ranger cranks a long time before starting

2001 ranger 4.0 sohc motor cranks a looong time before it starts and then runs fine no issues.

i KNOW what it needs but i need to know if i can buy it and where it is..

the fuel pressure doesnt hold it drops off right after the truck is turned off so therefore it need to build pressure before it is started. where is the check valve that is supposed to hold the fuel pressure?? i replaced the filter thinking it was in there cause the filter looks like it rgulates pressure but it didnt fix it.

so is the check valve sperate from the fuel pump or only an assembly??

well its a friend of mine but yes it does.. crank crank crank crank sputter puttt putt putt sputter putt.... vrrooooom all smooth and great. only time it shows any sign of being messed up is after it sits for an hour or so. i found that the fuel pressure drops off quickly after you turn it off.. but i dunno where the check valve is that is supposed to hold the pressure.. although i assume its in the pump

I've been procrastinating (sp?) on swapping my fuel filter out. My truck has 164K and lord knows how long ago what filter was changed. I have noticed though it doesn't do it near as bad when I run a high octane fuel in it. I think I have some sedament thats blocking my filter.

One suggestion I'll make, and this is how I get mine to crank without burning up my starter... turn the key to the on position (don't try to start it), wait til the 4th ding, then shut it off, try it a second time, turn the key 4th ding, then turn it off...let it sit for about 3 seconds, then fire it up.

What that does, at least in my case, is primes the pump and puts enough pressure through the system to knock down any blockage in the system. Mine came from a bad batch of gas from a shady station I filled up at over a month ago.

Well I know it was changed at the dealer it was traded in at at 106K, but I have no idea if the guy I bought it from ever changed it.

It's frustrating when you sit and crank on the truck for a while to get it to start... I always think someone's staring at me when I try and get it started.

I at first thought there may be something wrong w/ my fuel system too.

What you are doing is very similar to what I used to do. I would turn the ignition to run 3 times w/ a 3 second pause in between. The 4th turn would be to start and viola! Every now and then the engine would stumble but then smooth out and run fine.

After reaching my destination, it seed as though the length of time my truck sat would determine if it would start w/out going through what I said above.

There is nothing like having the chick you're flirting w/, a bunch of directors, the president and the owner of the company I used to work for standing next to my truck while I tried to start it on many many occasions.

That said, who's checked their battery and connections lately? Yep, it was that simple on mine.

Come to think of it, I do have a little corrosion buildup on my neg. cable.

Guess it's time I stop procrasinating and throw my redtop in and check that connection.

As you said the check valve is bad and you need to replace the fuel pump to get a new check valve. A clogged fuel filter will not cause those symptoms. There are some other things that could cause a drop in fuel pressure after you shut off the key but it is most likely the check valve.

My old 2000 did that all the time, wouldnt want to start, then with more cranking it would, and it'd fire up and be fine. CHECK YOUR PLUGS! That's ALL it was on mine. Turned out those plugs had 170k on original plugs and wires. I did plugs, wires, and the battery and it'd fire over AS SOON as you turned the key.. almost instantaneously.

BTW I didnt read the thread to check and make sure you did plugs or not

EDIT: Ok.. I re-read. Check your damn spark plugs everyone. Run a can of seafoam through the truck (through the brake booster hose), and also put some in the oil... Give it the half an hour to let the seafoam soak and do its thing. Fire the truck up and take it for a "spirited" drive for half an hour or so. Give it 6k RPM's as well. Then when you get back, check (and preferably change) your spark plugs and oil. I did this and the truck fired right up perfectly EVERY TIME from there on out. It was spark plugs for me, and I had all those symtoms.

The check valve is in the fuel pump? I mean where else could it or should it be? I know for a fact there is nothing from the pump to the filter. and from the filter to the fuel rail there is one item in the drivers side fender well. but i dont think that is it.

Last truck I knew to have similar issues like this, (was a ranger) it was a bad fuel pump. But on an 06? idk seems very odd.

Can you check the line pressure while its running? maybe its dropping off then to.

The fuel pump isnt bad to replace once you get the bed off.

if you run your truck on a 1/4 tank of fuel or less alot then it will wear the pump out quicker. The pump needs the fuel to keep it running cool. (from what i understand)

Hi, Got the same problem. When i go to start the truck after its been sitting for an hour or so it just cranks and cranks and cranks. after it starts it runs fine. I took out one spark plug, look like the engine has been running hot. just did sea foam on the intake. any help would be apreciated. 2002 ford ranger 58689 miles 3.0L V6

You know, I've been having this problem recently too, and my new optima yellowtop seems to have fixed it.
