So, I was replacing my crankcase vent valve. While disconnecting the electrical connectors, I thought that they're all different and paid no mind to which goes where. After all is done, I put everything back and tried to start the car. Well, the fuel pump made cluck cluck cluck cluck noise, and of course, didn't start. Dissecting everything, there were two plugs switched. I think something is fried. Anyways, moral of the story is, label everything. It was such a stupid thing that will cost me dearly.
