View 1 RepliesFord - E150 :: Check Engine Light Keeps Coming On - Vacuum Leak / Fuel Pump
I recently had a Jasper rebuilt engine installed in my Ford E150. Since than my check engine light keeps coming on and the computer is saying my cas air mix is "lean". The instaler says i need a new fuel pump.Another mechanic says it is more likely a vacuum problem.I know it's possible that the fuel pump is bad bur since this has just started since the install, I don't believe it can be the fuel pump unless it's just one hell of a coincidence.
View 6 RepliesFord - Ranger :: 1997 - Vacuum Lines Coming Close To Hitting Serpentine Belt On The Front Of Engine
Ok, I have 1997 Ford Ranger, 4cyl, manual transmission, and more miles than I'd like to admit to.
Yesterday, I noticed that one of the vacuum lines was coming dangerously close to hitting the serpentine belt on the front of the engine. The clamp that normally holds the vacuum line in place rusted away a decade ago, so I decided to use some velcro ties to attach the line to the positive battery cable. I didn't twist or pull on the cable in any way and the vacuum line isn't applying any force to the cable.
I get in the truck a few hours later, hit the key and I get >click<, but nothing out of the starter. One click when the key is in the start position, nothing more (as opposed to click-click-click).
Not thinking about my repair earlier, I went down to Autozone and had them test the battery - 12.8V and 550CCA, no problem there.
So then, I thought well since the click is coming from the starter relay, maybe that's where the problem is. I read on another forum that sometimes the starter relay can be resurrected temporarily by hitting it with a hammer. Which I did. And it did work! Now the truck is starting up normally every time, but I'd like to replace whatever was bad.
My questions :
1. Did I prove anything by hitting the starter relay with a hammer and then starting the truck?
2. Should I still be looking at the battery cables?
3. Should I stop hitting random parts with a hammer and take this truck down to a real mechanic before I do serious damage?
Ford 6.7L Power Stroke Diesel :: Brake Vacuum Pump Oil Leak?
Haven't found any other useful info on this, but local dealer says that's where my truck is leaking oil from, and since it's considered brakes not powertrain the repair won't be covered under warranty ...
Backstory goes : dropped my truck off at local dealer Thursday to repair an oil leak from near front main seal area of the engine discovered while inspecting to initiate a bumper-to-bumper warranty through Ford ESP- their platinum warranty. I figured with all the electronic widgets and non-powertrain stuffs on this beast I wouldn't mind paying for 3yrs/36k miles of trouble-free motoring, y'know?
Apparently it's the O-ring on the brake vacuum pump that's allowing engine oil to leak. I can't even find this thing, just looking for some further explanation. I'm keeping an open mind so far, I don't suspect the dealer's just trying to get one over on me, just trying to be good and educated before I go plunk down for the repair.
Ford Excursion :: Stuck On Defrost Vacuum Leak
Ok, I have capped off the vacuum lines to the front hubs and replaced the vacuum solenoid on the passenger inner fender. Still stuck on defrost. I know there are several options from this point what would be the next step after what I have just recently done. Going away on a ski trip and would like to have it working properly before I go.
View 14 RepliesFord Excursion :: Sound And Vibration While Driving Forward - Possible Vacuum Leak
I have been having some issues I think are vacuum related but I'm not sure how to correctly diagnose or pinpoint exactly where the problem is. 2 issues that seem vacuum related:
The first is a sound and vibration I get while driving forward. While the wheels are moving, it sounds just like a baseball card in bike spokes, it usually happens after I backed out of a parking spot and put it back into drive. I will get that sound and vibration until I slow down, and just as I begin to stop, I feel and hear a big bump and the sound goes away.
The second is the old climate control settings. The settings switch without moving. Sometimes while I have the AC running through the dash vents it will switch to the defrost setting and then back to AC after a couple minutes. Sometimes it won't stay in the defrost setting and switches to the vents. How to diagnose?
Ford Super Duty (1999-2016) :: Small Electric Pump Noise Coming From Under The Hood On Shutdown
I have a '12 F250 w/ 6.7 diesel. Lately when I turn off the ignition after a few seconds I hear a noise that sounds like a small electric pump coming from under the hood on the passenger side.
This also happened a while back but at the time the service people said they could not get it to do that and it eventually stopped.
Ford F-150 - 1997-2003 :: P0401 Code - Vacuum Lines?
So here's the background. I recently bought this truck. It's a 97 Ford f150 4x4 4.6l 99w vin code. Anyway Driving it home got a p0401. No problem. I Applied vacuum from other vacuum source to EGR engine stalls. So to me passages are clean in the throttle body. I checked to verify and indeed passages are clean. No while doing so I noticed no vacuum was making its way to the dose valve thing. Strange.... So took the line that runs to the passenger fender to dose off and it was impossible to blow air through.
So I cut out the clogged section found solder in the line. I filled the gap I now created using some 5/32 vacuum line reconnected to test and to my anvil still not vacuum. So I disconnected it again. Went directly to where the yellow/orange dose vacuum line connects to at the passenger fender and to my surprise no vacuum there either. No my question is. Am i suppose to have constant vacuum to the dpse or I'm I just being an idiot. And two if I am suppose to when the vacuum line runs into the passange fender where does it go from there and could I have a major issue in my hands?

Time to replace the aging vacuum lines to the 4wd and probably anywhere I can find the old rubber stuff.

I'd like to order a roll so I can make ones like the front hubs longer, stuff like that.

My 1999 F 250 5.4 liter. I know I have a vacuum leak because whenever I accelerate the air conditioning coming from the vents switches to the defroster. So my question is how do I go about finding the leak? My hubs in the front are manual so I know I don't have lines going up there. I do have some mechanical capabilities I've changed water pumps alternators brakes etc. But never anything with vacuum lines or a/c.

View 7 RepliesFord Super Duty (1999-2016) :: Removal Of Vacuum Lines For ESOF?
Truck has been neglected for a while so this upgrade/repair I installed Powerstop brake rotor, caliper, bracket and pads. New Timkin wheel bearing, Moog U-Joints, and new inner/outer axle seals. Also replaced all the brake hoses and the remaining original rusty brake lines. About a month before I replaced the failed Auto/Manual vacuum operated locking hubs with Mile Marker units, which do not need the vacuum line, the drivers side was missing. and was letting water into the wheel bearing. So I decided to plug them and remove the vacuum lines from under the hood as well.
If there is interest I can get pictures of the vacuum lines, and what I changed under the hood. That was pretty self explanatory.
Could not find a google search for the thread size of the vacuum nipple in the knuckle. It is a 3/8"-24 fine thread.

Ford Super Duty (1999-2016) :: 4x4 - Vacuum Lines Starting To Look Brittle
I don't have any leaks at the moment, but after inspecting my vacuum lines they're starting to look brittle and I want to replace them proactively. Is there a kit to do this or should I just cut a section off and take it in to an auto parts store to match the size, and buy it by the foot?
View 2 RepliesFord Ranger / B-Series :: Vacuum Lines Bad On Driver Side / Actuators Won't Disengage Properly
I noticed that one of my vacuum lines was bad on the driver's side. I've done a lot of reading on the 4WD systems and frankly I'm confused now. My understanding is that when in 2WD the solenoid is open pulling a vacuum on the actuators (IWE) which keeps them disengaged. When you switch to 4WD the shift motor on the transfer case sends power to the front wheels and the solenoid turns off the vacuum which engages the actuators sending power to the wheels. Therefore if there is a vacuum leak the actuators won't disengage properly.
Through my trouble shooting I've determined that I think the solenoid is working properly because I'm getting a vacuum when in 2WD and no vacuum in 4WD. I believe that both actuators are engaged and working properly when in 4WD. However, I must not be getting a vacuum to the driver's side actuator (hub) because the line is totally busted up and can't possibly hold a vacuum. However the passenger side line looks good to me. Does this mean that I've been driving around in "3WD"??? I don't seem to have any problems when in 2WD turning (no tire skip or hop).
Ford Excursion :: Water Pump Leak Again - Gasket Deteriorated / Cracked?
I replaced my water pump on my 2000 Excursion 7.3 about six months ago because it was leaking from the little hole underneath. Everything was fine until today I noticed a big stain on my driveway under the front of the truck. I took a look and the new pump is leaking. It seems to be coming from the the back of the water pump where it sits flush against the engine.
Could the gasket have deteriorated or cracked? I bough it from a local parts store called part source, so it should be under warranty. Any thoughts?
Datsun :: 1977 - Possible To Remove Vacuum Lines From AC System
I decided to do some work on the engine bay of my '77 Datsun 280Z. I would like to know whether it is possible to remove the vacuum lines from the system, and if so, what would be the effect on the AC system? If I understand it correctly, the AC selector and mode doors are mechanically operated and vacuum lines assist in opening (i) the air intake door and (ii) the mode door?
