dont bother with the fuel line thing, because if your engine is screaming its little head off its no good because you have to get the body off etc. if you put your foot on the fly wheel or the exaust it will cut off no problem
BTW: be carefull when your doing the fly wheel thing because once when i was about to do it i lifted the car on its side and all this oil and fuel residue blew into my face lucky none of it went into my eyes[:'(]
