Fuel delivery issue?

Got a few of those now. Both sensors should be here tomorrow.

I'm curious what your cam bucket looked like at the mileage you're at? Got any pics?

I saved it. I’ll post some pics when I get home from work.

2014-2018 Fiesta ST FORD OEM Cam Bucket at 110k miles. I was expecting to see more wear on the cam side, but evidence points to more wear on the fuel pump side. Note the concave wear.

So, the replacement of the fuel pressure sensors fixed the fuel issue. Not positive which one because I replaced both low and high pressure at the same time.

Immediately, thereafter, the “Help! Low boost - new sound” thread issue occurred.

Keeping me on my toes!

Do you have part numbers and locations for these things? I'm pretty sure I'm having a similar issue. Lowside fp actual pressure at idle is 102psi and I think it should be like 70-80.

Ill have to re marry my AP and see if this is whats causing my bucking while accelerating on the freeway issue i was chasing last summer. ( itll more than likely come back this summer too) no codes yet for me. Im at 104k. Roughly where are these sensors located in case i have to replace them. ( should also do the cam follower...)
