No start
 

I disconnected my vacuum line from the vacuum reservoir when removing my front bumper today. When I bolted the bumper back up and reconnected the vacuum system I went to start it up and no joy. I was playing music during the long process and thought my battery was dead, tried to jump it but it still didn't work. We did notice that it was really really close to starting when we were jumping it, but when we weren't jumping it, the engine wasn't even close to turning over. So is it a vacuum problem, or a battery/alternator problem? Thanks

Sounds like a battery to me if it was trying to fire up when jumping it. Just had the same problem on my buddy's Jeep last night ironically.
However an open in the vacuum lines I do believe would cause it not to start too. Might want to make sure they are all nice and snug on!

Yea, that's what i was thinking. I'm gonna take it in to advanced auto and have them charge it full tomorrow. I also already check all the vacuum connections too.

If you've a multimeter, you can always shoot the battery as well to do alittle DIY troubleshooting. Check the fluid levels too. Good luck!
