No start or hard to start, will start after spraying fluid into the intake but stumbles at full throttle. I changed the E.C.M. And fuel filter. I checked fuel pressure. It was 60 lbs. The fuel filter was 85% restricted. Still have no start after sitting a few minutes or hard starting while spraying fue into the intake.
