Ford F-150 - 1997-2003 :: Enable 4x4 Full Time?
Jan 7, 2017
Quick question. If you unplug the vacuum lines from the solenoids will it enable the 4x4? Is there a way to enable the 4x4 full time?

C/K :: 1997 K2500 Suburban 4x4 Auto 454 - Fuel Gauge Reading Full All The Time?
As title really, it's a 1997 K2500 Suburban 4x4 auto 454. I haven't used the sub for a while but got in it the other day and it fired up all fine and I then looked to see what fuel I had left only to see the needle right over to full. Well I know it is nearly empty and I've never had the guts to fill the thing or should that be had the funds to fill it to the top, so know it is wrong. I got under the truck and unclipped the rear most wiring connector just infront of the fuel tank but the gauge still reads full. I suspect either the gauge is faulty (so is there anyway of checking) or the sender in the tank or wires in the tank have shorted (again anyway of testing without removing the tank).

I have a 2002 supercrew 5.4 triton. My coolant temp gauge is acting up. When it starts up its obviously in the cold range but when the truck begins to get up to temp, the gauge only goes up 1/4 full. What it can be?

I have a 2001 F150 Supercrew (5.4 V8, 2WD,Auto trans) and recently when we fill the gas tank, the fuel tank doesn't go all the way up to the "full" line. Don't know if this matters but: about a year 1/2 ago in a little town (while on vacation), we broke down and the trouble was the fuel pump. The little town did have a small auto-parts store, and luckily had the fuel pump we needed. Unfortunately we didn't have much as far as tools and we wound up tearing/cutting the filler hose and the vent line.
The little auto store did not have the correct rubber filler & vent hoses for my truck and would take a few days get in stock. We changed out the entire fuel pump and sender unit, and were able to modify some rubber hoses for a new filler & vent line hose. Everything worked great for a year 1/2 but in the last few weeks we have noticed that when we fill the tank, the gas gauge does not go all the way up to the "F" line to show full. With the price of gas, it is important to know exactly how much is really in the tank. Also, is there a battery in the ceiling console for the temperature and compass? Ours just stopped working yesterday.
Ford F-150 - 1997-2003 :: Fuel Gauge Malfunction - Jump Up All The Way To Full When Started
I have a 97' F-150 4.6 L and I've been having some fuel gauge issues.... I filled up my tank up and I drove it 130 miles and it still said full tank... even when I had 1/2 I would start it and every time I started it it would jump up all the way to full and slowly drop down. Then randomly last night it started working... I noticed as I hit rough patches in the road and bumps it would usually fluctuate, but it would also fluctuate up... It read I have 3/4 tank last night and I go to start it today and its back up to full! I don't understand... Wouldn't a bad sending unit just stop all together?

I have a 2000 F150 4WD 5.4 running Extremely rich to bank one. The O2 sensors for bank 1 are reading lean(0-50 mV) Bank two is completely unaffected. New plugs in Bank one, 3 new coils in bank one, all pvc lines checked with good vacuum. Previous codes : P0171, P0301-3. The Truck will barely move. Would a small leak up stream of the O2 sensors cause this?

Last summer my A/C and blower stopped working while I was driving on a hot day in July. After replacing blower resistor, the fan works but still no A/C. I tried recharging refrigerant but the pressure in the lines was too high. Also it didn't seem A/C compressor was working either. I suffered through the hot summer only to find when winter came the Heat quit working as well. I noticed antifreeze smell in cabin and put liquid aluminum to stop the leak and still no heat. I planned on pulling the dash and replacing the heater core but wondered while the dash is off could there be something to replace in here on the A/C as well?
View 5 RepliesFord A/C :: No AC And Heat Is On Full All The Time
I just picked up a beautiful 98 Ranger and the only thing I can find wrong with it is a HVAC problem. I bought the truck through the owners brother and they informed me that the AC would work if you "moved something under the dash".
So far, this is what I know:
The temperature out of the vents is full hot, all the time meaning even with the temp control all the way down to cool with the mode selector (Max AC/AC/ Vent/ Off etc.) in any position, all you get is max temp hot air out of the vents. The mode selector does seem to work in as much as it can re- direct the air to the proper outlets when it it operated.
At first I started looking at the AC system itself but now I think it's a control problem. The AC clutch relay, fuse, low pressure switch, clutch field coil, static refrig. pressure and power to the clutch circuit all look OK.
I poked around under the hood looking for vacuum leaks but there was nothing obvious and like I said, the mode selector works, so there's some source of vacuum for them. Also, The hot water valve is actuated when the selector is on the MAX AC or OFF positions as it should be.
Does this sound like a blend door problem? A bad temperature control? I am not well versed in this system and I'm wondering why even if the blend door is stuck or broken (an assumption), the AC compressor will not come on. I have already checked both the selector and the temperature controls to make sure they weren't stripped and spinning on their shafts.

My 2002 Ford F-150 4x4 4.6L 5speed strangely has a time delay in starting now. A delay in TIME and not the usually chucking along waiting to start. Or simply I turn the key and a second or two passes before anything starts to happen and it fires right up. Was wondering a few months ago, if my clutch sensor was going out but then it cleared up once I put a new battery in it although at the same time the weather warmed also. Bad connection somewhere, bad ignition switch, or bad clutch position sensor – I could go in each of these directions. Thought maybe the security in the key was doing it too but both keys have the same problem. No codes also.

I have a '97 F150 4x4 with the 5.4L engine and automatic transmission. The tranny's been slipping on and off for a couple of years. It started when it was hot outside, I had been driving a long ways, and I was trompin' on the gas to pass someone. Still, the slips were rare. As it got worse during the hot summer months, I just minimized my long-distance travels.
I recently took it to a transmission mechanic. Like some of the feedback to posts in here, he felt it was a problem with the engine - because we had a bad EGR valve signal on the computer. (We still flushed the fluid. I later replaced the EGR and the DPFE. Another mechanic went through everything, replaced some valves that had something to do with the EGR, and feels the engine is 100% (and it runs very, very smooth). For those that will bring it up - I have replaced all of the coils (though it's been a few years). Having actually replaced some numerous times over the years, I can feel when one is bad (of course, the 'check engine' light as well). Lastly, we've replaced all bulbs in the dash so they are all working as well. Also, the transmission is not leaking. The computer system is giving us no errors/throwing codes.
After a couple of weeks, I happened to drive the truck a long distance one day and it started slipping. It got bad enough that it was slipping every time going from first to second gear. It would usually engage as I took my foot off the gas. Since then, because I haven't driven long distances, I have not had a problem.
The transmission mechanic thinks it's still an engine issue. He also mentioned a mechanical/electrical switch system on the side of the transmission (?). Give me a list of things to look at.
Ford F-150 - 1997-2003 :: Starter Time Delay When Key Turned?
2000 f150 4x4 5.4auto tranny.
When I turn the key, sometimes i have a time delay before the starter kicks in. I replaced the relay on the firewall and no change. A couple of days ago I started the truck but the starter did not turn off when the key was released. I had to turn the key to off then back to run to get the starter to stop. Now today, I nearly got stranded by it. It took several attempts to get the starter to kick in.
To me this seems like a relay sticking. What should I try next?
Ford F-150 - 1997-2003 :: Vibration / Truck Is Bouncing Most Of The Time At 37 MPH
I have a 4.6 01 F150 with 3.08 rear end I got back in Sept. In Nov. I replaced the timing chain/guides and brakes/rotors all the way around. I have also flushed the cooling sys. and replaced all the coil packs/plugs in Nov. About 2 months ago I started feeling a vibration(feels like the truck is bouncing most of the time not bad but I know something isnt right) at ~37MPH. Not always bad but 98% of the time you can feel it.
I feel it at other speeds sometimes also. 2% of the time I dont feel anything. It had older tires and I got a new set ~ 3 weeks ago and its the same. A couple days ago I put a GoPro under it and filmed the driveshaft and it does seem to be bent some. What might be my issue or things I can check myself? One other note is the previous owner did use the truck to haul a horse trailer some and I know now that rear end was not the best for that! Truck has 210K on it and engine was replaced at ~ 150K

My 97 f-150 starts up every time.........the first time. After I drive for awhile and shut it off it gives me a hard time starting. It just cranks over but wont start. If I give it gas it catches and tries to start but dies out right away after I let go of the key. Sometimes after up to 10 tries and 20 minutes later it starts up again, so far! Also there is a gas smell, but I am thinking that's because of putting the gas pedal to the floor. could it be plugs? i bought it with 180,000 miles on it. I pulled a plug and it does look pretty rough so I am going to change em tomorrow.
The parts store calls out iridium plugs. the guy told me any plugs will work. said the only difference is the mileage you get out of em.
50,000 on regular plugs
100,000 on platinum
150,000 on iridium
Not sure that's the case but I bought platinum. I changed the plugs and wires and it runs great now. stopped for gas yesterday and still had to put the pedal to the floor for it to start. only one try and it started tho...... what next?
Ford F-150 - 1997-2003 :: EGR Open All The Time / PO171 And PO174 Codes
Everything started with the typical lean bank 1 and bank 2 codes. I started at the basics change fuel filter PCV Hose & Valve clean the MAF changed air temp sensor(it was cheap). Still had same po171&po174 codes. Bought a obdll reader. After 3 weeks of nothing being accomplished I bit the bullet and took it to Ford for a diagnostic and they said it was definitely the intake gaskets.
I changed the gaskets and now this has gotten worse! I started the truck after reassembly and it ran like crap!
Checked everything and everywhere and could find nothing wrong. I then took off the vacuum line to the EGR and everything smoothed out. I didn't mess around and replaced the EGR the DPFE and the vacuum solenoid.
It still runs like crap especially at idle. I did the tests with my digital meter and found the vacuum solenoid is calling the EGR to be open all the time. I suspect that this would be the fault of the PCM? What should be my next course of action?
