Assuming you 100% tested all those items, including: -Removing spark plug, ground to manifold, verify spark (rules out bad electrode, coil pack) -Testing injector signal with noid light, verify injector cycling via battery (if its partially running your timing should be close enough for all cylinders to fire) -Testing compression with all plugs removed, throttle open Cant assume any single thing. PTUs tend to fail warm, sometimes function cool. Wiring tends to vibrate loose.
