You need to use an OBD2 scanner, it's not uncommon for the bulb for check engine to burn out if it's been on alot. If you don't want to buy one, you could unplug the map/maf sensor and it will run rich, but it will throw a code. If you do that and it doesn't turn the check engine light on, then you know the bulb is burned out and you need to read the codes. But also I have no idea what is going on with your car because it's striped down. Are you rebuilding this car or what? I'm confused how your seemingly rebuilding a car without the ability to diagnose a simple issue unless you know the wiring is messed up.
