Anyone have some ideas on no check engine light? We been having issues with to much fuel loading this up? Went and bought an obd 1 code reader and found out check engine light doesn't come on at all! And ideas how to fix this problem? Could it be as sim0le as a burnt bulb? Or something more? Any help would appreciate it !

should come on and go off when key is turned on, bulb check.

If that doesn't happen next move is check bulb.

Yes it could be a burnt bulb,a broken wire,a cut wire,a blown fuse, which p.s. a blown fuse is never just a blown fuse it blew because it was doing its job and will blow again unless you find the real problem. What are you working on?

From what I understand and I could be wrong it has to be a filament bulb, leds wont work. So if you went digital the check engine light still needs to be filament.

Try and Unplug temperature sensor on intake manifold by water-neck/thermostat housing and see how it acts then. Also clean grounds on neck bolt/stud.
