My truck quit running last night and would not turn over the motor - I do not believe it is seized - it had plenty of oil. The battery is still strong and a jump made no difference. It seemed to me that the belt was stuck. My mechanic told me that I needed a complete new ac system and the pulley that turns the ac system has been making some weird noises. Could the ac system - which has not worked for 2 years have the abilility to freeze and stop the engine {because of the belt attached] from turning over?
Re: My truck quit running last night and would not turn...
Yes, it can. Anything with a pulley and a bearing can seize up from the air pump, to the alternator, to the idler tension pulley, to, yes, the a/c compressor.

If you drove it without oil and it heated up enough you seized the engine and you are out of luck. Engine rebuild or replacement is your only option. Check this out with a mechanic first before getting crazy though.
Try measuring battery voltage at the starter motor. Should not drop below 12V when cranking.
If does pull plugs and see if you can hand crank. If more is really tight try some very light oil in cylinders for a couple days and see if anything loosens up.
SOUND LIKE OIL GOT LOW ENOUGH TO LOCK UP THE ENGINE.THE ONLY THING YOU CAN DO IS TRY TURNING ENGINE WITH A LARGE SOCKET 1/2 SOCKET AND 1/2 SOCKET WRENCH.IF MOTOR WONT TURN ENGINE IS LOCK UP FROM LACKING OIL IF ENGINE DOES TURN AFTER USING THE SOCKET THEN.USE A CODE SCANNER TO CHECK WHAT CODE SETTING OFF REDUCE MOTOR POWER.
Sorry that happened, if you didn't start the motor right after you changed the oil, it's that the any oil that was left in the motor bearings would have drained out leaving them dry. Sounds like you spun a bearing when it started. You could pull the oil pan and look at the connecting rod ends, if any are blue, the motors ruined. I'd start looking for a new motor.
First try boosting car with extra battery, attach posotive cable of booster battery to posotive cable of your battery and negative cable of booster battery to engine block, never to negative post of your battery, If it still does not turn over,Try turning over the motor with a socket and stong arm attched to crankshaft bolt. It could be that your motor has seized due to lack of lubrication
losing water for months, but no eveidnese under car. Either being blown out exhaust or it's in the oil. Pull out oil dipstick and check if oil if foamy or too thin. That would mean the presents of coolant in the oil. And that happens from bad headgasket.
This could keep from starting depending on how freezing.
The starter for one. Is it not turning over at all or you hear a clicking noise. did the motor just quit and will not restart. consider that the motor could be seized up but that's a last possibility.
