ok i pulled the plugs and checked for spark. all 4 have spark. when i turn the key i can hear the fuel pump turn on. all vacum lines appear connected, all intercooler piping is secured fine. when i was checking the plug closest to the firewall it shot fresh gas out of the engine. any ideas of what it could be?

Did the car overheat or get hot when the white smoke was pouring out? If you have fuel and spark at all cylinders you probably don't have compression. White smoke = coolant burning so I'll guess blown headgasket.

the car didnt overheat. the thick white smoke that was billowing out smelt purly like fresh gasoline. i think its somethin electrical because it was literally one sec the car was runnin perfectly fine and the next second it was all fukd up. it wasnt a gradual thing at all

Unburnt fuel should be black.

Anyway, did you check for codes? All you checked was spark and a cylinder had fuel in it. You need to check codes and check compression.

It's not firing on one cylinder. Explain how you went about checking the spark.
