2008 5.4 refuses to start please help
Engine just died while driving home. Hit some washboard ruts kinda hard and it just died. Engine will crank over fine...just will not start.
Here is what I have done.
1) tried to start with starting fluid.....nothing
2) replaced crank sensor....nothing
3) got mad and had wife crank while I sprayed A LOT of starting fluid. After about a 1/4 can it fired up. Would not run very good....just barely idled, as i continue to spray starting fluid to it. pumping accelerator did not help, it just barely idled. It ran enough to pull 2 codes....both the same code P061B, and P061B with a small p and d next to it.
4) Replaced fuel pump....nothing
5) Replaced fuel pressure module...nothing
My research on P061B is something with transmission so I do not understand.
I see no test port for fuel pressure testing so I have not tested that, but now its a new fuel pump.....
Given the amount of starting fluid needed to start (almost 1 hole can, 1/4 can just to get it fired up and the rest of the can for about 2 min of running)....could the throttle body butterfly be stuck shut?
Please help I am at a loss!

It's definitely a fuel or air issue if starting fluid got it to run.. A new throttle body and TPS sensor might be the issue if your getting a transmission code. As you have already speculated, I would agree that its a good place to start...
If if cranks with no fuel smell following a long crank, then you may be spot on with the throttle body issue.
That, or there is a loose or bad connection with your fuel pump or FPDM... (This would explain how the ruts in the road caused the current condition.)
