Have you replaced the fuel filter and clean the throttle body?

40

I replaced the fuel filter I have not clean the throttle body although I have been putting injection cleaner and I need some seafoam to clean the intake

I meant I did put some seafoam in it and it seemed to help I'm just not sure why it keeps stalling I'm thinking maybe it might be the manifold absolute pressure sensor

If truck start,s right back up,you may just need a good cleaning at the throttle body.

Is engine light on by chance?

It's interesting that you asked that because ever since I replaced the fuel pump the security light check engine light and low fuel light flash and I believe that's it's the fuel sending because my gas gauge doesn't work now either I believe it's wired wrong would that affect the operation of motor?

Is there a particular product you would recommend for cleaning the throttle body?

The fuel sending unit would not affect the running of the truck,and if engine light is on it may not even be the throttle body that need,s cleaning,think you may find it to be a throttle position sensor or air control module issue,go have it scanned at your local auto part,s to no which one you may need.

well that is another issue in itself because I have a scanner but it will not connect to my computer nobody's scanner will connect to my computer I don't know I don't understand it
