Ford Ranger / B-Series :: Where Is The Oil Pressure Switch Located
Dec 1, 2009
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).

Apparently, top secret location of the oil pressure switch on the 1997 Ranger 4.0?

I've got a 2008 Ranger FX4, 4.0L with manual transmission. Recently I noticed that I have no reverse lights. I have to parallel park on busy streets from time to time, so this is a safety issue that I need to fix.
I checked the bulbs, both seem fine - would be unlikely that both bulbs would die simultaneously. I checked the fuse. Again unlikely unless the reverse lights were on their own independent circuit. 10A fuse looks fine too.
Last thing I can think of is a switch. I checked my Haynes Manual, there is no mention of it, which is odd, usually my manual is quite good. Where the switch is located? Any experience with swapping this out?

I have a 1999 ford ranger and I believe my Clutch safety starting switch is going out. Some times I push my clutch in and truck starts fine other times it will not turn over so I stomp clutch and then it starts. My question is, is there any way to bypass this switch?

In my 1999 Ranger, I can flip the air outlet switch to cause the air to exit either up, down, or straight out -- except that most of the time the air WILL NOT come straight out the dashboard ducts. I am assuming that there is some kind of diverter valve inside the dash that is intermittently working, but I do not know how to get to it. Do I remove the radio panel? If so, how? Or is there a way to get to it some other way, like from underneath or through the glove box? Does it just need a shot of WD-40 to free it up?

I have an 88 ranger 2.9 manual trans. The clutch safety switch wires melted (red with light blue) 2 come off the ignition, I traced the one to the clutch switch and replaced. My problem is my book says the other goes to " electronic shift control module", I can't find this module and I can't seem to chase wire as it gets lost in wire loom.

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?

Ok so my dad has been using my 98 while I was fixing his 92 4.0. I had the 92 perfect and then someone pulled in front of me and totaled it out. Well now I got my 98 back and it's all messed up. Check engine is on p0171. Fuel pressure test done and it's steady 40-42 psi. I remember last year I checked it was like 68-72 psi. It hasn't been a year or two since fuel pump and strainer were replaced. Filter probably 15,000 miles ago. It's currently running good sometimes it cuts off when you start it then next time it stays running. Is this another fuel pump failure? How much longer will it last on 40 psi? The fuel lines and tank have 336,000 miles, engine maybe 150,000 and injectors have about 20,000 miles on them.

What is the likely culprit? No other electrical issues, brake light quit working when brake is depressed, all other lights work including blinkers/running/head. Was going to break out a wiring diagram....

My buddy's 1998 4.0L Ranger caught fire from the dreaded brake switch shorting on the master cylinder. In his defense, he's only owned the truck less than a week and had no clue of the recall. The damage is mainly to the wire harnesses on the driver's side.
Rebuild the wiring. What other years of the Rangers I can pull the wiring harnesses from? Or if the 3.0 harness will work?

The cruise control switch on my 2000 Ranger just broke. It looks like you have to remove the airbag to access it. How is that accessed? It looks like there are 2 plugs on the back of the wheel that need to be removed.

I have a 98 Ranger 2wd reg cab 2.3L 5sp. Recently the airbag warning light was blinking 2-7 which indicates bad lamp in passenger airbag deactivation switch. Since the lamp has no numbers or markings on it, and my repair manual has no schematic on that part, where I can find the ma, wattage or ohm rating of the lamp? Or a part number / source for a replacement lamp?

I have a 95 Ranger 2.3 with a manual tranny. In the past I have had problems with this truck not starting do to a bad inertia switch and numerous fuel pumps. A couple of weeks ago I pulled the truck off of the driveway into the street and let it set there for a few hours. When I went to put it back on the driveway it would not start. I got it pushed on the side of the garage. I did my normal routine of doing a pressure check. I had no fuel pressure so I assumed that it was the fuel pump (as usual) so I dropped the tank and changed the pump.
I got it back together and it still wouldn't start. I checked the fuel pressure and the manifold still had 0. So I started my diagnostic. I have power from the fuse to the fuel pump relay. I then checked the wiring at the inertia switch and found that there is no voltage with the key on at the supply side of the inertia wiring. I verified continuity between power distribution block and the inertia switch. I put in a new fuel pump relay and it still has no fuel rail pressure and there still is no electric signal at the inertia switch. Where to go from here?

2001 Ranger, 108,000 miles, good regular maintenance per the Ford Schedule. 4.0L manual trans.
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 97 Splash with the 3.0, oil pressure goes up to about the middle of the gauge after startup, however, it stays there whatever I do, warm/cold, idle/5500 rpm. Is it supposed to be like that?

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?

1985 2.3L... New fuel pump And fuel pump relay, problem was happening before new parts. the wires at inertia switch continue to get hot switch has been removed. The heat continues to under the hood where there is some so rt of connecting link and heat stops.what the is this link for, it doesn't look like A fusible link?? Saw a similar post here about a fuel pump shutting down and wires getting hot. Same problem.

I am losing residual fuel pressure on my 1996 ranger 2wd, 3.0, V6. Acts fuel starved after sitting for awhile, cranks ok turn key off starts up, sometimes i have to do this twice.

Got a 1986 Ranger 2.3 EFI 5 speed that I have owned since it was almost new and will never let it go. 290,000 mls and still running strong "except". Noticed the last couple of months that when I start it cold it fires right off. If I start it hot it always takes 3 tries and always goes on the third try except....on occasion it will not start at all. It is random and after I let it cool a bit (about 30 min) it will start. Over the years I have replace many of the fuel system components (fuel tank pump, high press. pump, inline filter and canister filter, fuel press regulator) but wondering what else might be the problem.
I put a pressure tester on it the other day and when I selected the key to start the pump would spool up to build pressure and shut off. The press gauge would register that but the pressure would immediately go back to zero. After start up it would hold a constant 30psi at all rpm,s. Shut the engine off and pressure drops right down to zero. Shouldn't the system hold pressure for at least a while after shut down? Could this be the problem with my sluggish starts? What would be the normal fuel pressure? Can't seem to find it in my Haynes manual. Once running it runs great.

I have a 2002 Ranger V6 3000 with 100K miles. Can I add a higher viscosity oil since my pressure gauge is acting up. I changed the sending switch twice but the gauge still acts up occasionally. I was thinking of adding 10/ 30 on my next oil change. I do live in the area where the air temp is quite high in the summer. The truck runs well except for the oil gauge, in my opinion, is giving false readings.
