Update:
Timing belt was SHREDDED.
Multiple teeth missing in multiple sections… completely severed, and 75% or so of the timing belt had been chewed up and deposited inside the timing belt compartment as greasy fibers and mangled particulates. It was pretty brutal.

Since the crankshaft was spinning freely (via the starter), and the camshaft was not connected to it, the crankshaft position sensor was reading change, and the camshaft position sensor wasn’t…(P0340)

Had it in drive, when the battery was pulled.
put it in neutral to winch it into my garage, and put it up on jacks, then put it in park. When the battery was still reinstalled, I think the computer just remembered the last position it was in before the battery was pulled… therefore Engine speed and transmission speed were intolerantly different (P0700)
put it in neutral and back to park… tried to start.

Don’t know about the fuel level thing…
I’ve since cleared it, and it hasn’t come back.

Replaced timing belt, lined up timing marks VERY carefully…
cranked it, and let it run for a few seconds… very rough idle… (probably because I didn’t have any oil in it at the time…)

will test compression, again, after oil, antifreeze and power steering fluid have been added back into the car…

Voltage of battery reads .5 volts after being charged by another car for 20 mins, and charged on a battery charger for another hour or two… sounds like I’ll have to replace it…

Automotive controls and signals are a weak point for me… I really don’t have any idea what the hell I’m looking at…

So, before I finish the tear down to the timing belt, Can someone coach me through a testing procedure for testing the Camshaft Position Sensor signal? I have a multimeter, and a working knowledge of electrical safety and electronics…
Thanks in advance

Thanks for the quick response. I’ll do my best to reciprocate!

Compression test says 0 compresion on 3 cylinders triple checked connections, and readings, and very low compression on the other 3 (50 and less) not next to one another. So either timing is off, or bent valves?

Pulled the intake manifold, watched the valves move during cranking, so timing belt is intact… maybe off a tooth or two? Does that make sense? I feel like a jumped tooth or two is not very common, and that If my car stalled from a timing belt slip, the valves are almost definitely bent… which is there a simpler explanation?

Battery is charging overnight… will test voltage in the morning.

I’ve begun disassembly to access timing belt. Gonna take a couple days before i can pull the covers off… limited time to work on it, and Tbh, I’ve never been this deep in an engine before… kind of intimidating…

Are the typically more than one camshaft position sensors? How do they read position? Is there some way to verify the sensor is reading correctly? Thanks, sir!
