great now the car doesnt start

[n00b on demand]

This car is driving me up the god damn wall!!! Its been sitting in the garage for basically 4 days with only having driven 2 miles on it because of the exhaust issue. Now the car doesnt wanna start. More than enough juice from the battery but no start. This always happens when the car doesnt get driven for a few days...its always hard to start but it always eventually starts. This time it won't. What the hell do i do now? I had put some gas treat ment and isopropyl in the tank to prevent gasline freeze up. I have a little less than half a tank of gas in there right now. This is really pissing me off....my new insurance starts monday and what a way to start...with a tow to the shop
