A few days ago, one of my headlight bulbs went out. After taking the headlight assembly out to replace the bulb, and reinstalling the assembly, the car will crank but barely won't start. I've tested the battery and it's fine. I've also checked for blown fuses and they are fine as well. I have also made sure it's not the immobilizer preventing it from starting. I believe the issue has something to do with the headlight replacement given the timing, but I'm kind of just at a stand still for the time being. Any help would be appreciated

 

Can you jump-start the car? I'm wondering if you drained the battery too much while testing the new bulb. I'd double check grounds/connections too, though it sounds like you did this.

 

I have tried jumping it with no success. I'm sure I did somehow cause it, just not sure how. I'll double check all of the connections and hope that I find something. Thanks for your reply.

 

Recently I've been having that happen. Check/ clean your MAF sensor. If that's it, think about picking up a new one. There's also the crank position sensor. But that would start after a few seconds of cranking..

 

I just checked the MAF sensor and it has no visible dirt or oil on it. Overall it looks very clean. I did however find this wire that runs through the firewall right behind the brake actuator. Not sure if it could be related, but I can't find anywhere that it would connect to

 

It's worth mentioning that the MAF is super sensitive so you might not see any dirt in there. MAF or brake parts cleaner is worth the time.
