The point is the problem needs to be diagnosed. Diagnosing a problem does not consist of replacing random parts until a problem is fixed. It's entirely possible that there is an issue here with broken wiring, shorted harnesses, or some hidden damage from the previous owner that will not be solved by simply attaching new parts. Shotgunning parts is never the way to fix a vehicle. Sensors rarely go bad, and if they do you'll typically get a discreet OBD code that will tell you where the problem is. Seriously, taking an old non-running engine with unknown history and installing a pile of new parts on it is simply the wrong approach for a whole spectrum of reasons, and any competent mechanic would tell you that. If you used a scanner, you'd know in a second if you were in limp in mode, and you could quickly pinpoint values that were out of expected ranges. If you have multiple PIDs that are out of range it's obviously not a "bad sensor". You can buy very capable scan tools in the sub-$400 range these days.
Don't ever, EVER, believe what a seller tells you about a vehicle. If they're not lying, they may not even know. I used to buy a lot of "fixer uppers". I bought a cute Audi one time that "just had a blown head gasket". Know what was actually wrong? The engine had been massively overheated, the head was cracked in a hundred places and had been taken off and reinstalled with silicone gasket maker. The exhaust valves were melted. Coolant had blown out the intake and filled up the air box and got into the fuel distributor, which was seized. The exhaust was full of coolant gel. It took weeks of work to get that car to run. I've learned to always expect the worst, because that's usually what it is.
