Please clarify. It would "try" to crank? Either the engine turns, or it doesn't when you cycle the ignition key to the "start" position. Do you mean it turns SLOWLY? Are you sure your batteries, and your connections are good? If so, it sounds like your starter is drawing excessive amperage, and needs to be replaced, or the engine is tight. Has it ever hydrolocked before?

the engine turns when you cycle the ingnition

[chvylac]

and the engine has never been hydrolocked before

also the power drops down around 8 right when u turn the key to run before you turn it to crank

if batteries checked out good,connections are good,starter relay is good,then its your starter.
