i installed a fuel pump about a week ago. and i read my codes today and i got P1105 wchich is the fuel pressure solenoid. so i was wondering if changing fuel pumps could cause this or is my fuel pressure solenoid bad. thanks Robert

Was it a replacement, or an upgrade like a Walbro?

I never heard of installing a 255lph Wally and getting a CEL code for the FPR. But anything can happen. If you really did up your pump to a 255, get an AFPR as well.

Yea, I would have to agree, but that is the only thing that seems like would cause that issue right after, unless someone else has another idea.

Yea it is a wally but its only a 190. but there is nothing else i can think of besides my fpr going bad.
