so to start with I have a vortex ecu and a gt Thunder manual idle air control. This all started long ago and in the beginning the quad would randomly shut off then not restart for a few hours. After I let it sit it would start no problem, then it slowly got harder to cold start, Now the quad will crank over but won’t start. I’ve swapped the vortex and tried a known working one, tried every adjustment possible on the air control nothing helps. The fuel pump is brand new and I’ve confirmed that it primes. The coil and spark plug have been changed and that changed nothing. The valves have been adjusted and as far as I know no voltage issue, tried several battery’s and have checked for power and everywhere seems correct. Tip over sensor is good. I am completely stumped at this point and am hoping someone can point me in a good direction.
