Was acting like a clogged fuel filter or bad fuel pump, lagging at stop lights clearing out when giving it a lot of acceleration. Truck finally quit running I replaced fuel filter and pump cranks but does not start over. I checked fuses and replaced fuel pump relay still no start. Any thoughts or ideas? Thank you
