Low fuel pressure

05f250harley · Oct 27, 2015

I have a 2012 f350. It comes up low fuel pressure on the dash. It's throwing codes p0093 and p008a. It runs fine after I clear the codes but doesn't take long before it pops back up. Sometimes it'll shutdown. Any ideas of what the problem is? I had the fuel filters changed 2000 miles ago and just changed them again.

How many miles are on the truck?

It has 138k miles on it.

Are you getting any codes? Although rare, you could have a low pressure pump going out.

P0093 and p008a

I was thinking maybe a sensor or something like that because it will run fine after I clear the codes until it throws the code again which doesn't take long. It does seem to be worse when putting more load on the engine.

Sorry, I saw that you mentioned the codes in the original post. The P0093 code is a large fuel leak code. The P008A is a low fuel pressure code if I remember correctly. I'm assuming you don't have any leaks so I would have to guess that you may have a bad sensor.

Are there alot of sensors to check. I have a 2011 that I can borrow stuff from to check and see of that's the problem. Maybe the fuel pressure switch?

So I took it to a shop and they told me they think it's the low pressure fuel pump. He wants $740 parts and labor. The ford dealership up the road want $350 for the pump. How hard is it to change the pump?
