**I'm 10 hours from home. Help me diagnose this!!!**

[PwtrSS_OakCliff]

Guys. I'm visiting my sick uncle in El Paso, TX, from Dallas,TX. It was about peak of 80 degrees outside. I Was driving around for about an hour and I went to pick up my aunt from work. I waited a little over 30 mins waiting for her. I was idling for that time and had the AC on. I went to drive to the highway ( 5 miles) and I turned and press the accelerator about 85% (20mph) to the floor as there was an 18 wheeler close. It hesitated and the motor acted like it was going to turn off and it did. I pulled over and turned the key and it wouldn't start. It turned for a second or two and it died. It seemed like if it needed gas but I have 3/4 tank. I kept trying and trying. After 5 minutes it turned on. It was driving fine under normal driving conditions with no AC on. I they attempted to do a WOT and the motor and transmission engaged but it didn't really put me back on my seat like it always does. I went faster but not like it always has. Once I got to Autozone it turned on and off like if nothing happened. Just the WOT deal. I went to my uncles house and let it cool down. I took a spark plug out but no wears of oil or gas. This truck is always at normal temperature conditions at all times (205 degrees I think). I took a drive a little ago and it put you back in your seat and sounds healthy. Can anyone please share any experiences like this or let me know what I need to check for or possibilities. I really need your guys help. I'm leaving tomorrow and don't want to be stuck in the road.

Thanks.

Antonio

That's a long time

That's a long time

So not good to leave on for that long. I doubt a 2013 Yukon would have the same problem. Why NBS?

As long as the engine temp was fine I dont see how sitting can be what caused this. I am not saying I am right, but I do not feel the two are correlated. Hopefully someone can chime in to help with more information.

 

[slipping]

kinda sounds like what happened with my wifes 04 hoe, but she run the tank DRY like a stoopid. It runs fine, but has some hesitation at startup on occasion .How is your volts? hers will drop to like 9, when it occurs, putting it into reverse. Sorry I dont have more info.

And my wife does leave hers running for long periods of time as well.

 

[PwtrSS_OakCliff]

Volts are over half. And tank always has at least 1/4 tank.

Oh crap your in my hood lol...

Check plugs. Sounds like maybe dirty fuel or fouled plugs. You can try leaving it in park and going WOT to see if it will burn the gunk off your plugs. Assuming it could be bad plugs.

I already Checked plugs and they all look fine. I have an almost new alternator. Charges good. Don't think that's a problem.

I'm in Downtown El Paso.

Well if you need help let me know. I'm in the northeast.

Thanks bro. I appreciate it.

I wouldn't be too concerned that the idling caused it. I'm up in Massachusetts and during the winter, I DAILY left the hoe running for a good 20 minutes in the morning to warm it up before I left for work. Nothing like you're describing has ever happened to me. I wonder if maybe you just tricked your computer with your throttle inputs during the semi truck scenario and it dumped a bunch of fuel into the engine in anticipation of needing it and you simply flooded it. May have fowled some plugs temporarily.

 

[PwtrSS_OakCliff]

That's seems logical and a good reason why it would happened. Thanks for your input dropmech.

Sounds like the crap my OBS was pulling when the MAF was intermittently going wacky....

(This is by no means a diagnosis, just very similar symptoms)

I'm leaning toward fuel pump, check pressure to verify

 

[Mr.Jack]

Probably fuel pump.

 

[Big Buttons]

You ever get home bro?

 

[PwtrSS_OakCliff]

I got home a while ago. The motor turned off 3 times when I had increase acceleration when going up hills and the motor would stop and shut off. I tried to turn it a couple times till about the 10 time it will turn on. WOT is a joke now as it hesitates. I have not change the fuel filter since I bought it Oct 2011. So I'm trying to figure it out but now I see it has a Ford Fuel filter of that makes any sense. The first pic is the one from autozone. The second is what's on there. I do not know how to take it out. Special tool?? I'm hoping it's the filter and not the pump.

[bkboatnsleds]

fuel filter and fuel pump.. I'd personally start there.

Do the same issues occur if you leave it in park or neutral and go WOT? If they do then do a fuel pressure test and see if the pressures drop. If it only happens under a real load then most kits have hoses long enough to run them out the hood and up against the window. Go WOT and see i the pressure drops. Not the safest method but it works and will verify fuel pressure is the cause.
