Recently I purchased a 2004 Subaru Wrx, the motor was blown, so I (owning a mechanic shop) did a motor swap on it. (I purchased an ej20, which was twin turbo, but converted it to single turbo) Everything fit perfect, and everything is in right. All wiring, and fuses, etc. The motor turns over, but it wont start completely. If anyone has a clue why, and would help me, it would be appreciated. Thank you.
