So I've been chasing a very low power issue these last few weeks. I ordered an isspro fuel pressure gauge and installed it the other day. I started the truck and it ran absolutely horrible and the fuel pressure started at 5 and went to 10psi at idle. Is that even possible?!
I dropped the tank figuring the pick up screens were completely clogged and they are absolutely fine. Very minor crud inside but nothing that would make the fuel pressure that low. I checked the fuel bowl filter and it is also relatively clean. Do you think it's my fuel pump that's toast? How do I test it to see if it's bad before just buying a new one and hoping.
