Why did you replace the crank sensor if it's running? When the Check Engine light comes on, there will be at least one diagnostic fault code stored in the Engine Computer. Most auto parts stores will read those codes for you for free. They will lead you to the circuit or system with the problem, not necessarily the defective part.

Also be sure the gas cap is tight. The system is pumped up to 2 pounds of pressure while driving to check for leaks.
