed to know including part numbers and schematics. and even photos. Im getting desperate here.

Any way runs rough when cold worms up smoths out but still has small miss like carb. With no choke

I was driving down the road headed home when I noticed a light sounding knocking noise that knocked faster when I sped up and slowed when I slowed down. At home I put my truck in neutral and revved up the motor and the knocking noise went up with my rpms. It seems to becoming from around flywheel, clutch, pressure plate area. It has a brand New flywheel and pressure plate they were replaced about a month ago and everything has been running smoothly besides it grinds shifting into 2 gear which started right after I replaced everything. Any ideas? Also if it helps diagnose the issue the slave cylinder has been replaced 4 times in 3 years. Once with me and 3 times with the previous owner

Was good for a day, now doing it again. Any help on where to go next?

Like I said, it runs and starts up perfectly once the engine is warmed up. If I turn the truck off and go to start it up half an hour later, it will start up with no problem. But if I wait too long, it gives me trouble. It just clicks and clicks each time I turn the key, and I have to turn the key at least 10 times very fast and hold it on the last turn before it wants to start cranking. When it clicks like this, the dash lights and headlight dim. The battery was tested and is supposedly fine, the alternator isn't an issue because the battery tested at 100% and the gauge says it's charging. The starter was replaced, as well as the battery cables, but I still have the issue. It didn't start doing this until I drove the truck for 8 or so hours straight when I went out of town. I honestly have no idea what else I can check. It takes a jump, and everything points to the battery, but the battery tested fine, and I don't want to replace the battery if I don't need to. What is wrong with my truck?
