Ford 7.3L Power Stroke (1999-2003) :: Blower Fan Intermittent / Resistor Pack Plug Partially Melted
Coming home from the shore and turned of the air but not blower. No speeds at all. Fiddled with it until I got to a rest stop. KOEO, tapping the blower did nothing and swapping relays did nothing. 40 amp fuse and inside #22 ok. Had some time last week and discovered that power to blower was intermittent. Pulled the resistor pack plug and it was partially melted and upon removal of resistor pack I could see it was toast. Replaced that and pigtail and still got intermittent blower and intermittent voltage at blower connector.
Days go by with only a chance of it working but noticed it turned on more when I started the truck with the blower motor switch turned on. Maybe bad contacts somewhere or maybe loose connector in harness I thought. I had been meaning to replace some burned out cluster bulbs with new LED's, so I bought a motor switch and did both items. Left the front dash part off because nothing changed as far as the blower was concerned.
I downloaded the schematic to end the frustration and see the power going into Mode Selector switch, black/yellow. My test probe gets nothing through insulation with KOEO. Pulling the connector and probing the contact of the blk wire and I get blower all speeds but no light glowing from test probe as if I just grounding it. I have to add that 1/2 the time I got not blower and 1/2 the time I did, so It was intermittent there as well. Doing this again several times while restarting the key to run and still the same until after about 8 times, I finally get a light on the probe, probing the wire while its connected and I get it now with it disconnected and all seems ok. I have blower each time for the last dozen restarts and I cant make any sense of it.
I just have a feeling this good heat isn't going to last. Should I replace the Mode Selector Switch? It seems the relay coil wasn't energizing but now it is. Last week I shot the relay seat with contact cleaner and replaced it with new napa one out of frustration.

So I just put billowed up pipes and changed the broken O ring in the turbo housing. Put everything back together and checked for a boost leak with the home made tester. Boots and everything ARE OK. I can hear air escaping from what seems to be the valve cover or intake. I realize that I am charging my crank case as well but it still concerns me that air is escaping from somewhere besides the CCV. I read the following forum and this guy had the same issue and after he found out he was charging his crank case he was no longer worried. . . . .

View 6 RepliesFord 7.3L Power Stroke (1999-2003) :: Leak From The Rear At Drain Valve
After checking my fuel bowl today for contaminants, I put the lid back on and then noticed a leak from the rear at drain valve. I know, I already ordered the orings. It was doing one drip about every three seconds with the truck running. However, I turned the yellow thing a couple times and the leak stopped. Not leaking right now. Maybe it wasn't shut from previous owner.
Second question.....After stopping leak and after routing my fuel drain hose, I decided to give it a try. No luck. Nothing out or drain. Based on my first fuel filter change, it may be clogged up. So, do I run wire from the bottom up? Or do I run wire from top (bowl) down? Just so you know, sucked the bowl dry with a vacuum device before I reinstalled the filter.

The bolt that holds the dipstick on the valve cover. i have tried for ever to get this thing off. soaked it , got a skinny wrench on the nut underneath but think it might be stripped (1/2 inch grinded out a little). going to try and get a set of skinny wrenches tomorrow , mine bent. tried vise grips on top of the bolt and put a box wrench on the nut , and gave it my all. The damn thing won't budge.
Also, any tips on the rest of the valve cover bolts. I had to remove some from inside the fender well but barely got to them. My question is not getting these out but getting them back in. And how the heck to you torque these things??? The bolt i mentioned above is creating problem, and I only have so much time

View 4 RepliesFord 7.3L Power Stroke (1999-2003) :: Started Up After Cranking A Couple Of Seconds / Blowing Oil Out - Valve Cover?
I had the engine out of my truck (7.3 with e4od) to do manifolds. Anyway, I got it back in and started it up. Since there was air in th fuel lines it had to crank a couple seconds but started up. I looked and now fluid coming out, then it sat for a few minutes running and I took it for a drive. While sitting in the driveway it wa smoking a bit. But I thought it's from the oil I got in the exhaust while drilling two of the manifold bolts and soaking the bolts with ATF/acetone. After about half a mile I thought that maybe it's more oil then that would cause... So I went back. I looked and the inside of the exhaust is covered with oil, and the rear of the engine is also.
When it was out I capped all of the open ports so I could pressure wash the grease off. Also, I flipped the CCV so I could do the delete. During instal, I missed the cap on the CCV and it was not able to breath. I think that maybe it built up pressure and blew the valve cover gasket? It looks like it's coming from the right cover on the backside; I had not taken this cover off while the engine was out. How much pressure does it build? Is it possible that it could have blown the gasket out? I have done the oil cap trick to test blowby and it always passed the test. What it could be? For the leak on the engine and why it's in the exhaust?
Ford 7.3L Power Stroke (1999-2003) :: 2001 F250 - Fuel Leak - Not Water Separator Valve O-Rings
I have a very small fuel leak in my 2001 F-250. I was going to just let it go until I needed to do other work (since I get 20mpg city and 25mpg highway), but I went to a "new" inspection guy, and he flunked me. So now I have to fix it. And for all I know, my mpg and fifteen other things will break when I try to fix this.
Today I spent 4 hours in the heat putting in two new o-rings on the water separator valve. But the truck still leaks fuel. Climbed up on top of motor while it was running and looked, but I don't see where the fuel is leaking out.
Online research suggests to me that the next most-likely culprit is a steel fuel line that wears through from vibration and chafing. Is that correct?
This truck is so eaten up with rust (came from salt belt) that I bought a LOT of fuel line stuff a year or so ago, so that when things started falling apart from rust, I would have the parts on hand.
Now I'm wondering whether I already have the part I'm likely to need.
So far, I have bought:
1. Dorman Fuel Supply and Return Lines
2. Riff Raff Diesel High Pressure Crossover (HPx)
3. Riff Raff Diesel Fuel Rail Crossover (FRx)
So my question is, am I likely to have something to replace the part that commonly leaks on these trucks due to vibration/wear/chafing ... or will I still need to buy another part?
I'm thinking that one of the two lines in item #1 above is the problem child...
Toyota - Camry :: 2000 - Driver Side Window Quits On Way Up / Partially Closing
2000 Camry XLE. Driver's el.window quits on way up, but will start again if I wait for one or more minutes before retrying. The longer I wait, the farther up it will go. Not fun at toll booths on rainy days. Started a few month ago when I forgot to close windows and the controls got rained on. Initially, a blast of WD40 seemed to cure the problem, but no longer. Took arm rest controls out, but couldn't see any obvious problems. Is this an aging motor problem? Do I have to get ripped off by dealership serv. dept., or can any reputable garage do it? I'm worried about taking the whole panel off myself. Don't have the tools to do so, and don't want to rip "leather."

Ford 6.7L Power Stroke Diesel :: Moon Roof Not Closing All The Way / Reverses And Opens Back Up
About a quarter inch before it gets all the way closed it reverses and opens back up. I can stop it with the switch anywhere in between while it is closing, but not while it is opening.
It is acting like the bounce-back feature (as described in the manual) is activating, but the bounce-back override feature (pull and hold the SLIDE switch within two seconds of a bounce-back event) does nothing.
There are no signs of restriction, as it opens and closes very smooth and quiet, but it did make a loud pop sound the last time I used it a couple month ago. I can count on one hand the number of times I've used it.
Ford 7.3L Power Stroke (1999-2003) :: Power Stroke Malfunction - In Reverse / With Lights On Engine Shut Off
Last November I forgot to plug my truck in and it got down to 0, my girlfriend tried unsuccessfully to jump start it. When I got home I jumped it and got it running. I took it down to a heated shop to troubleshoot the glow plug circuit. I discovered it was not getting 12v to the glow plug relay. Also I started it and tried to back it up in the shop, when put in reverse it killed the engine, not lugged it down it was like you shut the switch off.
Also I discovered if you turn the lights on it kills the engine immediately. It will not crank with the lights on either. So far I have replaced the computer,ignition switch,batteries, and cam positioning sensor. Now comes the weird part!! I decided to get it running and pull the bulbs out of the back up lights I pulled the drivers bulb first then the passengers side bulb. When I pulled the passengers side bulb it killed the engine.
It is not my daily driver so it still sits in my shop. I have a hunch it's a ground issue but I've checked and cleaned up all the grounds I can find and it still has the problem.
