sounds like no compression

This may be due to a starter problem. Sometimes the starter will turn, but the solenoid does not shoot the shaft out into the starting sprocket. However, if you think it is a compression problem, get a compression test done (very simple). If it is the compression, check the following: 1.) Valves(one may be bent letting all the compr. out) 2.) Head gasket (may be blown) 3.) O rings(on the piston. AKA piston rings)

see the above question.
