I've got a brand new fh791d 29 DFI water cooled kawasaki engine. I hooked up the starter to crank the engine over and I'm not getting any spark. My fd 750D engines puts out spark on its own when you crank the engine over and no wires connected. I've checked the coils and adjusted the air gap but no spark. According to the wiring diagram it looks to be the same as the 750d except it has the digital fuel injection box on it E.C.U which I believe shouldn't affect my spark. Any ideas would be greatly appreciated.
