Hey, okay, I did the DX to Si swap.. I got spark... I got fuel... no ecu codes, everything is hooked up in the right place... but the engine won't fire... It cranks over, sounds healthy, but she won't go.... the engine was pulled out of an 89 Si from the wreckers with 7o,ooo Km's on it. The engine hasn't been started in a while, but it turns over easily... I have tried using engine start to get it going and it seems like it wants to start going, but it doesn't pick up. Now, has anyone had this problem, or any suggestions that I should do to try and fix this problem???
