2.9

I have been having alot of problems with my engine running rough and not running at all. I have been digging through wires and relays. I cracked open my eec to find that pin 46 was fried. I know multiple things run to this pin since it is a signal ground. What could cause this to burn up so it...

Im having trouble with my engine not running right. It takes a long time to start. The fuel pump kicks on when the clutch is pressed but shuts off when released. The motor runs rich and blows out alot of smoke. Im currently looking at the eec relay. Im getting constant power of 13 volts from the...

Hey guys. I've rebuilt my 88 ranger 2.9 l from top to bottom. My engine is running rich. I've replaced the idle air control valve, the o2, sensor, the pressure regulator twice, New injectors, New coolant sensor, map sensor twice, the computer and I've also shot all the wires. I did fuel pressure...

Looking for some insight on a voltage drop on TPS. Truck is 87 ranger 2.9 v6, I’m currently getting a bit of erratic idle and acceleration. I read to check tps , and at about half way to WOT my voltage drops when I get around 1.98, drops to 0.00 and then back up to 2.1. Head scratcher at this...

hey everyone i have a 2.9 v6 with over 400,000k on it, i just finished my manual swap and a one wire alternator upgrade ever since then i cant get it to idle properly with the map sensor plugged in it just makes it rev out and when its unpluged it just dumps fuel and idles fine i think it may...

Hey there, looking for some help to track down the cause of a misfire on cylinder 4&5 on 87 Ranger 2.9 v6 Pulled the truck out of the garage today noticed it had less power starting off, little less noticeable at higher speeds. When I got back home and popped the hood the engine had a a lil...

I picked up an old Ranger that had more issues than I bargained for and am trying to figure out what to do with it. Details here: https://portland.craigslist.org/mlt/cto/d/portland-1987-ford-ranger-stx-4x4-29l/7864807461.html My impulse is to cut my losses and sell it. Then I remembered how...

I was doing the valve stem seals on my 89 Bronco II. When I noticed on the front most pushrod on cylinder 1 fresh coolant in the lifter valley. You can see it in the photo here. I pumped some of it out and it is as if I came straight out of the coolant reservoir. Did not see any coolant...

Can someone please direct me to a picture that shows the MAP sensor location on an '87 2.9l in a BII? Thanks!

Sorry if this is in the wrong place or has been covered. I searched the forum and didn't see my issue. That said. I got my 87 2.9l 5sp xlt a few months ago and have been chasing problems ever since. Currently it's dying and then doesn't want to start. I tried 2 TPS and with both the voltage...

Howdy, first time posting here, I’m Jayce. I daily a 1986 Eddie Bauer bronco 2 with 85k miles and I love it but this 2.9 is perplexing me. The engine starts only if you floor it as you turn the key and quickly let off the throttle. I’ve replaced the computer as my stock one wasn’t outputting...

Got a bush find a 1987 ford ranger 4x4 STX club cab me and wife have already named “Moose”. Having trouble getting it going but I know it wants to run. First problem fuel pump relay. I have experience with my other 1987 ranger and the first thing I noticed was the ground wire for the relays was...

So I bought a 88 STX 2.9 with the 5 speed, this is my first truck I've had no issues till now. Now I've got a crazy misfire and I can't seem to find it, I've done plugs wires but its still missing. When it misses there seems to be large gaps between firing and looses power. I fixed a few vacuum...

Hello, So I have 3 guages that don't work like they used to. The first is the tachometer. Sometimes it reads really high and then drops to 0. Then sometimes it comes back from 0 to normal and sometimes does repeated drops to zero and then back up then back and forth between a reading and zero...

Old pump was leaking and whining so I replaced it. Installed new pump and tried to bleed the system with the car off and the fluid level didn't go down. So I kept turning it then decided to start the car to see if that helped, still no fluid movement. Tried to drive the car and had zero power...

Hi there, I finally scored on a some JBA Headers along with a Y-pipe for my 88' Ranger XLT 2.9 '5 Speed 4WD. I do not tow or race this truck. I drive it on a nice day or on the weekend so I think a 2.25in single out the back would be best for my application. I did have the thought of doing...

Hello all, been browsing the forums but my first post here. Recently acquired a 1987 Ranger XLT, 2.9L, ext cab, auto. Truck sat for a year before I got it, so it took a few love taps on the starter to get her alive. Upon startup, the engine immediately went full throttle, nothing touching the...

Hi there, I bought a all original and very well kept Extended Cab 88' XLT 4x4 2.9L '5 Speed with 106k miles last year in August. Truck runs great without any issues and still does now. I've been in the Ranger game for a while now and know the 2.9 Cologne is not very popular and aftermarket...

I have a 1987 Bronco II. I am not a mechanic. I replaced the TFI Module. I Screwed something up. I was getting some slight hesitation when I pressed the gas, the idle was a little rough, and a little rough on start up and going from drive to park. I figured the ignition system. I checked the...

1989 bronco II. I just rebuilt and installed the original 2.9. While attempting the initial startup and break in I got code 95 "fuel pump circuit open – EEC processor to motor ground". I haven't been able to find anything specific on how to fix this issue or problems it would cause. Any help...
