Changed oil car won't start!

[Eyedoc3]

I changed oil in my 2001 C4 and now it won't start. I had key on to listen to radio while draining oil and jacked up car with all wheels off ground. Is there a computer glitch or way to reset to start car? What happened?

Thanks in advance

I would check the battery voltage first and foremost.......

Found answer-disconnect battery and left overnight- computer resets all ok

I changed mine on my 2001 C4 Cab around 60k a few weeks ago and ended up with the engine running rough. I even had the CEL come on. Apparently the seal for the oil cap got compromised and threw out two codes which typically together mean some kind of air intake vacuum leak.

I guess I could have solved my Cel issue by disconnecting the battery also

I have a new oil cap O ring waiting for me at the dealer and meanwhile I put some white lithium grease on the old o ring.
