trucks acting up.

I have a 2000 F150 with 4.6 in it, lately after it sits for a while, it has to crank over several times before it starts, it usually fires in a couple of revolutions. This leads me to believe that the fuel pressure is bleeding back, am i right? And what would be causing this?

[2 beer]

try to turn the key to run but dont start it. Do that twice before you start it and see if it fires up. If it does thats a good sign its bleeding off pressure

Does it only do this when it is cold out? I have the same problem in my blazer, just let it sit in the run position for a few seconds before engaging the starter.

Takes longer for fuel to atomize in the cool temps.

Or, what Cory said.

Go to Autozone and have them run the codes

hmmmm, I had that happen. I had to replace my pump. I thought for sure it was the regulator, but thanks to the internitz, people told me it t'was the pump.

They exact same thing happened to my mom's jeep, we replaced the fuel pump and sending unit and it took care of the problem.

well they say your not supposed to run the gauge down to empty, i have heard that from a couple different people now, they say it sucks debris in the pump and wrecks it. And i do run mine down to empty.

I have heard that too and weather it is true or not I still try not to do it. Besides the shit in the tank, the fuel cools the pump, so when low on fuel the pump probably isnt cooling as well cause it isnt submerged anymore

I never run my blazer below a 1/4 tank because they are known for fuel pump problems anyway.

See if Walbro makes a pump for your truck, because I put a NAPA pump in, and it died a mile down the road, so I went to Ford and bought an OEM one with all of the shit attached. Cost me almost 300 bucks. I look at it, and it's a fucking Walbro. Way to mark up the pumps by a fuckload Ford you asshats.

[SVT5LITER]

Walbro makes GM pumps as well... and Holly pumps. Shit.. I have a GM Universal Holly 255lph... and it's the same damn pump I put in the Cobra.

Get that fuel filter swapped out either way... and hope it's just the regulator and not the pump.

[01darkblueTA]

after it runs pull the vaccum hose off the regulator to see if fuel comes out of it. that happened to me in my 96 beretta last year around this time when it got cold. replaced the pressure regulator and it was fine.

[RyanM]

for the ford it needs a pump and tim the blazer needs a regulator

[clint]

I would sell the blazer, we had one and it was rubbish, as well as two other people i know, whos blazers were not quality.
