93 t100, check engine light will not come on. I have checked the bulb and pulled the ECU fuse to reset CEL, still nothing. Any input? I just want to be able to check my engine codes that I'm sure are there, im just not able to see.

Does it come on when you turn on the ignition before starting the engine? I think OBD1 was the same as 2, where the light came on for a few seconds to show it was functional (self test).

Welcome to the forums! :)

Does yer engine start at all? Have you checked yer fuses in particular the 15A EFI fuse? It should be located in the engine bay fuse box. This fuse provides power to the ECU and fuel pump. If it's blown, you could have issues with yer fuel system like a clogged fuel filter. ;)
