2002 Chevy Tahoe. The truck wants to start but goes dead?
Question edited for clarity.
Question moved to model category.
Did you disconnect the battery when you replaced the fuel pump?
Did you reset the security system and engine immobilizer?
Did you connect a pro grade scan tool and check for DTCs?
Not sure what you mean by 'cranks, then goes dead'?
It turns over than then next time you turn the key there is nothing, no noise, no clicks? Is the battery full charged?
