I have 2 BF150 hondas. The other day we ran out of the harbor 28 miles and the motor ran like a champ. We stopped and anchored and when we got ready to leave the motor would only crank. Checked everything, bit no start. I took it to a certified Honda mechanic and he checked everything. Compression is perfect, fuel pressure, high and low perfect as well. Has fire and getting fuel. Still no start. Swapped brains, crank sensor, and several other sensors. Nothing. The alt. light at the helm doesn't come on either. Fuses are good and found no probs. in the wiring. If you throttle it up it will start but no idle. It die's. At a loss. Can anyone give any suggestions??
