Sounds like your fuel pressure regulator is bad, or the computer is turning on the injectors on constantly. I would also check the wiring harness for the fuel injectors.

What is liquid locked in the cylinder.

It's when water or coolant gets into the cylinder, causing a hydro-lock condition. Water won't compress like air does in a cylinder. It will lock up the engine when the pistons won't travel full length and the crankshaft won't spin.

Leaking head gasket allowed coolant into one or more cylinders. This is causing hydro-lock. Remove all spark plugs and crank to see if coolant comes out. If it does, then clear it out, reinstall spark plugs, use Blue Devil sealant in cooling system. Start and run per instructions by Blue Devil.

Cranks won't start

smelling gas like you are is a bad thing, engine must turn over to fire injector. sounds like flooding ( possible ECM/power computer bad ). Before condemning the computer pull all spark plugs, disable ignition coils, then try cranking to see if engine will turn over. Be carful if hydro locked gas will be pushed out the spark plug hole/s

My 2000 dodge caravan wont start after going through a flood what could it be?

the ignition wires will need to dry out, if they get soaked it will not start unless you have good wires, when they start to get old they are more prone to not working when they get wet.

this is providing the starter cranks the engine and it did not hydro lock from water getting into the engine.

Hydro lock

If you hydro-locked it,the damage may already be done.Let's hope your'e lucky.Remove the spark plugs,thoroughly drain the oil and refill.Remove the fuel pump relay,then crank the engine.Hopefully,the cylinder that filled with water will force it out through the plug hole(s).Put a few drops of oil down each plug hole,then reinstall the plugs and fuel pump relay.Start it up.You will know right away if there is damage(a bent connecting rod will cause the piston skirt to hit the crankshaft-will make loud noise).If it sounds OK,your'e probably in the clear.

My dontn atart,because get in water inside motor,and maybe,the computernits broken too,or maybe the plugs its borne.

If you got water inside your motor, it sounds like you may have hydro-locked, meaning water has filled one or more of your cylinders, not allowing the engine to turn over because the pistons can't compress water. Pull out all your spark plugs and turn the key as if you were going to start the car. If you see a bunch of water shoot out of the spark plug ports, then it was hydro-locked. Put the spark plugs back in and try to start the car. If the car starts, listen for clicking, ticking or banging from the engine. If you do hear a lot of noise turn it off immediately. Unfortunately, hydro-locking your engine can potentially cause a lot of damage to your engine. You could have bent a piston rod or a valve. If that's the case, you should take it into a shop to have it checked out.

Good Luck!

Flood damage

If Engine Was SUBMERGED you must Change oil Remove All Spark Plugs Before you try to Start it AS WATER IN Cylinders While trying to Start Could Cause HYDRO-LOCK and Bend Piston Rod / Push-rod / Valve stem . You Must Make SURE Nothing ELECTRICAL is WET USE Compressed AIR to Dry Everything, Make ABSOLUTELY SURE All IS Dry and FREE of Excess Water. EVEN though you DID try & Start it Still Fallow these Instructions they WONT Hurt it for SURE. Hopefully It Did NOT Get Water Inside ANYTHING CRITICAL and It Lives Happily ever After. I ALSO Hope this Helps you with your Problem. And Please Dont Forget to RATE Me, Thank you!
