Initially truck would run for 8 minutes then shut off, replaced fuel filter. Now it only cranks over but not start. New rotor, cap, spark plugs +wires, fuel pump, coil, fuel filter, ECM. Also replace pick up coil and distributor

Hello,

Is your check engine light on? If so need to get codes pulled.

Here are a couple possibilities on problem.

Detonation "Knock" Sensor

Throttle Possition Sensor (TPS)

or

Manifold Absolute Pressure (MAP) Sensor
