Ford Ranger / B-Series :: 1994 - High Oil Pressure / Water Temperature?
Jun 30, 2013
I 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.

My oil pressure gauge does not work. I was told that it's most likely the sensor. Where would I find this to change it out?

Sons 94 ranger 4.0 4x4 Auto 185k got him to work yesterday but would not start to bring him home. No spark, checked with timing light, and no fuel pressure. Searched and read alot of tips from Pawpaw so I tried a few things with no luck. Swapped the relays around, inspected coil pack and plugs. CEL was not on and goes out while cranking. I have a OBD scan tool but this truck must be too old or I need finding plug. Crank sensor maybe?

I have a '94 Ranger XLT with the 4 cylinder 2.3L motor. I recently failed my smog test here in CA because the evap system would not hold pressure. All the emissions were perfect, but it wouldn't hold pressure. I changed the fuel filler neck -- it was cracked -- but there is still a problem somewhere. Is there a diagram that shows where all the hoses are for the evap system? I'm thinking that some other hoses might be cracked since they have been there over 20 years. Is this a good place to start looking or should I be checking something else?

My 94 B4000 (4.0L ohv)is acting weird. If I let it sit for more than a day, it won't start. I pop the intake tube off, squirt some gas in the plenum, and away she goes. It starts all day long after that. I can hear the fuel pump running. Is there a possibility there is a fuel pressure regulator leaking down, kinda like a pump losing it's prime? Or am I looking at dropping the tank for a new fuel pump??? It's getting close to winter up here (gonna snow anytime) and I don't need this kind of trouble when it's cold and snowy.

I 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...

My 94 ranger, 3.0 v6 began to sputter and jerk about a month ago. It does this when ever give more then lite throttle up until about 3000 rpm. I have replaced plugs, wires, coil and cleaned the air flow sensor. I feel like this has worked a little but the problem is still definitely present. When I hit 3k rpm if feels lie the truck begins to run correctly and almost like it had a power ban much like a dirtbike, but again it's just the truck running correct.. And above 3k rpm it runs great... and every so often the problem will completely disappear for 5 minutes or so, then come right back.

Working on a friends 94 ranger, 2.3 L with codes 218 and 998. Chiltons manual does not even show this code. Code is for Loss of Ignition Diagnostic Monitor (IDM)/left side. What exactly is this? Can't find anything that explains the IDM.
998 means a hard fault.

I have a 2011 xlt extended cab with a 2.3l 4 cylinder. The truck is great... I put 120,000 miles on it in under a year.
But about a month ago the temperature gauge started malfunctioning. for what ever reason -- the truck is NOT over heating-- the gauge would increase past the "H" and then the temperature light would come on. Because the truck thinks it's overheating -- the engine goes into a "safe mode" and runs with no power. When i shut the motor off and turn it back on temperature gauge resets and the truck will run fine.
Then in another 50 or 100 miles it will do it again. Why is it doing this? I took it to the dealer here in Columbus, Ohio and the mechanic installed a new thermostat and a new "control modulator" (and a part -- not really sure what it is called) anyway, the truck is doing the same thing and the mechanic still does not know

Where the temp sensor for the rear view mirror is located. My truck is a 2011 Ranger with the 4.0 liter, AC, automatic and 4x4. I think it is somewhere by the headlights but not sure.

I have a 1994 Ford Ranger 4.0L 4x4, 130,000. I love this truck but about a year ago it started not starting after it warmed up short distances in the summertime? It start right up on cold crank...Runs smooth idles like a champ...but if i shut it off..wont start for 20 to 40 min??? It doesn't happen in the winter months??? So I changed the fuel pump, filter, relays. I feel like it has something to do with the Ignition Control Module. Would that come up in a code?

Having a slight issue with my ranger. So I bought this truck out of a junkyard about a month ago, its a 94 4x4 with a 4.0 and a five speed. When I bought the truck the motor was blown so a few weeks ago i replaced it with a 4.0 from an aerostar van I had laying around. Right after I changed it the truck was running good with no issues, until a few days ago going to work the truck started hesitating going up a hill. Now the truck does it all the time, sitting at idle the truck runs smooth as silk, at half throttle it does it the worst but when you mash the peddle to the floor it clears up and runs good.
So far I've replaced the plugs, wires, coil pack, mass air sensor, throttle position sensor, and the fuel pressure regulator to try and fix it but nothing has worked. I've checked the fuel pressure it has 30 at idle and 40 with the vacuum hose pulled off of the regulator, I even taped the gauge to the windshield and went for a ride and there was no drop in pressure when it started acting up. a few other things i have done were plugged all the vacuum ports to rule out a leak, reset the computer and checked for codes. the only code that came up was 522. So I think my next step is going to be buy new oxygen sensors ? But my question is wouldn't the check engine light come on if it was an oxygen sensor ?

Got a problem with the '94 Ranger. Something keeps draining the battery. For reference, the truck is an XL, manual 4x4, 4.0L, 5-speed. I've been trying to keep driving it so I could try and diagnose the issue. At first, as long as I cranked it every day, it stayed charged up, but now it has gotten worse. It will run down in an hour or two. I know figuring this kind of problem out is tough, but I thought maybe some others of you may have experience in this area that might benefit me.
Based on a gut feeling, my first idea was that there was something going on inside the AC compressor. So, I disconnected the compressor, but that wasn't it. My plan at the moment is to replace the wiring harness between the battery and the starter. The current harness is pieced together (not my doing), and whether it fixes this problem or not, it needs to be done. Another thing I've thought about is the ignition switch. It acts "funny" to me, but it has never really given any trouble.
My son needs to take this vehicle back to college with him in a couple weeks, and I need to get it figured out.

94 Ranger, 4.0, Automatic, 280k miles. Normally starts and always runs fine. Sometimes will crank and not start. Fuel pump replaced Feb. 2015 and again Dec. 2016. Have had it towed 3 times. Always starts when it gets to the mechanic. Sort of reminds me of vapor lock on the old cars with carbs, because if it sits long enough after not starting, it will start, no problem. Never died out or even coughed when running and plenty of power. When I take off the gas cap, it sucks in air like a whale. Twice I did that and it will not start right away, but if it sits for an hour or so, it starts no problem. Just bought a new gas cap 10 minutes ago and looked in a Haynes manual and a " gas tank vapor valve assembly" is mentioned. I don't want to change parts just to see what happens. Mechanics say there are no codes shown.

I have a 1994 Ford Ranger XLT xcab with a 4.0 engine.It will take off and drive in the freezing cold but when it warms up it will only go in reverse.Once in awhile it will go into drive.What seems to be the problem. I had also backed up over a railroad tie in an icy parking lot but still drove away.
