1991 s10 blazer. I've got 12psi fuel pressure, compression test is good (approximately 145 on all cylinders) exhaust is clear. Fuel return line is clear. Spark is good. System seems to be flooding. Will barely start with one injector unplugged and at full throttle. Coolant temp sensor is reading proper resistance. Starting fluid kills the engine. Im at a loss right now
