I was stuck in a parking lot sitting there for 30 minutes waiting impatiently for it to start when I popped the hood and pulled the fuse out for the ECM. I sat around for a couple minutes and popped it back in, turned the key and the dash looked normal and on the second turn it started right up. Then I find that my airbag light is on...
Am I right in thinking it's likely the ECM at this point? Can software in these things get corrupt and start doing funny things like this or would it need to be replaced vs reflashed?
I think its the pcm or whatever it is under the shifter bezel. Mine used to do that cause my idiot brother spilled something down there. I used to get all those boxes and it would pop out if gear on the highway.
