Alright is it just a matter of replacing a bulb? I’ll look into this next hahaYou need to verify this, If you have a good bulb, this means ECU is not running bulb test, wich means ECU may be faulty or could be wiring to cel
All of this weirdness started after I rebuilt my throttle body.
If it is my ECU, could my truck have been operating with a faulty ecu prior to this or would I have had to do something to brick it?
