Any help would be great....

I have a 2008 F150 xl with 110,000 miles

Recently it has been running rough and has stalled on the road.

The Check engine light is on....

The error codes have come up as follows:

4 x P0191
1 x P0316
1 x P1233

I was advised
to change the Fuel Rail Pressure Sensor, the Crankshaft Position Sensor and the Fuel Pump Driver Module

I have found information on how to change the FPDM, seems straight forward enough, but I cannot find CLEAR information on WHERE and HOW to should change the Fuel Rail Sensor...

Can anyone tell me exactly where its located and any tips on changing it?
Also for the Crankshaft Position Sensor.

Thank you in Advance

It is on the top driver side of the fuel rail, there is a disconnect wire plug in one end and a rubber hose connected to it also

I had the same problem with he fuel rail pressure sensor and i ended up having to get a new PCM because of it. Hopefully you just need a new sensor !

Before doing anything with the fuel rail pressure sensor, check and replace your FPDM. Save yourself a lot of heartburn, if you're getting oddball codes it's a good starting point on these truck, especially if you're stalling out while driving.

Do what he recommended bro.. FPDM first, drive and see what other codes pop up... sometimes 1 thing causes the other codes to "pop-up" b/c its the root of all the rawkus!

Let us know what happens, curious!... Good Luck

My pressure sensor had an o ring go bad on the inside causing it to leak fuel. And of course you can't just by the o ring
