Truck will start and run for approximately 10-15 seconds then dies.
replaced fuel pump, fuel filter, fuel lines, fuel pump relay, ignition module, cap. Rotor, ecc. (Engine control computer) and battery! Still starts and still dies after 10-15 seconds of running

When it dies, double check fuel pressure and also look for spark-if okay check the EGR and PCV valves

Today replaced throttle positioning sensor! Still running and then stalling after 10-15 sec. Check engine light does work and has never come on or sent a code!

Will it stumble, like its running out of gas, or just shut off? If it stumbles, try spraying some carb clean into it, see if it stays running. This will verify if its fuel, or spark.
