I just replaced my fuel pump on my 97 jimmy. I bought an Airtel pump with the new harness. My fuse and relay are good? Pump isn't turning on. Any thoughts?
well frist off you need to know if the relay is working (clicks when you turn the key on) If so then you need to check for power to the pump. Also you need to check your ground wire for the pump.
Let me know what you have (power and ground wise to the pump)
