I recently bought a fuel pressure test at an auto parts store and when I hooked it up I was only getting about 17 psi when idle. Did a long term fuel pressure drop as well, but the pressure remains for a good 8-10 hours but does drop overnight. Another odd thing is when key is set to on but not starting, the pressure barely climbs any psi (only about 1-2 psi). Starting to think that the fuel pump is going bad, also I bought a new fuel filter because it’s about time to replace it as well. Just want to know any suggestions on this matter. This was a solution I was looking into for my truck hesitating while starting. What I mean by hesitation is the truck will start, but sometimes it will take 4-8 seconds.
have the same problem?
