g 1000-vista

I have a g 1000 vista It has been running beautiful. I shut it off one day and now the engine wont turn over- siezed. what would cause this? and what do I do about it?

Sounds to me like it hydrolocked some how. Is it a diesel?

Might want to post this on the MM forum as well.

I'm guessing water or fuel got in one of the cylinders (bad)or your starter or starter drive died (looking better than water in the cylinders eh?) or maybe even some accessory like a alternator/generator, hydraulic pump, water pump, power steering pump or injector pump has seized. Try to turn the motor over by hand with a wrench or socket if a gas tractor pull the plugs and see if it'll turn over, if a diesel pull the injectors OR maybe consider removing the starter and accessory belts and accessory device to see what might be preventing it from turning over before you pull the injectors.

I say this as I remember a tale one of my Uncles told, he ran an auto salvage business and purchased a really clean Monte Carlo for cheap because the engine was seized. They pulled it into the disassembly bay and removed the front clip, radiator, doors, radio, trunk lid, brake drums & rotors, calipers and such. One of the guys was screwing around with the engine getting ready to remove the alternator and other motor components, the more he looked the more he wondered, pulled out his jackknife and cut the A.I.R. pump belt, the engine wasn't seized anymore, but since the car was already apart it went for parts, had they figured it out before they took it apart they would of installed a new A.I.R. pump and resold the car.

If it is seized you have three options, Rebuild/repair the engine, install another engine or part company with the tractor.

It sounds like you have liquid in one of the cylinders. When you said you shut it off one day then tried to start it one day how long was the period in between?
You can loosen the injectors from the head, not the fuel lines, and if you have a way to turn the engine over by hand I mean like a flat head screwdriver at the ring gear it should force the water (most likely) out of that cylinder.
Sounds like a bad head gasket or a cracked head.

Are you sure the engine is seized and it's not a problem with the starter or bendix, etc.?
