this is the second time i drove the truck after the weather start to warm up and road salt was gone. took the truck on a scout backpacking trip 1.5 hours south of st. louis friday evening and came back saturday afternoon about 4pm. everything has been fine till this point. parked the truck on the driveway for about 2 hour taking a nap. Then fired it up to go to dinner. About 10 min into the drive (local, ~30 mph stop and go) it duddenly start losing power, runing rough. Pulled over to a parking lot. checked oil level, good. cann't see anything obvious under the hood and around the truck. It regain power and I drove her home (<10 min drive).

I did not drive the truck at all during the entire winter for concern of salt. Was thinking about pulling the 5ther to a state park for a few days during spring break. Thinking now, probably not until very sure about what was wrong. our big time travel season won't start until later in June. All the AE and Infinity and all the other experts (of course this includes Tugly) please help me find out what's wrong. Thx in advance. Eriwn

Tugly, can I send u the .csv file so u can help me clean it up and graph it? I did not learn that part yet. This is the 1st time I have to use the data logging to fix the truck. Thx

 

It has a fuel starvation sound to it. Do you have a fuel pressure gauge? How cold has it been? Is it still summer blend fuel in the tank? How much fuel is in the tank? How long since the last fuel filter change?

 

Fuel is a good suspect, and I don't remember if you did the UVCH work last year for the long road trip.

 

Thx Tug. Those r really good points. I'll look into it. Yes it's the feul from my 90gal tank filled before the winter last year. Yes as u probably knew, we had a very very cold long winter. No I don't have a feul pressure gauge. I think that this is a good time to get it. The tank is only 1/4 full. I need to check when my last feul filter Chang is. Yes i did the uvch last year. I'll send u the file in about 4 hours. Thx again. Erwin

 

Pikachu nailed it. I smell a Hutch mod in the vicinity.

 

Yes. I tried to deny it last year. Will have to do it before summer.

 

Am thinking about doing the hutch mod this weekend. For those tho has done it, is there enough time for me to get together all the parts and do it, lets say Friday or Saturday? Whats the place to go for parts? i know i can certainly find the answer by doing a 2 hour research. Hopefully someone can point me to the rite direction. Thx

 

I bought all the fittings at Home Depot, and the tubing at Auto Zone, or O'Reilly's (don't remember which). I think I had about 5 hours in it from start to finish, including lunch and a trip to the dealership to get a new pickup foot/screen thingy.

 

Thx. Pilachu. Is there a good write-up for that?

 

Welcome to guzzle's In-tank Hutch Mod Web Page

you can use just a 3007 from napa for the pre-filter

 

Yep.

Thx. I think that you guys just got me ready for the job.

 

I did the little plastic strainer for temporary (just make sure it's the diesel one), but I went in and made things permanent later.

 

I received the data, but I can't email from work... so I'm posting a short text here with the results:

Infinity has a feature where you can push a button (in the event of something happening) and it will immediately store the last few seconds of PID readings and continue on.

To clarify: Say your truck hiccupped at 12:48 and 37 seconds, so you push the button. Infinity then gets the sensor readings from before the hiccup and logs from that point on. This allows you to replay the hiccup in the data - extremely helpful.

Given the huge pile of data I received, I think EYYU had his Infinity set to log full time. It took me a while to find the hiccup in deluge of diesel data, but it was there.

The throttle went crazy (ICP/FIPW/IPR combination is real throttle), but nothing was happening... at least nothing more than just maintaining the same EBP, MAP, MPH, RPM, and all that other stuff that reacts to changes in throttle. This tells me the fuel was not there... unless somebody thinks of something I overlooked.

This is the first time I've seen data during fuel starvation, and I'm going to be using that in the future.

 

90 gallon tank? Is that a tank in the bed that feeds the main tank?
