My brother and I just got done rebuilding this engine. It fired right up and idled perfectly, he then purchased faria system check gauges and had to rewire the main engine harness to the control box. Now, the engine cranks, got a couple of chugs, but thats it, it won't start/run/idle. The guages work properly, engine cranks, we have great spark, so what am I missing ? Thoughts anyone. VRO related? System-Check related? . Please any and all ideas welcome.
