Ford Ranger / B-Series :: 1994 - Running Hot - Loss Of Power

So I got everything fixed on my 94 ranger so I thought. Now it runs right on the "L" on the idiot gauge on 90 degree plus days running the AC. Also it seems to lose power at times and not even want to do 70. I think new coils, new plugs and wires may work. I also have an intermittent check engine light that pops up on occasion, but clears when you kill the motor and start it back up. I was really starting to like this truck despite it not being my style(I like square body rangers) and it being a 4 cylinder. I like the MPG but am starting to think the 200k engine may be fading

Ford Ranger / B-Series :: Power Loss When Going Down The Road Now Won't Start Or Run

So, a couple of months ago, my Ranger lost a lot of power going down the road, and when I came to a stop it died, and wouldn't start. So I got it started by roll starting it, made it to a friend's, and then back home. I've put new spark plugs and wires in, and it needed it, badly, but it didn't work. I got a couple of codes off of it,

P0302- Cylinder 2 misfire detected(which I fixed with the spark plugs)
P1443 - which I can't find a definitive answer for
P0500- vehicle speed sensor malfunction
P0171- system to lean (bank 1)

So, the truck will turn over, and if I give it a lot of gas it'll start at stay started for a few minutes, but then cut off. When it is running it's running very very very roughly.

Ford Ranger / B-Series :: 1994 - Coolant Loss / Head Gasket Leaking

I am working on my buddy's 1994 Ranger with a 2.3L I4 that has been going thru a large amount of engine coolant. The trucks has approximately 180,000 miles on it. When I had it parked on concrete I have not seen any signs of coolant on the concrete or any signs of coolant leaking. The next place I checked was inside the cab to see if there was any coolant from the heater core and there was not. The water pump has been replaced a couple of years back. I replaced the spark plugs today and did not see anything on the plugs that I would have thought were signs of coolant in the combustion chambers.

With that being said I have not worked on a vehicle with a leaking head gasket before. Would there be any visible signs on the sparks plugs? If so what would I be looking for? When standing in front of the vehicle with the engine running there is a slight smell of antifreeze being "vaporized". Are there any noted issues with this engine that would cause this? Are there any other things I should check? Could it be a leaking head gasket causing this? If so how can I check for that?

Ford Ranger / B-Series :: 1994 - Won't Start After Warm Up?

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?

Ford Ranger / B-Series :: 1994 4.0 Sometimes Will Crank And Not Start

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.

Ford Ranger / B-Series :: 1994 - Engine Cranks But Won't Start

My kid is using my 94 Ranger with 215,000 miles. It quit while he was on his way to work. Engine cranks but won't start.

Fuel pressure at rail was 12 psi (Key on eng. off). I replaced fuel pump. Pressure at rail up to 20 psi. Still cranks, no start.

I replaced fuel filter. Pressure at rail up to 30 psi. Still cranks, no start.

Replaced distributor cap/rotor and plugs. I have spark at plugs.

Chiltons from 1994 doesn't list a rail fuel pressure. I see new fuel pressure regulators are set at 41 psi. I pulled mine and hooked air to it. It (FPR) cracks at 37 psi. I have lots of flow returning to tank, so I assume the fuel system is working correctly. I've never replaced the timing chain/sprockets. Distributor rotor spins during engine cranking. When I rotate the crank pulley to 0 Top Dead Center the rotor is pointing to #1 on the distributor, so I don't think the timing chain has skipped a tooth on the sprocket??????

Ford Ranger / B-Series :: 1994 3.0 4x4 - No Start / Surging Idle When Hot?

I'm having trouble with my ford ranger. It cold starts fine, and drives fine while cold. Once it warms up the idle is barely keeping it running, or surging 1000-1500 rpms above normal idle. Any gas I apply while hot idling will stall out the motor, and will not restart. It acts like it is very flooded when I try to do a hot start. I pulled the IAC valve off and cleaned it even though it was very clean and actuated properly. I also cleaned my MAF, and that changed nothing. I really do not want to just throw parts at it hoping I guess right before I'm broke. Not sure where to go from here, and I live in Alaska where I am fixing this outside.

Ford Ranger / B-Series :: 1994 4X4 Would Not Start / No Spark And No Fuel Pressure

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?

Ford Ranger / B-Series :: 1994 - Lifter Knock At Start Up / Throttle Hold Over 3k?

I've got a '94 Ranger with the 4.0L OHV and an Automatic trans. When I start, hot or cold, it has quick lifter knock for only a fraction of a second. This same knock comes back if I hold the throttle over 3K with NO LOAD on the engine. With any load, I cannot make it knock. With no load, though, it becomes very loud, especially with more RPMs. at idle and slightly above, there is a slight tick that can only be heard with the bonnet up, and then it is only slightly noticeable. I think that this tick is unrelated, but I figured I should share that information. For oil, I run Pennzoil high mileage 10W-30, changed 3000 miles religiously. Purolator filter, PL30001. I can understand the startup knock, but I can't see why it seems to produce the same knock at high RPMs under NO load.

Ford Ranger / B-Series :: 1994 - Truck Won't Turn Over Just Making Noise Like It Wants To Start

The truck just won't turn over makes a rrrgh rrrgh noice like it wants to start, I push the gas peddle to the floor and I should smell a lot of gas but don't!!! I added oil when it died at the store last night and it started up but the oil stick indicates oil is fine??? Pulled the diode out this morning put it back in the truck would not start just made that noise but turned it off and reseated the diode and it started??? These things may or may not have anything to do with the problem. Could it be electrical or oil pressure gauge sticking or something else that I could tell my mechanic and he could fix so I don't get stuck????

Ford Ranger / B-Series :: 1994 - Sputtering / Back Firing / No Power

Background - I just got done changing a few things... Exhaust Manifold/gasket, battery cables, valve cover gasket, oil cooler gasket and hoses, power steering pump and hoses, and ball joints. Most of this has nothing to do with the issue that came up as I am driving it back to return it to her.

While out on the freeway, I initially notice subtle power losses and surges. These quickly escalate into almost total power loss with back firing, sputtering and much more noticeable surges in power. The check engine light was turning off then on a few times before pretty much deciding to stay on.

So I nurse it back home on back roads due to its inability to maintain freeway speeds. I proceed to check everything I touched paying special attention to the exhaust manifold and surrounding area. The new manifold came from the j/y and was barely used so I had initially just stuck with the O2 sensor that came with it; I changed this to the one the vehicle had previously been employing as it was not exhibiting these symptoms until after the job was done. I also double checked all the hoses, intake tube, wires and connectors; everything is connected.

From here, I research the method of pulling codes on OBD-1 vehicles by making the check engine light flash. It flashed a 111 and a 172 at the same time; the information I could find said the 111 means everything is normal, and the 172 suggested O2 or MAF. I am reasonably sure the O2 is not the problem so I focused on the MAF. Disconnecting it while running seemed to improve the way it idled so via the process of deduction, which also included the consideration of typical symptoms of MAF sensor failure, I proceeded to replacing the MAF sensor which amounted to little improvement.

At this moment in time the check engine light has not returned but it is clearly not in a drive-able state of being. It actually seems to have ever so slightly improved though.

Additionally, the symptoms only exist when the engine is hot and has been driven; it drives normally for 5-10 minutes until it gets to operating temperature then it starts to crap out. After changing the MAF sensor, I let it idle for 20 minutes and it was fine until about 2 minutes into the test drive.

Speculation - I am thinking spark plugs could also be a culprit as its has been forever since a tune-up but the sudden onset of this condition make me doubt this a little; it also has 8 plugs so even if one or two crapped out it should still run better than this I would think.

Ford Ranger / B-Series :: 1998 - Random Loss Of Power

This has happened before on my 98 ranger 2.5. You can drive it 10,000 miles without any issue and then all of a sudden you take off and there's no power but it quickly returns. Within the last year I've changed fuel pump assembly, fuel filter, injectors, cool packs, and plugs. Is it mass air flow? It seemed to happen a lot more after I cleaned it. My scan tool is amateur but it has a maf reading in lbs. What should it be while driving? Fuel pressure is always between 65-72 when I check it within specs according to my book.

Ford Ranger / B-Series :: 1988 - Power Loss Like Coil Getting Bad

Bought my third 88 ranger today, drove it 55 of 60 miles home and it died. It lost power and acted like the coil was going bad. This one is a 2.9 5 speed 4x4. The a/c compressor is gone; but the 365 a/c works okay, or did.

My daughter was following me in her car; by the time we got back with my F150 and a chain, it started and ran until it was a half maile from home then lost power and died again.

Drug it home, put a new coil on and it started and revved up fine. Went to move it a couple of hours later and it will crank with the starter, but not fire.

I am getting 12 volts to the primary side of the coil, is there any way to check the TFI module without taking it off the distributor? (they are so accessable).

Or is there something else that I need to check? I really don't want to just throw money at it, I like to know for sure what is wrong before I buy parts.

Ford Ranger / B-Series :: Intermittent / Complete Loss Of Power Only When Driving

Background- 2000 Ranger, 3.0L 2WD 170,000mi. This truck is not my daily driver, i try to drive it once a week.

I've never had this issue before... I drove all over town yesterday; multiple stops, no issue. Today i go to do the same thing and upon accelerating out of the driveway i lose all power for about 3 seconds. I get power back for about 3 seconds then lose it again. This continues for as longs as i'm driving. Also, no CEL. I go back to the house to look things over, can't find anything staring me in the face really.

Truck idles fine and the issue is not present when i run up the RPMs in park. I've been reading some other threads about similar issues and most replies begin with checking the regular maintenance stuff i.e. TB, MAF, IACV, pcv, etc. It seems like a complete loss of fuel or spark...but only when in gear with constant throttle???
