99 silverado w/6.0 L engine starts and runs 3 seconds then shuts down. replaced fuel pump and tried to run with help of carb cleaner with no change in situation. Has no codes stored. Will start right back up but still only runs 3 seconds.

Power the coil direct from the battery if continues to run-check and test the primary ignition wire/resistor back to the ignition switch
