The truck runs fine on the back tank, but when you switch to the front it stalls out. When you try to restart it does not sound like it was not getting any gas. I replaced the switch and now it sounds like it wants to start but will not. Is there a silenoid or valve that controls it and if so where is it located? Or is it a bad fuel pump and is there any way to test if the pump is bad.
Thanks in advanced for any ideas or sugestions.
