Al right i have a 94 ranger 4.0 4x4 auto 186k ... The truck has new bosch double plat plugs gaped .054, new wires, MAF, TPS, FPR, O2 sensors, ECTS and I checked the intake air charge sensor and is fine ....

Ford Ranger / B-Series :: 1990 - No Spark And Not Starting
1990 ranger 2.9 ... I have put about everything new on this ranger. It has no spark, ran fine til i went across a set of railroad tracks, it died 6 months ago and never started again .. Many dollars and many hrs has gone into this thing and still no spark. It will spark when you turn the key on. Crank it and 3 more sparks and thats it. Every electrical piece has been replaced. I've checked and bought relays ,fuel shut off, new distributor pickup coil, rotor, cap, wires, plugs, coil and still no start?

89 2.3l 4x4 will crank just fine but no start. It is getting plenty of fuel. Replaced ignition module,crank sensor,computer, checked all fuses. I've been looking for a broken wire with no luck. Doesn't seem to be getting any power to the coil packs. Truck was not driven very often until a month ago. Started up fine everyday until the no start.

I need getting my Buick to start. It is a 1989 LeSabre Limited with a series 1 3800 engine. I only have spark on cylinders 3 and 6 (paired on ignition coil). I have run tests to see that I have that I have 12 volts to the ignition module, 12 volts out to the crank sensor, signals coming from the crank sensor. I pulled the coil pack and found that I only have a signal on the blue wire supplying 3 and 6. I don't get a signal on the green and yellow wires supplying the other 4 cylinders. My tests would indicate that the ICM is bad. I replaced the ICM and out of desperation the coil pack and I still have the exact same problem. I cleaned the aluminum surface to make sure I have an excellent ground.

I have an '02 Ranger 2.3L 40k miles that will not turn over even with a good battery. When the key is inserted and turned, all the dash lights and headlights come on but the engine does not turn over. Could it be....
*Power Control Module?
*Ignition Module?
*Key?
*Whatever the part is called that reads the Key's security code.
*Clutch Switch?
I am trying to avoid getting the run-around at the dealer and be able to drive to work on Monday!
Ford Ranger / B-Series :: No Power At Cigarette Lighter - Fuse Checks Good?
I have a 96 Ranger . Neither my cigarette lighter or the auxiliary right beneath it works. The fuse checks good at the panel and I also used one of the penlight 12 volt testers and it shows no voltage on the lighter housing. Could there be another fuse under the hood that shares that circuit or do I have an open somewhere and need to tear down the dashboard? I haven't been inside that dashboard since I replace my cluster and the lighter worked after doing so. But I wish to avoid going back in there.

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.

I've been fighting some issues with the truck and decided to do a compression test to decide if I want to try to keep 'Old Yeller' alive or not. I'm all for working on it until I have to dig into the lower end of the motor. I rented a compression tool and the results were a little shocking. I did this test with a slightly warm motor, fuel pump relay pulled, all spark plugs pulled and throttle @ 100 %. Motor turned over 10 times for each cylinder. I even moved all the rubber o-rings on the tool up on the threads to make sure I was getting a good seal.
Cyl 1 - 40
Cyl 2 - 0
Cyl 3 - 0
Cyl 4 - 80
Cyl 5 - 0
Cyl 6 - 60
Needless to say I didn't even bother doing this wet. My only real question is can this be close to accurate. I drive the truck daily. 160k mi on it.
I'm fighting the dreadful P0171 and P0174 codes and after a couple cycles I will get misfire codes. Its low on power (hard to keep @ 70MPH with some wind) and gets 10MPG right now. However it starts and runs and stays consistent (even though it rumbles like it has a nice cam in it).
Is it time to put Old Yeller down ? Are these compression results even remotely accurate ?
Ford Ranger / B-Series :: 2001 V6 Only Runs On 2 Or 3 Cylinders
My 2001 V6 Ford Ranger Edge has 124, 000 miles and always ran very well, Shortly after a minimal attempt to pull a vehicle out of a ditch the vehicle began to run poorly. This may be coincidental as problem did not begin straight away. The engine refused to start at first but now appears to run on 2 or 3 cylinders. I have checked AND CONFIRMED the following:
Spark at all cylinders
Fuel filter replaced
Fuel pump checked
Fuel pressure 56 psi at schrader valve on fuel rail
Fuel inertia cut off valve checked
E_Z start sprayed in feed horn did nothing
I hope to avoid towing it to the dealer,as I recently had a very negative experience doing this with the Honda dealer..
Ford Ranger / B-Series :: 1990 V6 3 Cylinders On Driver Side Not Firing
Is there something that would make the 3 cylinders on the drivers side of a 1990 2.9l not fire? I have spark to the plugs and pressure/fuel at the schrader valve on the fuel rail. The passenger side cylinders are firing fine and the engine runs (roughly) on these 3 cylinders. Truck was running just fine, then all of a sudden, drivers side is dead. Is there a fuse or something that controls these three fuel injectors?

I have a 2003 ford ranger edge with the 3.0l engine. It started acting up today so i brought it to get checked because the check engine light came on. Three codes where pulled p0300, p0306, and p0313. They were multiple/random cylinders misfiring, cylinder 6 misfire, and first misfire at 1000 rpm. I have replaced the plugs and coil and still have the trouble.

Ford Ranger / B-Series :: Erratic Idle / Sporadic Miss / 3 Cylinders On Right Bank Dropping In And Out
Its a 1994 with 4.0, automatic, 4x4. Running fine, parked it, a week later I'm getting a bad but sporadic miss that according to the stealership is the 3 cylinders on the right bank dropping in and out. Driving down the road you can feel them drop out and when they come back its a kick in the pants like a turbo kicked in.
Shop says wires are good, plugs are good, and then lost me when they started talking around in circles and not making much sense.
What could make 3 cylinders all on the same side of the engine drop in and out? This wasn't anything that slowly came on. Fine one day, crap the next. The only thing I did prior to was replace the IAC because it was idling high, it was cruddy inside, and it looked like it was original. It was running fine after that till this issue popped up out of nowhere.
Mileage was claimed to be 178k but I'm beginning to suspect it's probably 278k.
Ford Ranger / B-Series :: Truck Sputters - Cylinders 2 / 3 And 4 Misfiring - Bank 1 And 2 Running Lean
I have a 99 ford ranger xlt 4.0 ohv basically it sputters so bad while driving it sounds like a dump truck but it all started when I changed my o2 sensors but in doing so I broke my heater control valve and when I was going down the road it started sputtering well it started sputtering so I checked the o2 sensors there good and I changed the heater control valve. But nothing so I changed my coil pack spark plugs and wires but still nothing. But on my reader it says cylinders 2,3, and 4 are misfiring and bank 1 and 2 are running lean plus it has a bad aroma of gas in the engine compartment but when it idles its somewhat smooth but when I'm driving it its horrible the sputtering is so bad it takes awhile to get up to speed plus I'm only getting 100 miles to a whole tank that's like 8 or 9 mpg I need to fix this soon. This is my only transportation...

Truck has no spark except when you first turn key on it sparks or right when you let off from cranking it will give one spark. You can be cranking it and nothing and when you let off it kinda acts like it wants to start for a millisecond.

Any way to tell if the ECU is faulty? I hooked my analyzer up to my friends 1988 Ford ranger 2.3L and it wouldn't even detect that the ignition switch was on. He was driving it the other day and is shut off on him while he was making a turn and it wouldn't start back up. We have rebuilt the distributor by replacing the pick-up, rotor button and cap, and we had the ignition module tested and found it was good. We have also replaced the coil. When the ignition is turned to the on position, the fuel pump comes on and never cycles off.

Ford Ranger / B-Series :: 1997 - No Spark / Start When Wet Or Humid Outside
997 2.3 TruckSo this has been an issue for a long time, actually one of the issues I had when I got the truck 3 years ago. After it rains or is extremely humid, my truck does not want to start. Sometimes it will after cranking and cranking and cranking for a while (stopping to cool the starter of course) and other times it won't start.
This time around, it won't start. I cranked it for a little bit and had my dad check for spark while cranking. No spark at all. What should I start looking at? Coils, crank sensor and wires are all newer. As mentioned before, EEC has been replaced. Could it just be bad luck and I got a crap crank sensor? All fuses and grounds are good.
No codes, either except for the occasional misfire code that I get for some reason after pushing in the clutch to decelerate from a higher RPM. It'll fall and start to misfire, but clear up when taking back off.
Ford Ranger / B-Series :: 1998 - No Spark / Cranks But Does Not Fire
My father in law has a 98 4wd, 4.0L that cranks but doesn't fire. We pulled a plug to check for spark....no spark. Possibly coil pack, or crank position sensor?
