I have a 2001 Ford Ranger 4x4 4.0L. It's been blowing warm air ever since I got it (about a year ago). After doing some research online, I bought a gauge (low side port only) and some R134a. After hooking up the gauge, I got a reading of about 100psi. I'm not very technically inclined about cars, what could be wrong?
View 14 RepliesI have a 94 ranger 5 speed xlt v6 4.0l 288k miles original engine. in the last month the oil pressure has gradually gone way up. a manual gauge shows 65psi at cold start ( in the 90* out side) after a minute of idle it dropped to 60psi, at 2k rpms the psi was 85+. also the water temp has gotten hotter to the point of almost being unsafe. it appears that in the hotter part of the day the psi goes higher. the oil and filter was changed 1200 miles ago. the cooling system has been update in the last year with a new radiator new thermostat. no cross contamination in the fluids, engine runs good other than gauges on dash showing water and oil getting close to unsafe range and manual gauge showing high pressure.
View 14 RepliesI have a 2009 Ranger 2.3 L manual with about 100000 miles. The engine was bogging down and I just found out that the MAF sensor is bad from testing it. In the process, I measured my fuel pressure to be 73 psi (manual says 60-65 psi). So I have two questions:
a.) Is there any chance of just cleaning the MAF sensor. The sensor has zero volts when running and warm (or .02 v) and barely changes when reving the throttle.
b.) Perhaps then the high fuel pressure is an unrelated issue. Is this so high that I must change the regulator as I have to change the pump as well? Might it be some other issue than the regulator which is what the Hayness manual says?
One theory I had for the high fuel pressure is that the bad MAF was leading to bogging and lean conditions and the computer was running the pump more to compensate but I think the computer might run the pump based on fuel pressure not the o2 sensor.
Made a trip to the hardware store yesterday. When I came out, the truck would crank just fine, but wouldn't start (98 4.0L 4x4). Tried adding gas, no luck. I had actually called a wrecker, but it eventually started after sitting for about an hour. All I did differently was hit the gas pedal a couple of times. Thinking it may be a low fuel pressure problem, I took it to autozone this morning (started it about 4 times now with no problems). Checked the fuel pressure, and it sat at a solid 65 lbs at idle. I tried holding the throttle open and it stayed at the same pressure. I forgot to try with the vacuum off.
First off, I've seen some people say 60 lbs is right, but more say it should be at about 45lbs. 45 seems right since the fuel return is on the block, not on the pump. I'm guessing the fuel damper went out, but is there any good way to check it? Also, since the damper is vacuum controlled, would a bad vacuum cause this problem? Third, could high fuel pressure cause it to not start? That's the one I'm most worried about what was wrong there.
I own a 1990 Ford Ranger, 2.3 EFI with an 8 Plug setup and 2WD. It uses a dual-coil system an not a distributor if that means anything here.
Okay, so for the last week I have been experiencing extremely high oil pressures. My gauge would read almost as high as the "H" mark. The smell of burning oil was heavy in the cab from the vents. I took it easy, made sure my oil level was good and I had enough oil, the truck drove rough, but drove decent.
Yesterday, I got done sliding in some mud (not crazy bouncing or anything, just sliding). I stopped at a stop sign, turned around and hit the gas, and the truck died. I thought there were other issues not related to oil, however I noticed that the oil gauge now read about an inch left of the "L"ow mark. If I turned the key, to the "ON" position, the gauge pushed the needle to above the left gauge itself pointing towards about the "8 oclock" area.
Now, my truck will not start. It cranks and cranks and cranks with no start. I called a bunch of mechanics and none of them knew what I should do. AutoZone did not know what do, no one did. Some people said that the oil pump itself had gone out and that would cause the truck not to start and would cause gauge issue. Others said that it might be as small as the Oil Pressure Switch. Firstly, I bought a new Pressure Switch. Have not installed it because I cannot find the damn thing.
Where the switch OFFICIALLY is. I have read on Google that it is on the passenger side, at the rear end of the cylinder head. Other posts say it is by the oil filter...

I think I've tracked my power steering leak to some type of sensor on the pressure line, close to where it connects to the steering box:
I assume this is a pressure sensor? I got no CEL or anything like that when the fluid had leaked down to the level that the pump started whining pretty badly though. As far as I can tell by looking at pictures, the parts store replacement pressure lines do not have this sensor, or any provision to connect a sensor to it: Advance Auto Parts: Power Steering Pressure Hose by Powercraft - Part 71878
I may just put a replacement line on there and leave the sensor plug hanging and see what happens...
1999 F150 .... Been troubleshooting ac on my Dad's truck. Read the FAQ and after going through all the diagnostics on the ac (low-pressure switch, high-pressure switch, ac clutch relay, coil resistance all OK) I found issue with the clutch gap. I removed the washer in the clutch and put everything back together and the clutch is engaging properly now ( the gap is around .020 now) and seems to be working ok. I borrowed a set of gauges from a friend and want to verify the low and high side readings to see if the charge is adequate. Getting about 48F air out of the vents with outside temps around 85F. What the low and high side pressures should be running at that outside temperature?

I changed the fuel filter 20,000 miles ago. This has been a recurring issue anytime my fuel level was low, about 1/4 tank or less, and when the truck was warmed up, hot. The fix in the past was to add fuel and let the truck sit for awhile. Now, today I drove home for lunch and when I tried to start the truck to return to work, it wouldn't start.
Same conditions, low fuel level and it was warmed up. The engine will turn over and start to run with ether in the air box, so it's definitely fuel related. A fuel pressure gauge on the Schrader valve got a zero reading, not even a flicker, and no residual pressure after shut off.
Could this be only a fuel pressure regulator issue? Or should I prepare to replace the fuel pump? Is there a fuse that might be blown?
I have a 2001 Ranger 4.0, 4x4 that just hit 100k and the oil pressure gauge doesn't show a reading for about 1 minute after startup. Also, the check gauge light comes on. What do I replace to fix this and is it something I can do myself? I am mildly handy. Would you worry about fixing it or just let it go because it's obviously getting oil pressure.
View 2 Replies Dad has a 2001 well cared for Mazda B3000 with around 128,000 miles on it. Motor runs fine, so did the tranny up until a couple of weeks ago. The tranny needs a new clutch, throw out bearing, and pressure plate. It was drivable up until about four days ago.
My Dad has been working 6-7 days a week and hasn't had time to tear into the tranny. We just drained the old fluid out and put in new when it first started making the noise it makes. We have priced the parts and was just waiting for my Dad to get a weekend off to tackle the problem. But someone at work told my Dad to bleed the slave cylinder before he tore into the tranny, just to see if it would work.
Well we bled the slave cylinder just like you do brakes. But now the clutch has no pressure, it just goes to the floor. We have tried everything. My dad uses the truck to commute back and forth to work. So, I am looking for any tricks on how we can get pressure back in the clutch so he can get to work.
We noticed that the air conditioner in our 2000 Hyundai Accent isn't as effective as it once was and I began to investigate. My hypothesis was that the car is 10 years old and may just have over time become low on refrigerant. After checking that my car does indeed use a R-134a based system, I purchased a canister of refrigerant with a hose and gauge for connecting the canister. Following the directions on the product, I attached the gauge and operated the A/C at full blast. Initially the pressure read 45 psi which would suggest that the system was probably about where it should be given the outside ambient temperature. I continued to observer the gauge and over a few minutes the pressure rose to around 100 PSI before the compressor stopped turning (the clutch released, so the outside of the pulley turned normally, but the center of the pulley stopped.) As expected the cool air ceased and the blower at this point only moved around the warm air still in the cab.
All I have done at this point is observe the pressure on the low side of A/C system and witnessed the compressor stopping when the pressure got high. My suspicion at this point is there is a much bigger problem for me find? I know I can always take the car to a specialist, but I was really hoping for a simple and economical do it yourself solution.
Wiper problem is that they only work on high. The symptoms are as follow. The relay is working as the controls are ran thru the intermittent steps. I have tried two control switches and they acted the same. So, I believe the problem is in the motor. There doesn't appear to be any wire problems on the plug so it must be inside the motor. Could this be that grease problem inside the motor and it just needs to be cleaned and re-greased?
Radio, Has power to the plug but doesn't work at all. It doesn't appear to have a head unit fuse that I keep reading about. I have not tried to hook it up direct yet but will try that tonight. I am trying to get this truck ready to sell and need to get these items cleared up.
It is a 2001 XLT Extra Cab 4X4 with a 3.0.
I'm trying to add some 134 to the AC to see if it will work at all. it slowly stopped last year. I got a charge hose and a can of just 134a. When I attached the hose the gauge pegs on the high pressure side. I know I'm on the low pressure side and the compressor isn't running. It starts and stops. Should the pressure be that high with the compressor not running?
View 2 RepliesI own a 03' 2.7 Santa Fe (2wd) and when I got home last night i noticed that she was smoking like crazy (not overheating). Opened the hood looked under the car and noticed some fluid spraying on the the exhaust and leaking down from there which was causing the smoke. I put her on jack stands and noticed what looks like to be some hard (i think pressurized) lines that are attached to a connector of some sort in front of the steering rack. What lines are these? Power steering? oil cooler? Transmission related? The fluid that is leaking looks like transmission fluid cause its reddish brown. Ive worked on a few other cars before but not too familiar with Hyundai. When i get home later I will take a pic of this area and post a picture. And it looks like its spraying from the connecting lines (maybe a crush washer gone bad? ) not sure. I can't seem to find any image of this area online either.
View 2 RepliesI have replaced a head gasket on my 2001 civic LX recently. I have drain the coolant and put it back on again. Now I have idle issues, the car starts fine with high RPM (because it is cold) about 5 min latter the RPM changes, it revs low and high (about 2000 rpm) when it should be idling normally. I have taken the radiator cap (before i start the engine) and run it a while with the cap off to purge any air pockets, no luck. Another thing I have realized that there is a pressure build up in the upper and lower radiator hoses when it is running with the radiator cap on. How to fix this problem?
View 13 RepliesMy front driver side brake line broke. It had a typical double flare fitting at the caliper but at the distribution block on the other end it had a flared fitting that would be used on a industrial hydraulic unit. I took it to the NAPA store and they told me to cut the nut off the old line and put it new line and double flare it. I did and it leaks. Do I need a special fitting on the end that goes the distribution block?
View 2 RepliesWhen I bought a used camry 5 years ago and drove it on the highway, my front tire busted and damaged the fender cuz it had too much air!! I wonder if it shows high pressure on my 2010 gen III Prius v with ATP. I know that the tires are special on this v version but still I like to keep a slightly higher pressure in the front ones because the lane keep assist feature works better with higher tire pressure. Summer is coming up so that gets me worried what to do with tire pressures.
View 10 Replies2001 Ranger 4 liter 4 door My driver side window goes up and the electric motor does not stop running when the window reaches its normal upper position. Instead it goes bang-bang-bang until I take my finger off of the switch. I'm guessing there is a limit switch that should disconnect the motor but has failed. The bang-bang (again I'm guessing) probably is some sort of a spring loaded torque limiter to protect the motor. Other than that, the window goes up & down as it normally should. I have no problem digging into the door, except with the window, door lock and outside mirror switches, I don't have a clue regarding how to get the inside door panel off. I know to disconnect the battery 1st.
View 1 RepliesI just had the good fortune of buying a 1988 F250 Diesel (IH 7.3 non turbo) from an older couple - few miles, always garaged and always dealer serviced. It hasnt been driven muvch in the last few years and has only 67K miles.
The air conditioner isnt blowing cold. It was converted to 134a by the dealership in 2000 with all the correct fittings, labels etc - a nice conversion. When I attach a guage to the low side the compressor starts up, the pressure quickly rises to approx 45lbs and what I presume is a high pressure cut off stops the compressor, the system pressure then quickly drops and the compressor restarts. the whole cycle only takes about 15 seconds or so...
I assumed that slow leakage over time had occurred so began by adding a small amount of a combination of 2oz of oil and 2 oz of 134a...I saw no difference in the pressure fluctuations nor the cycle times so shut down the system. There are two valves (needle valves) on both sides of the compressor but they don't look closed.
New owner of a used 2002 Ranger XLT 4x4 (with 59k miles) here (and new to this forum). Having problems with the oil pressure gauge not registering on cold starts (though it registers after the engine warms up).
I know this is nothing more than an idiot light since the gauge isn't really a gauge (inasmuch as it registers in the normal range at 7 psi and stays there unless the pressure goes away).
I've read that this is likely due to the oil pressure switch not functioning properly. I'd like to know where this switch is located on a 4.0 L V6. Other than this, the engine functions normally (though it sucks the gas).
I've got 30 lbs of fuel pressure that drops to 28 if you rev it up a bit on a 1998 ranger 4.0 with a new fuel filter. Haynes manual say it should be 56-72 lbs. Bad news is fuel pressure regulator is in the tanks with the pump. Can the regulator be swapped out or is it one assembly with the fuel pump? Is there anything I should check first?
