I replaced the battery and cables. Engine cranks but won't start. on 1998 Ford Windstar

I've checked with a CodeScout 700 code reader and there aren't any codes showing. The engine will start with the code reader plugged in and seems to run fine but still won't start when I unplug the reader. With the engine running there are still no codes. I've checked with a test light all fuses under the hood and the dash. All check okay.
