I own a shop, and have had many years experience with stuff like this. Looking in my book for your vehicle it says " Throttle body injection" should be approximately 9-13 psi, "key on, not running", and the pressure should drop by 3-10 psi at idle. If you have the throttle body that has the poppet nozzles (CMFI) it will be different. This system looks just like a throttle body, but is different underneath the upper intake. If you have this system it should be 58-64 psi with key on, and fall off by 3-10 psi at idle.
Glad to help out, Good luck!!!

These trucks idle at about 11-15 psi. They bump up on acceleration to around 16-18 psi.

the electrical powered gas pump in the tank needs purely to have the cord connector hooked as much because it and turn the main to the commencing up place to have gas pump artwork. in case you have a helper turning the main to the commencing up and run place and not something happens, the two no potential to pump or the pump is undesirable.
