Im not a mechanic but i do know one! lol this is what he said!! "see if the fluid is coolant, if the starter is engageing and turning the motor , then it is not seized....if coolant is leaking into the cylinder it can hydrolock and then be seized.....find out how to do a leak down test on a grand prix and see if the cooling system has a leak, before you turn it over to many more times.....if there is no leak then find out where the fluid is comming from. change plugs and do a compression test and start from there"
