Crank no start

Replaced fuel filter. Replaced fuel pump.
Took awhile to figure out if pump runs. It run for 2 seconds
on ignition. Pull coil cable out and checked for spark
using new plug. Shrewder valve shows pressure. Don’t
have gauge to measure. Do have check engine light on for
evapor emissions. The small hose got hole at fill tube.
It 5.4 V-8. It use to roughly idle at stop lights ones a week.
Then it got more often, ones I lost throttle, next day will
not start. Any idea what happened.
