Fuel Pump Help

Hey guys my truck has had some issues starting and I took it to the mechanic and he said it had low fuel pressure. Basically when the fuel pump primes it doesn't sound like its "spooling" up or priming very strong. I bought a used pump off a guy on the org here, he claims that it only had 1000k miles on it and I put it in today. Well after I installed it the truck fires right up but it still doesnt sound like its priming very strong. I just dont want to spend money on this pump for it not to last and have to buy a new one anyway.

When I had my 03 the pump went and it was making the same slow "spooling noise" and I replaced it with a OEM pump and from the on it sounded and seemed like it "spooled up" alot faster and stronger. Any help would be great thanks!!

Hey guys, Just signed up and glad to be here.....well its kind of bitter sweet you know.
I was curious as to what noises, if any noises the truck was making while cranking. My truck is making a knocking noise while cranking and takes longer than normal to start but once started runs fine. I wonder if my issue is possibly a fuel pump related issue.

Check for fuel pressure at the engine filter housing. You'll have to peer under the intake horn, but you'll see a hex plug that you can remove, plug a line and gauge on there and turn the key "on" if you're over 40psi you're good, but 55psi is perfect.

And the HFCM pumps are quiet, I normally can't even hear them prime unless I listen for it.

Hope this helps

yeah I ve been driving it for a day or so now with the new pump. It starts up and runs perfect but it takes a while to finally fire, I have to crank it for about 10 seconds or so before it finally lights off. Any other suggestions, I probably wont be able to test the pressure until tuesday but thanks for the specs!!

This does sound like a typical fuel pressure issue - the extended crank, but as far as other culprits I'd lean on low HUEI pressure and/or FICM.

Does the oil temperature have any correlation with crank times?

well like I said in the previous post the truck had the original pump on it and its got 109k on it now, so I bought a nearly new one off a guy on here with 1000k miles and the sticker says its only 7 months old. With the old pump it would take forever to crank and spit and sputter to fire but it would start. With the new pump it just takes a little bit to fire but starts smoothly. HOPEFULLY its not the FICM!! anyway to test that?

Clys I was thinking about what you said earlier about the oil temp. and it takes about the same time to start every time I try and go somewhere. I counted and it takes about 7 seconds to start, I forgot to mention I am in sunny FL and the coldest temperature I have seen in 2 months in probably 45. Should I take it to the dealer and have them runs some tests or what is the cheapest way to go about this. I am pretty mechanically inclined. Thanks Again

I would purchase the HFCM by yourself and install. Quite easy to do provided you have the fuel line quick disconnects. Let me know if you need any help VIA pm and I'll be glad to help ya. Did you check fuel pressure?

I put the new pump on same scenario, just starts smoother. My roommate also has an 06 that runs perfect and I pulled his pump off as well and installed it in my truck just for curiosity and the same thing happened long crank before start. I had the fuel pressure checked on my old pump and it was low according to the mechanic, that's why I purchased the almost new pump off PS and it cured the rough start but not the long crank. THANKS A MILLION FOR YOUR INFO
