I am new to this. My son was driving the blazer and it died on him. I changed out the fuel pump and still nothing I am not getting fuel. I checked the fuse and the relay. Could this be the cam positioning sen. or what please help

How have you determined that you are not getting fuel? Are you using a fuel pressure gauge? If so, what is the pressure with the key on, engine off? It should be 55-60psi and the pressure should not drop below 50psi for 10 minutes after the pumps shuts off.

 

The fuel pump does not run, checked and have power to it

 

The pump does not run when the key is turned on but i have power to the pump

 

If there is +12V power and ground to the fuel pump connector, the only other cause for a non-working pump is the pump itself.

 

thats what i thought and changed it and still nothing and i thought that it was bad so i replaced it for the second time and still nothing could it be the cam pos. sensor?

 

No, I do not think it is the cam position sensor.

As I already said... If you have +12V and a good ground to the pump, the pump should run provided the pump is good. Period, the end. You either do not have +12V, a good ground, or a good pump if the pump is not running.
