The tank selector valve fixed the problem I've put almost 200 miles on the truck in a day, and WOW it is a great truck. Thank you all for you help and info.
I tried to get the pics loaded but it says too large.....
Finally, I located a F250, 173k miles, 1997 powerstroke, seven houses down my street. It was not for sale but hadnt moved in over a year. I asked the owner, a plumber, what was the deal. He said he bought it from a fellow plumber almost 1 1/2 yrs earlies. After purchase he drove 90 miles to a job site, it quit on him. Had it towed to a mechanic, result= No problem found. Next day same trip, quit on him again. Well now a year later, and reading this form I figured it was a Cam sensor. So after a few beers, I convienced him to sell the non running truck. I changed the starter, batteries, fuel filter and cam sensor. It runs..SWEET. Im dancing in the rain! That night I drive it at least 10 miles all over town. Next morning, I'm thinkin what the hell, lets drive it to work, 30 miles. Well at 65 mpg and 10 miles in, FUEL FILTER light comes on and truck quits on freeway. Ten minutes later, fires right up and runs for 5 miles. afterwards no go. A diesel mechanic I know said drain fuel bowl and add tranny fluid....It runs!! dancing again. 10 miles later and 70mpg...quits on me again (this time NO dash light). I tow it to that mechanic friend's were it sits for a day. Today he tells me it fires right up and drives ALL OVER TOWN. NO PROBLEMS. He even let it idle for two hours, no misses or anything. says it purrs and runs darn good. WHAT!?!???
So here is what I know: supposidly, the computer was replaced at some point, both tanks were already full at purchase so I added diesel additive, the fuel gauge is way past full and doesnt move when i switch tanks.
My mechanic (diesel) think possibly that tank switch would be malfunctioning causing a problem in backflow and pressure. Tomorrow he will run the truck on a lift to recreate the problem
Another friend says he thinks a bad catalytic could cause this.
PLEASE HELP ME! I have been searching for a powerstroke and am super anxious to get this one on the road.
If you need any further info please ask and I will respond a.s.a.p
So today I spent my day off the shop where my truck is located. Remember the mechanic is doing this as a favor. So he mentioned he has witnessed no problem. Small test ride with me following, no problems. I take off again heading for the highway and the fuel filter light comes on. I head back to shop and he drains the fuel in bowl. Definately water in fuel. Then find that drain valve wont drain. He uses an airhose and covers the bowl with a white terry cloth.....MUD come up...LOTS OF MUD. So he cleans it thoroughly and adds ATF and it running again. Moment later down the road, filter light again. I open valve and let a little fuel out...light goes off but moments later the truck stops. 15 minutes later it starts and I get back to the shop. it eventually idles to it shuts off. The open the bowl and its LESS THAN HALF FULL and only has the ATF in there. So minutes later they fire it back up and by then Im frustrated and I left, 6 pm. So I believe everyone is right in that the tank has crud in it however I still need to figure why that bowl isnt full, if it should be.
Let me know what you think....Thanks
10/30/09 UPDATE !!
So today, I removed the FPR and cleaned the caked up screen near right 10mm bolt. I thoroughly cleaned it out and the metal mesh a the bottom of the unit.
So then, I did a pressure test during idle and 2k rpm. Note that I did fill the fuel bowl completely with tranny fluid first.
The initial reading at idle built up to 30-35 psi. I relieved the pressure and started again. Slowly it built back up
Once I went to 2k rpm, I dropped like a rock to 0. It stayed at zero until it went to idle. At idle, it slowly build back to just above 30.
Earlier in the day, we pressure tested the left port of the lift pump and it was about 6 psi (at idle)
Question: Does any of this sound normal operation, or normal of a failing lift pump.
I would like to move forward tomorrow (saturday) with your help and start enjoying the stroke.
if you need more info please dont hesitate to ask.
Thanks to everyone!!!
Problem fixed. NOT THE FUEL PUMP!!!
I spent today replacing the fuel pump. While there, I removed the fuel canister, blew all lines, replaced all hoses. After reinstallation and a new fuel pump, problem persisted. Idle fuel psi, just shy of 40 psi. At 2k rpm 0 psi. What ??!!?? So we looked at the next item in the fuel system...the fuel selector valve. I removed the feed line to the engine and placed it in a 2 1/2 gal container of diesel. IMMEDIATELY, upon idle, it shot to 40 + psi. At 2k rpm...70 psi. PROBLEM SOLVED!!!.. Unfortunately it is 5 pm and Saturday... so first thing monday I'll be at the ford stealership.!!
Thanks everyone, and when I'm done I"ll get those pics loaded.
Next questions will involve the HPOP and general maintaince of the Stroke!
