Default Electrical Issues UGH!

I just got my Cruiser back after the shop had it since April, yes I said April, and now its worst then before, The nice gentleman replaced everything except the wiring harness, Like I asked him to do as suggested by this forum, after $254.97 it will now not even turn over, had 2 front flat tires, dead battery, and a bunch of bolts sitting in the engine compartment. Needless to say, Im lividly ticked off. Being from an electronics back ground, I decided to try to walk out the electrical issue, I got 12v across the battery, (After a full overnight charge),
12v to the starter, but only 6v to the post to the fuse in the engine compartment block post, There is 12 to the connector, but when i test to the post that feeds into the fusebox itself, it reads around 6.7v would this stop the the starter from turning over? The starter doesn't even click. also could that have been the isssue in the first place where it would crank but not start?

Thanks!

Battery Cables -terminals immaculately clean? tight? I doubt very much if the starter would do anything with 6 volts.

What on earth could have been replaced for $250??? That doesn't buy much and certainly didn't buy you a new battery.
Not clear where you are measuring, but basically there should be either 12V or 0 at major cable points ( signal wires can have lots of voltages, 5V is common).
You ask if you have the same issue - well, before starter turned, now it doesn't, so you are worse off..

Disconnect the battery. Loosen, remove and save the two nuts (bolts) fastening the positive cable connection at the under-hood PDC. Move and clean to shinny, the cable ends. Reconnect everything.

Possible corrosion in many places; try removing, cleaning up and replacing the 40 amp main fuse in the PDC. May as well do all fuses and relays.

If then problems still are, I'd suggest removing all needed for access to unfasten, move, open and look under the PDC unit for signs of damage.

I was testing random areas around the engine that are major 12v areas, From the battery to the 12 positive on the starter (12.57v), it like that if you try to start or not, and to the fusebox in the engine compartment cable reads 12.57 but if you touch the post it drops to 6v, like the contact from the wire to the post has a 6v loss. The things replaced from him was, Cam shaft sensor, ignition packs, plugs wires, I bought a crankshaft sensor and PCM, that he installed, I guess i need to get under and check the voltage to the solenoid.

The battery cables on the battery are fine, Head light are nice and bright, dome and dash light are bright, tail, break, turn and reverse lights are fine, Radio work, so I don't think its a battery issue, Im really thinking it has to to do with that 6 volt read at the fusebox, But I am a computer tech not a mechanic.

got 12.9 to the center post in the picture, still nothing on the starter. how do you jump a starter using the terminals to make sure its not the starter?

.
"ignition packs" ????? = Coil ??

Were spark plugs replaced along with the wires?

That's all good, but none of that is starter-related.

PCM needs programmed, was that done? was it new? or out of a used car?
or so called rebuilt? What Co did you buy it from?

New and programmed to car's VIN and mileage, I really don't think the old one is bad, Is it like a computer system/hard drive? I mean i can take a hard drive and motherboard, pull it into a like pc and it doesn't know the difference. it will run as long as everything is the same.
