In this episode of Pete's Garage I walk through diagnosing a cutout issue on a FiTech EFI system. The vehicle is a 1969 Camaro Z/28 with a 383 stroker, big cam, aluminum heads, 10.5:1 compression, and a Muncie 4 speed. I go over checking the inputs to the ECU to determine if they are the cause of the problems. This applies to any aftermarket or factory EFI system. Luckily FiTech uses many sensors that can be purchased off the shelf at any auto parts store.
