Hi Rodney. First know that nearly all spark plugs sold today are already gapped to the proper specification. You shouldn't have had to change them. Can you clarify what you mean by your car won't stay cranked? Cranking is the process when you turn the key to the start position. If it will not crank, start first by verifying proper voltage at your battery. Use a multi-meter to do that.
