Ok guys here is what I have going on. My truck every once in awhile (usually after sitting a while) my truck won't start. I've had a fuel tester hooked up to it for a few days and when it won't start, I have 0 fuel pressure. I changed the fuel pump relay, it didn't help. New fuel filter as well. I usually just turn the key a few times and then I get 40 psi in fuel pressure, it starts and runs fine.
Why would I have this intermittent problem? The more I read and look into it I'm starting to think bad fuel pump??
