If anyone can help on what might be the culprit. My check engine light is not working at start up, which means that it has been somehow disabled. Any easy things to look at?

1. Burnt out bulb?
2. Somehow unplugged under the dash or in the engine compartment?

Thanks,

please don't post multiple thread. Frist you need the wiring diagram of your car and donnor (mustang) then look at your PCM for your mil signal. Hope that help...

 

So sorry, my previous thread asked for advice on a mechanic, while this one is seeking advice to a specific electrical issue. Thank you for the response, it is appreciated.

If i was you, i will check all my wiring. It's long but it's worth the effort.
