I have a running 91 Olds Custom Cruiser with a TBI 305 that I am using to compare to the truck. It has power to the red wire when the key is turned on, nothing pulses when cranking. Several of the wires have power after it is running, though. Popular opinion is a bad ground, module or coil. I guess since I have already tried new module and coil, I will add another ground.
