Hello, I am Randall. Can you re explain what you mean by:Fuel pressure only goes to 45 then back to 0 when you turn on the key and stays right at 60 when running.Are you saying when you just trun key to run in the am it goes to 45 then back to ) then when you get it running pressure holds at 60?
Yes that is correct. Before the engine is running, when you turn the key to the first stop, and engage the fuel pump, it goes to 45 psi then back to zero. But once it's running, it stays at 60 psi.(I guess it's psi)
Yes, its psi:) Have you ever had a chance to check the pressure once running, then shut down say 10 minutes and recheck the pressure?
have to check something. back shortly
Ok no worries....
I mean, I really don't mind replacing the FP if that's what I need to do. But an AC Delco pump is ~$350 and I don't want to spend the $$$ if I don't need to. I don't really trust the aftermarket brands like I do AC Delco.
Ok, my first thought would have been a fuel pressure regulator failing allowing fuel to return to tank slowly after sitting overnight etc. When you turn key to run in the AM, the pump has to fill the lines and then the air has to bleed and yes.. can shows pressures exactly like you have. However,, in the pump there is a plastic hose connecting ppum to top lid of the pump module. It is not uncommon for one of these to get a small hole in it and you will have the same bleed back of fuel from sitting. the clue here my be the stall when heavy braking sometimes. This in a way tend to point more to the pump module hose as suspected. If? you can check pressure after running ok, say within 10 -20 minutes of sitting, if pressure does not drop fast back to 0, then again I go back to pump module. I think pump working ok, but the connection hose may be bad. I hate to see you go to pump and its a regulator. the ONLY way to confirm regulator is we use a special tool to block off the return line from regulator to pump and try in the am. This 100% confirms but.. you do not have the tool so,, by the symptoms listed? I lean to pump module in the tank
I agree with the Delco parts but.. aftermarket have become much better so we do use them with little trouble as well./ hate to say this but is you want to do the regulator, if problem persists, its the pump module
So are you saying the connection hose or the entire pump?
Or can that connection hose even BE replaced?
Or maybe not worth the trouble maybe....
I have yet to find the hose as seperate part unless you rig a type of rubber hose. After all the work to drop tank? dont do this. I think I can send a picture.
see the coiled hose in the middle
Naaa.... if those hoses aren't normally something that goes bad and available.... don't worry about it I won't go that route.
I agree, dont take shortcuts, was just giving options we have used
So it's your recommendation that I go with a Fuel Pressure regulator first and see if that solvs the problem.... and if it doesn't, then a full blown FP assembly?
Its near 100% one or the other.. Let me see if i can send regulator information to you. Back shortly
ok, somehow I lost your reply. The last one I saw was the picture of the fuel pressure regulator. Everything keeps opening in a new window and they all say "loading data" LOL
Ok, well I'll go ahead and do the FP regulator first. Even if that's not it, the existing one is 13 years old and would need to be replaced soon enough LOL.
let me switch out of chat. it acts up sometimes. back in a second
ok maybe this will work....
I haven't seen any BWD pumps, but I'll look. Knowing me though.... I'll end up with the AC Delco pump if that's what I need.
THANK YOU Tracer. I will GLADLY accept your VERY informative answers. I really do appreciate you taking the time to chat with me this evening.
