No that isn't correct. If you turn the key on engine off it should go up to around 60 and not drop more than approximately 5 PSI in 5 minutes. This is just a rule of thumb so if it drops a little more I wouldn't worry, but down to zero isn't right. Is this when trying to start it or just with the key on. It could be bad regulator, pressure valve in the pump, or leaky injectors.

That'd be a heck of a leak if the injectors weren't holding pressure ...
Definitely isn't supposed to be doing that. |
It drops to zero just when the key is on. If I try to start it the pressure jumps back up to 60. I can't seem to find the fuel pressure regulator. Does anyone know where it is located? It is not by the fuel rails at all and I do not see it anywhere else.

It should be on the drivers side of the intake on the fuel rail...

yea I wish it was but it isnt
|
Any other ideas as to where it might be? I searched and searched but still cant find it. Is it possible that this truck just doesn't have one and if it doesn't then how is the fuel pressure regulated? Oh man this is really getting ridiculous but I will get it sooner or later. I really appreciate the help on this matter.

Well I guess you learn something everyday...

Thank you Mr_Shamrock that definitely explains why I couldn't find the regulator. after looking into the fuel pump further i found it is located there but now I am still stumped because I don't know why it wont start. So if you come up with any more thoughts please share them with me. Thank you

lol there is a check valve in the pump also . dose it hold 50 psi running ? give or take
|
if it only has one fuel line the reg is part of fuel pump ass.
