Fuel pressure issue

[strokin629]

I'm having a fuel pressure issue and need some help before I go buy a new fuel pump. The truck is an 06 with innovative tunes and the blue spring update. most of the time it idols at around 62 psi and when I drive around its between 40-50 psi and when I put my foot to the floor it goes down to as low as 10 psi and then occasionally il start the truck and she'll never get over 45 psi. Do I need to bite the bullet and replace my fuel pump?

what tune are you running.. have you tried returning to stock? how do the fuel filters look?

The fuel filters are about 2 weeks old, and it does it on stock tune also

Check Ebay for the fuel pump, a lot of times they can be had for a little cheaper than straight retail

PFB-101 is the newest motorcraft number. 6C3Z-9G282-C is the ford number

Have you drained your HFCM lately? Do you have a blue spring kit installed? I just went through the same thing as you. Changed my filters and drained my HFCM regularly. Each time I changed my filters there was always a little debris in the housing, so I just cleaned it out. Nothing but diesel came out when I opened the drain. Then I started having issues with psi, so I decided to pull the pump apart.

^^^ this was packed behind the front cover and it was solid and hard. I dug it out and pulled the pump itself which was discolored from starvation. Long story short put it back together after cleaning and the pump wouldn't prime to save it's life. It chit the bed right in my driveway. So.... that being said, check the filters, spring, etc first. And if that doesn't do it check the pump.

Yeah, but not everyone makes french fries in their truck!

You more than likely have to replace the pump, and yes, it may be a good idea to take it off and crack it open. However, you could just change the pump in the truck.
