Got cold, car wont start
 

Hey guys I got a wolf3d wired up in my car. I've only had it running for about a week and last night it got real cold. Its comming up as -1 C on my wolf3d for coolant temp. Yesterday I had it running perfect at idle, pulling about 55kPa vacuum. Then today I go and try to start the car and nope, almost starts but doesnt. I start messing with the coolant temp compansion values and get it running by holding the gas pedal. I had it at about 1500rpms by holding the gas and it sounded like shit, was also making a ticking noise.... So I look at my vacuum and its only at 20kPa...

So after about 3 min running by holding the gas the car dies. I go to start it again and nothing wont even try. By then the coolant temp was upto about 22 C. While cranking I was only pulling in 2-3kPa vacuum, but just yesterday it was pulling 20kPa while doing the same thing.

No I didnt blow the engine yesterday, because I started it up lastnight and let it idle for like a min and shut it off... It started great and held idle perfect.

Does anyone know what could be causing this problem?
