I have a engine problem that just developed. I need some expert advice please. I went to work(2pm and 20 degrees out) and all was cool. Went to leave work at 2 a.m today and battery would barely crank engine. It was 4 degrees out. I got car jumped and when it fired up there was a loud constant metal + vacuum sound. I immediately shut car off then started it back up. Same thing. When I gave it gas it was really ruff and fuel smell was very strong followed by blue smoke coming from under the front of car. Smelled like fuel heavily. The smoke(blue) got extremely bad and the sounds I described stayed constant even when I revved it. I don't believe it to be an uppipe leak and the car was not warm enough to be burning any fuel.(i.e-like a leaky fuel line dripping gas on something hot). I had to leave the car and get a ride home leaving the car many miles away. I am going to go back up(an hour away) to the car later today in the light and check it out further. Can someone tell me where to look to check the freeze plugs(worse case scenario). I will check basics. Uppipe for leak but it has been on car for 20kmi w/no leaks . And I will check fuel lines and injectors.(STi injectors stock rail). I have had this car for 2 yrs w/none of the fuel line problems other 02 owners come across. There was no liquids under car. The sound it was making doesn't seem to be the"screaming banshee" sound others describe as an uppipe leak. I'm afraid something cracked in this cold weather. What I don't know is what else to check.
Experts, please help me trouble shoot this. I will have to have car towed back home but will first try and spot the problem where it sits if possible. Not going above 16 degrees today.
Mods are a VF30,STi injectors(stock rail) and full catless exhaust. Been this way for over 10kmi. Has been below freezing for the past week, but not as cold as tonight(last night but I haven't slept yet).
