Well, I got the selector valve installed properly and added the filters and its still doing the same thing When its in the lower gears and I push the gas it has no power and almost dies, it just bogs out. Then when I parked, it just about died. When I get to the higher gears (if I can get it going that fast) it seems to run ok, but still not right. I know its not the pumps in the tanks because it does the same thing on both tanks, and I highly doubt they went out at the same time. I can hear them come on when I turn the key too. My only other thought is that it is my high pressure pump between the reservoir and the engine. Is this a possibility? Please help! I'm becoming very frustrated trying to get this figured out and having to borrow peoples cars to get around. And does anyone know how I can check my pressure from that pump before I go buy it and find out that its not the problem. Thank you guys

 

did you happen to think about bleeding the air out of the fuel lines when you put the filters in the truck?

 

Ummmm, no. Would that be causing it? And wouldnt that go away after driving a bit? I drove it about 10 miles since I changed the valve and added the filters. But it seems like its doing the exact same thing as it was before I even changed that stuff. On another forum someone is saying it could be my high pressure pump, or my catalytic converter.

 

I would suggest that you invest in a fuel pressure gauge before considering any more additional expense. Once you know if you have the correct pressure available , or not, then you can decide to spend what you need to spend in order to correct the fuel problem, if it is a fuel problem. Just to keep throwing parts at it gets expensive and frustrating if you don't replace the defective part, again if there is a defective part.
Earlier you stated after you replaced the valve it ran fine and now it won't run good at all. This would lead me to believe you may have more than one problem.

 

Well, when I said it ran fine, I barely drove it. I just went around the block. The last time I drove it, I went farther and it was fine in the beginning but then started doing the same thing as before I started fixing anything. Im trying to find my schreader valve to check the pressure but I cant find it. I know its on the fuel rail but I'm not seeing it. On another post someone is saying I'm only looking at half of my fuel rail and its on the other half, but I don't know where the other half of it is. Here's a couple pics of my rail if anyone can help me locate the schreader valve. And the tank selector valve that I replaced had to be replaced anyways because it was leaking pretty bad, so I haven't wasted any money so far, thankfully.....
