Truck starts hard once it’s been sitting for an hour or more. It will fire right back up if it’s on sat for 10 minutes. I tested the fuel pressure and when putting the key into the on position, it only went up to about 20 psi. Turned the key off then back on and it went up to about 45lbs. Third try and it makes it to 60-65 psi. After seeing this I replaced both the fuel filter and fuel pump with no change in starting.
After some research and frustration, I’ve moved on to thinking the fuel pressure damper may be bad. The biggest reason I suspect this is that I have a vacuum leak I’ve been dealing with inside the dash and it smells of raw fuel. Apparently if the damper goes bad it can/will allow fuel vapors into the vacuum lines and of course you’d smell it in a vacuum leak.
What I’m unsure of is if the damper would cause these starting and fuel pressure issues as well. My 2nd question is where the heck is it located? I know what it looks like, I would imagine it’s on the fuel rail but I just can see it. Would I need to remove the intake and maybe the fuel rail to get to it?
Thank you for any help you can provide.
