98 4X4 4.3L, HARD START OR NO START , STARTS WITH PRIMER FLUID, . STUMBLES AT FULL THROTTLE

1998 Chevrolet Blazer • 135,000 miles

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.

Check fuel pressure but let it sit for 5 minutes and see if it drops or not it sshouldn't drop over 10 psi but 62 psi is better
