Found out the hard way that the 4wd does not work on this new stupid truck. I've been troubleshooting the solenoids and confirmed that the 2wd solenoid gets grounded and will read ~12V when switched to 4wd; however, the 2wd solenoid always remains grounded and will always read 12V across the plug no matter if it's in 2wd,4hi,4lo. What would cause this? It seems that I would have vacuum going to the front differential from both the 2wd and 4wd solenoids at the same time, thus not allowing it to go into 4wd. BTW, this is on a '98, 4.6, turn dial 4wd

Ford F-150 - 1997-2003 :: 2000 - Bad Starter Solenoid Relay?
My truck has started fine every time I've turned the key except for last night after work. I got in had all the lights on the dash and dome lights. I turned the key and nothing. Not even a click. Hooked it up to a company truck and it fired right up and ran fine. Drove home shut off and then started it a little later and it started fine. Then this morning it wouldn't start. I hooked up the jump pack and still nothing. I drove my fusion to work and when I got home I went out and it fired right up like nothing happened. Does the work sometimes not work other times sound like the solenoid on the firewall? 2000 4x4 4.6 auto 253k miles

Do I have to drop the valve body to get to the shift solenoid? Is there only one solenoid? Anything special or tricky I should know about?
Ford F-150 - 1997-2003 :: No Crank / Starts Only When Solenoid Is Jumped - Slow Starter
I am having some weird issues with my 2000 F150. When I turn the key all the dash lights go out and no start. Ran 2 wires from the solenoid to a switch and it will eventually start. The starter will start real slow almost like the battery is almost dead and then speeds up more and more till it eventually starts. After it starts the theft light stays on the whole time. At this point I have no clue what is going on.

On my 97, just had a new engine installed. Suddenly the Lo presser AC switch died. Now the Start Solenoid (I think) just clicks sometimes. Is this Solenoid on the Firewall the Start Solenoid?

I have a 99 f150 and it won't shift out of park. The taillights work and I tried to turn the key forward and move shifter to neutral but it didn't work. Is it the switch on the brake pedal or the interlock solenoid by the shifter?

I have a 2010 f 250 super-duty and i cannot get vacuum past the solenoid mounted on top of the radiator. Ford has given me nothing but bad advice. I know i have a vacuum leak after the solenoid and need to replace the lines going to the two hubs but when i switch on the 4wd and hook up a vacuum gauge the vacuum is good up to the solenoid about 12 inches. i constantly have 12 volts going to the center lead but nothing else in the other two leads either in 4 high, 4 low, or 2wd. Am I missing something here? shouldn't there be a voltage change when i turn the switch to 4wd to actuate the vacuum solenoid to let the vacuum pass thru the solenoid? I have tried replacing the solenoid but that did not work. Also use rubber vacuum line and make at down to the hubs?

Ok so I was looking at my blend door actuator motor to see if it was working. Just took off the bottom vent cover, turned key on and moved the air mixture to see if the motor worked. (it didn't) Then I went to start the truck and all I get is the solenoid on the firewall click each time I turn the key. I put a meter on the opposite side of solenoid and I see 12v across the solenoid. I can't image i did anything while playing around by the blend door actuator motor. I guess I'm looking for confirmation that the next logical step is starter and starter solenoid. Is there anything else I could be missing? is there anything else in that circuit between the solenoid on the firewall and the starter? I also cleaned the battery terminals and the terminals down on the starter solenoid. I also tapped the starter a bunch and put a charger on battery and tried jumping the truck too. Everything else works.

I have a 2003 F150 supercrew 4x4 and I'm on my 3rd - 4wd vacuum actuator this winter so far. Somehow water is getting into the actuator itself mounted on the axle and then when it gets cold enough it freezes up and won't work until the heat from the engine thaws it out and then the 4x4 will engage.
Every time I've changed it I have found the part to have about a quarter cup of water in it. and can't figure out where the water may be entering these things. There also was no moisture in the vacuum lines when I blew them out.
I've been using the Dorman brand replacements from O'Reilly, they have a lifetime quarantee but I'm sick of swapping them out every month...
Ford F-150 - 1997-2003 :: Vacuum Controlled 4x4 Not Working
I'm working on a 03 Lariat F150 with vac. controlled 4x4 (I'm new to this one). Transfer case works, ft drive shaft turns, but the front axle wont engage. The servo works, and the linkage is tight on the shaft, and the shaft turns back and forth, and the ft axle can be engage manually by working the small lever back and forth with the servo disconnected, but when zip-tied in place it doesn't stay in 4x4, so something is broken, worn out, or disconnected inside the housing.
Also I repositioned the servo back a bit with a spacer to make sure it wasn't a length of travel issue, and is not - the problem is definitely inside - the linkage feels sloppy when manipulated with the servo off.
Since Ive never had one of these apart I thought Id ask first (also a new thing for me), so I'd know what parts to get (I don't live "in town"), and I figger this isn't the first one of these to break. So I am sitting down - what am I in for??? It looks pretty straight forward, but somehow I doubt it is...
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?

It has been since the 80's that I have attempted to do any work on a vehicle. How do I find a vacuum leak and where is my vacuum canister. I am assuming that it is a vacuum leak for anytime my engine has a load on it the air stops coming out of the dash vents and goes to the defrost vents. I have an 2000 F150 with the large engine with about 112,000 miles.

View 14 RepliesFord F-150 - 1997-2003 :: P0401 OBD2 Code / Vacuum Leaks
I've had a 0401 code on my truck for the last two years. I've replaced the EGR valve and the dpfe sensor a couple of times, with fomoco parts. Ive also cleaned out the egr tube that comes off the exhaust manifold. In this time I also discovered a couple of vacuum leaks and replaced those. I changed the pcv valve, tried running 93 octane gas, and had a mechanic friend run a special smoke through the vacuum lines to find more leaks. Also put a brand new gas cap. I have an obd computer and cleared the code repeatedly but the light always returns.
