Ford Ranger / B-Series :: 1987 - No Power While Accelerating
Jul 29, 2014
1987 ranger 2.9l... My truck had no power while accelerating. We'll I changed fuel pump and filter. And still no power. I bought a computer and it tells me the map sensor is not at normal vaccum levels. The ego sensor is reading always rich. Egr valve not opening. Knock sensor was was going crazy. And computer couldn't raise engine speed above normal idle. Could all this be because of one sensor or should I just change it all.

Well it all started when I was having starter issues my starter died and my solenoid was just clicking and after time there was no power at all to anything in the truck i have replaced the solenoid and starter and check battery and cleaned post and terminals. I am going to replace my negative cable as it was pretty bad but if this still does not work, so what to look for. The truck is an 87 ford ranger 4x4 5 speed with a 2.9....

My brother's 87 ford ranger 2.3L truck began to have problems. It would be running great, then start to misfire, run rough, sputter, shake and loose accelleration then die. Then it wouldn't start back up for a long time, sometimes til the next day. Little by little, the truck would drive a shorter and shorter distance between breakdowns. He first tried some minor work himself, (basic tune up) - replaced his rotor, cap, plugs, air filter, fuel filter, but that didn't fix it. He went to one garage (big mistake), who said the fuel pump pressure was fine but said he found a broken wire on the harness grounding out and it needed new ignition module and replaced it. (Cost was $350.00+), Garage promised to honor any additional work nec if it continued to have the same problem, and would be free of charge.
Five more breakdowns later and two more "better quality ignition modules", new battery terminals, and 1 new computer later, this joker did more unauthorized work and demanded another $200+ besides the fact of breaking his orig agreement "free of charge" if any further problems! Needless to say, second garage fixed the truck by replacing the magnetic pickup, part # DU 30-C (an electrical part that goes in the distributor and pulsates a current to operate the timing) (it does something like that) and the truck has been driven approximately 40-60 miles as of today, (3 days later), without breaking down. All the other times when picked up from incompetent garage, it wouldn't go more than 1 - 7 miles before breaking down and each time they didn't fix it.

I have a 1987 Ford Ranger 2.3L, it's the truck I learned to drive in (stick at 13yo) and the 1st car I crashed too... So now this baby is almost 30 years old and recently had a minor restoration...
Engine was pulled out and all gaskets were changed, spark plugs, wire... All that stuff... It has been running pretty good, however last week a water line broke on the Left side near the spark plugs (if you are looking at the truck)
Since then It has absolutely Zero power. The slightest hill and even when pedal to the floor will lose power. Yesterday went from the start of a hill at 60mph in 4th to 20mph in 2nd because it didn't have the guts to go 1/3 mile uphill... I checked everything I could, and my brother took it to the exhaust guy who made a small hole on the Catalytic Converter and said it was good, but he could tell it was running too rich...
I replaced some of the vacuum lines last night, I found a lose one on the fuel pressure regulator (I think that's what it is, Its towards the engine firewall on top).
Idles beautifully, drives great, no rough shifting, pinging or knocking, no misfires. So that's what has me stumped... Runs great but just no power... Also before water line broke it was running fine with power...

I have a 2002 ford ranger with the 2.3l and 5 speed.
Long story short, previous owner adjusted the time because he accidentally got the motor out of time (he thought it had the belt, not the chain). So he had to take the intake, fuel rails, fan, throttle body, etc. Off to get to the valve cover to re-time it with the timing kit. After it was put back together, it ran awful. I bought it, checked the time with the timing light and it was good. I replaced the spark plugs, and then realized he had forgotten to plug the camshaft positioning sensor back in. So I did, and that did the trick. From start to finish, the truck had those issues for about a year before I got it so it sat up for a little while. I have had it for 2 weeks now.
Now the problem...it idled great. But when I took it out for the test run, 1st gear shifted great, but at about 1700-2000 rpm (depending on the gear), it would almost seem to loose power, and then it would pick back up around 2400-2700 rpm like nothing had happened. You can sort of tell in 2Nd gear, but it is very noticeable in 3rd, 4th, and 5th. If i accelerate pretty slow, it doesn't happen. It only if i try to accelerate at a normal rate or if i am trying to get onto the interstate or pass someone. I ran some seafoam in it thinking maybe it just got gunked up from sitting for so long, but that only through an engine code saying my bank 3 was misfiring.
So I replaced the spark plugs (again), wires, and then the coil pack (the coil pack is what fixed it) and that got the code to go away and for it to stop missing, but the problem still was the same. It would take off great, and then it would seem to almost pause, and then pick power back up again. It wasnt feeling like it isn't getting enough fuel, it just wouldn't hardly pick up speed. It almost feels like I am riding a 2 stroke dirt bike. The power band is ehat should be normal on the truck, and before I hit the power band is how it feels when the truck has its little pausing episode. It's that noticeable to me.
So I thought maybe the fuel filter or sensors need cleaned/replaced..so yesterday I replaced the fuel filter and cleaned every sensor around the top of the engine, including the MAF sensor and made sure all bolts were tight and gaskets were good. I don't see and disconnected vacuum lines and none of them looked dry rotted. The only place air can get in that I see is the air filter box. The screws that hold the top half of the (stock) filter box are missing, so it is not sealed.
But what to check next. My only other thoughts are the catalytic converter (which it doesn't act like it's stopped up) or the fuel pump pressure being off. Also, it does sound like a lifter ticking in the motor, but previous owner said he thinks it did that before all these problems.
Also, right before I bought it, it sounded like the ujoint was squeaking (it rarely does it now) and now it has a crackling sound when accelerating at low-mid rpms coming from the middle or the back of the truck. It sounds similar to when you turn your hot vehicle off and the exhaust makes crackling noises sometimes.

Which transmission came with the 1987 Ranger 2.9L?

I have an 87 v6 ranger with 5 speed that has been sitting for several years. The truck only has 48000 miles on it. The gas tank has been cleaned out and both fuel pumps have been replaced. The injectors were pulled and cleaned...
It will start up and run for about 5 minutes and then will shut off. It will not start after that until the next day and then does the same thing. It starts up and runs then shuts off and can't get it to start again. Could it be some kind of circuit breaker tripping or maybe the ecm. If it is the ecm how do you test it...

I have a friend who drives a 1987 ranger 2.3 4 cyl and is having problems with oil building up in his air cleaner. I thought maybe it was a bad pcv valve or worn out rings. I looked at it and cannot even find a pcv valve on it. it has one hose that runs from the valve cover to the air clean but there' s no valve in it. are the rings shot or what is causing this to happen?

so I have a 1987 2.9L Ranger that likes to stall out when its idling after reaching temperature. Ive replaced all sorts of sensors (IAC, Coolant Temp, and PCV) and so far no luck. I was trying to figure out what the relearn procedure was for the IAC or get an input on any other possible sources of error. I haven't changed TPS yet.
What the engine does is when it gets up to temp, the engine will start to loose speed, and will start to shutter. Then it'll kick back up run fine for a few seconds and drop again, it'll do this for a few minutes then completely just choke out.

I have a 85 bronco 2, but i have no luck with responses in Bronco 2 forum, so here goes. It is the 2.8 carb, manual trans with 109K miles. Idles really well some hesitation when taking off but really bad miss and not power under acceleration. KOEO codes are 31 and 84 CM code 18. I have plugged the vacuum line to the EGR and have noticed a dramatic difference. I have tried to rev the engine and check the vac line to the EGR but I do not feel any vacuum, and at idle the vac line on or off doesn't change things. Any recommendations to whether it is the Sensor or the valve itself and what gives with the 18 code. I am hoping to have timing checked by the weekend.

1987, 2.9 ... I got all my wiring repaired and replaced both the intank pump and the high pressure pump, for a few days it would fire right up as soon as you hit the key but it had a miss (the pumps shut off after a second or two with the key on "RUN"). I tore the throttle body off and cleaned all the carbon out of it, when I put the throttle body back on I noticed that the engine to body ground was loose so I ran a new piece of 4ga from the intake manifold bolt to one of the master cylinder bolts.
After I did this I went to start the truck and no go, the fuel pump turns on with the key but then it wont shut back off until you turn the key off. if you try and start the truck it will crank but wont fire, after about a half hour of cycling the key and cranking it will start to put a little bit then a few tries later it will start but sounds rough when it first fires. I thought it may be a stuck injector so I ran some cleaner through the Schrader valve on the rail. Still have nothing, both pumps do run but still don't shut off after a few seconds like they should and now it wont even try to start.

Recently, today in my 87 Ranger suddenly the engine dies and all electronics in the cab fail.
I noticed under the hood that the fusible link connected to the battery and an orange and black wire was smoking. Tracing this line i found that it leads to the ignition switch, as well as some other places.
There is another fusible link and the junction between the yellow ignition wire and the orange and black wire from the battery. This fusible link also was failed.
I'm planning on replacing the fusible links tomorrow but in case that does not fix it, where to look next.
The problem only occurs when the key is in the ON position. I'm thinking maybe I could do some tests with a multimeter on the ignition switch but am not sure of the details of what I should test for.
Summary: Fusible Links C, and E burn out when the ignition is in the ON position.

I just bought a 87 Ford Ranger 2.9L v6 4x4. It has a tick to it. It doesn't stop, it doesn't increase with acceleration it stays the same. I sprayed some SeaFoam in it and It improved the performance a lot (More horsepower, better reaction to the pedal.) But it is still knocking. I have never tore apart an engine before or messed with lifters or anything. I'm not completely sure how to fix it. I know knocking is not a good thing either.

I was working on my friend's '87 Ranger with 2.9 L V6, and a little bit of dirt fell into the intake manifold through the injector ports and intake ports. I should've cleaned the top of the engine with a shop vac first. Anyway, should I remove the intake manifold, or try to vacuum the bits out? It's pretty oily inside, and they might be stuck to the inside of it, so the vac might not do much. If I have to remove it, do I have to de-mesh the distributor gear to remove it, or does the distributor attach to a splined shaft? After looking at the diagrams, the answer was unclear.

I have a 1987 ford ranger, it has a 2.0L carborated motor and I also have a 1994 ford ranger fuel injected motor I believe it's a 2.3L, I am wondering if the swap will work to put the 94 motor in the 87....

My dash light fuse blew. I checked with a meter and I have a short to ground somewhere in the wiring for the lights. Everything else seems to be working fine.
Is there a copy of the wiring diagram somewhere?
I have the big ford shop manual but I't doesn't have any diagrams. (might be missing pages, I got it off Ebay and the index is missing T-Z).
I have the Haynes but it doesn't have the diagram for the dash lights.

My ranger 2.9 automatic 2WD has an high idle when started for about 6 min, engine can be hot or cold, still get the high idle, then it will drop to around 900-1000. I've changed the Idle control twice, checked EGR function. Replace temp sensor. Disconnected battery for 15 min. No code output.
