In such cases, the engine can be unlocked by condensing the fuel vapour. For doing that you can let it sit for some time and try to start the engine. If the engine doesn’t start, you can try splashing cold water on the fuel pump and lines. This helps to condense the fuel back to liquid. via
How do you fix a locked up motor?
If you have an engine that seized from sitting for a long time, pull the spark plugs out of all the cylinders. Fill the cylinders with engine oil and let it sit for a few days. Then, try turning the engine over with a breaker bar. If it moves, you may be able to salvage the engine. via
Can a seized engine start?
When an engine seizes and can no longer move, the starter will still attempt to crank the engine when the key is turned. Because the starter cannot turn the motor, the electric wires can overheat and begin smoking, a tell-tale sign of a seized engine. via
How do you know if your motor is locked up?
Seized car engine symptoms:

What causes an electric motor to lock up?
Stressful mechanical, environmental, and electrical operating conditions can all cause electric motor failure. Electrical failures are winding failures caused by an open contactor, bad connection, blown fuse, excessive heat, electrical overload, or broken power lines. via
How do you turn a motor over with a wrench?
The most precise way to rotate the engine over by hand is to place a large socket on the front crankshaft bolt, attach a long ratchet wrench, and rotate the crank. The longer the wrench handle the more precise the movement. via
How do you Unseize an engine that ran out of oil?
Can an engine seized from sitting?
This is how rusted cylinder walls develop: When a vehicle sits for an extended period of time without running, the lubricant coating the cylinder walls thins and drains away due to gravity. Left long enough, that condensation causes rust that can freeze the pistons in place, causing a seized engine. via
How much does it cost to Unseize an engine?

How long will a engine run without oil?
The presence of oil and its distribution is absolutely crucial to an engines continued operation. Engines can work without oil, but the effect is so damaging they are only capable of running for less than 30 minutes until failing - and in most cases, it's a lot quicker than that. via

Should electric motors spin freely?
Does it turn freely enough to run? There will always be a little drag, but the shaft should spin relatively freely. Still, an older motor may have bearings with dried grease. If the bearings are not rusted inside, you can probably work new grease into them. via
