Ford Ranger / B-Series :: 1994 4.0L - Starts / Stumbles And Dies Soon After
Mar 10, 2015
Ole girl finally let me down, or I let it down at 224,000mi. Started just fine one early cold morning and in about 30 seconds started stumbling and down for the count she went. Acts like it wants to run but will only stumble.
Checked inertia switch (ok) and all vacuum lines/caps appear to be fine. I was kind of due for new set of plugs/wires and a fuel filter. Replaced all didn't see any problems with the old when pulling. She will run for a few seconds, but stumbles and not smooth while running. Checked fuel pressure KOEO 40psi steady. I can hear fuel pump charge system per as usual.
Seeing as it is super cab checked for chafing on wiring to fuel pump under cab. Looks fine. I've heard tell could be alternator, which seems odd to me. Wondering if it would be worth pulling it off and taking it in for a bench test? Maybe I missed something. I know the intake gasket is suspect.

Well I replaced the spark plugs on my 2000 ranger 2.5 l . Because the tabs for cylinder 3 and 4 I had to take of the intake. After all this i go to start it and it runs fine. When I drive it up the street it starts knocking and stumbles and dies. Now it runs with some sort of knock. Should I take it to a mechanic?

94 Mazda B4000. V6 4x4 manual
After engine has ran about an hour, I make a stop at location, then on startup engine has a hard time staying idle after engine it's warm. Cold start idles fine, hot start it dies out. I must rev gas for truck to stay on. What could this be?

I have a 2005 ranger SOHC 4.0 new rebuilt engine It starts then dies after a few seconds then doesn't start at all unless it sets for a few hours or over night and will do same thing. It has 60 psi on fuel rail, good spark I'm starting to think my PCM is causing all this?

My 2003 2.3L used to run bad... it had a lot of lag to it when i would try to accelerate. The check engine light was on so i got it checked, and the reading said o2 sensor high voltage or something like that... anyways, i purchased a new sensor (i researched, and found there is only an upstream o2 sensor), replaced it, and the truck ran WAY better, no more lag during acceleration, it was crisp. As i was driving home one day, i was accelerating up a hill, and at about 4000 RPM, the truck almost dies and starts sputtering.
The check engine light started flashing, so i new it was serious, but luckily i was able to make it back to my house. When i got home, i looked under the hood and noticed that #2 & #3 spark plug caps had popped off the spark plugs. What I don't understand is what would have caused that to happen in the first place.... Is it a clogged Catalytic convertor, or is the o2 sensor bad.... Ive read different opinions and technical diagnostic possibilities, but man, i don't want to throw a bunch of money at a truck that I'm really going to have for a few more months. but I need to get it fixed in the mean time.

I've got an issue with my 92 2.3 ranger.... sitting at idle for 30 or so seconds it starts to chug and sometimes dies.... I can hit the throttle and its fine for another 30 or so seconds.... while cruising on the freeway after about 30 minutes it starts to cut out badly... let out of throttle for a few seconds and it clears up and drives fine...
Here's the part that has me confused... pulled codes yesterday using a innova scan tool...
koeo were 4, 10, and 538...
koer were 111, 10, 157, 158, 181, 327, 328, and 334....
How does it give me a 111 pass code and then still come up with all the other codes? I am thinking my ecu may be screwed.....

'02 Ranger XLT, extended cab, 4X4, 4.0L SOHC, 5-speed manual, 114K miles.
Problem has occurred twice. After extended run time and engine fully heated, when I get home and shut it down, then attempt to restart within a short period of time, the engine starts very briefly, then begins shuddering violently and dies within a few seconds. Re-attempts to start result in a very shuddering attempt to run for a couple seconds, and then it dies. After a couple of re-attempts, it doesn't even attempt to start; just cranks over with no results. Has to sit about 7-8 hours before it will restart.
No OBD II codes; Passed, no codes shown. I purchased a crank position sensor, but haven't installed it yet: just a stab in the dark after hearing other people's experiences with other vehicles.
First occurrence followed a lengthy trip in heavy stop-and-go traffic. Shut it down when I got home, then attempted to re-start after a few minutes to run a short errand. Sat for two days without any re-attempts; then restarted and ran fine on first try a couple days later.
Second occurrence followed a couple hours of hitting yard sales with the neighbor, in which time I did not shut the truck down; just left it idling while we perused the sales, for fear it wouldn't re-start. Reckon it's a good thing I did, 'cause when we got home and I shut it down and attempted to leave again shortly thereafter, it malfunctioned as described.
Retries failed after sitting 4-5 hours, but after eleven hours of sitting, it started right up and ran normally.

I just replaced the water pump and put it all back together, now it won't run well enough to drive. Checked vacuum system, all sensor connections, hoses, gas cap, changed fuel filter, I can hear the fuel pump kick in, reset system with battery disconnected and have looked at everything I can think of so far.
Now - starts fine, idles about 10 seconds and then begins to idle rough and dies. If I use the throttle I can often keep the idle up, but then backfires or acts like no fuel and again dies. Used fuel cleaner and made sure there was plenty fuel in tank.
I am looking at replacing sensors at this point but which one first?? They get a bit expensive real quick.

My 94 ranger, 3.0 v6 began to sputter and jerk about a month ago. It does this when ever give more then lite throttle up until about 3000 rpm. I have replaced plugs, wires, coil and cleaned the air flow sensor. I feel like this has worked a little but the problem is still definitely present. When I hit 3k rpm if feels lie the truck begins to run correctly and almost like it had a power ban much like a dirtbike, but again it's just the truck running correct.. And above 3k rpm it runs great... and every so often the problem will completely disappear for 5 minutes or so, then come right back.

Working on a friends 94 ranger, 2.3 L with codes 218 and 998. Chiltons manual does not even show this code. Code is for Loss of Ignition Diagnostic Monitor (IDM)/left side. What exactly is this? Can't find anything that explains the IDM.
998 means a hard fault.

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?

Having a slight issue with my ranger. So I bought this truck out of a junkyard about a month ago, its a 94 4x4 with a 4.0 and a five speed. When I bought the truck the motor was blown so a few weeks ago i replaced it with a 4.0 from an aerostar van I had laying around. Right after I changed it the truck was running good with no issues, until a few days ago going to work the truck started hesitating going up a hill. Now the truck does it all the time, sitting at idle the truck runs smooth as silk, at half throttle it does it the worst but when you mash the peddle to the floor it clears up and runs good.
So far I've replaced the plugs, wires, coil pack, mass air sensor, throttle position sensor, and the fuel pressure regulator to try and fix it but nothing has worked. I've checked the fuel pressure it has 30 at idle and 40 with the vacuum hose pulled off of the regulator, I even taped the gauge to the windshield and went for a ride and there was no drop in pressure when it started acting up. a few other things i have done were plugged all the vacuum ports to rule out a leak, reset the computer and checked for codes. the only code that came up was 522. So I think my next step is going to be buy new oxygen sensors ? But my question is wouldn't the check engine light come on if it was an oxygen sensor ?

Got a problem with the '94 Ranger. Something keeps draining the battery. For reference, the truck is an XL, manual 4x4, 4.0L, 5-speed. I've been trying to keep driving it so I could try and diagnose the issue. At first, as long as I cranked it every day, it stayed charged up, but now it has gotten worse. It will run down in an hour or two. I know figuring this kind of problem out is tough, but I thought maybe some others of you may have experience in this area that might benefit me.
Based on a gut feeling, my first idea was that there was something going on inside the AC compressor. So, I disconnected the compressor, but that wasn't it. My plan at the moment is to replace the wiring harness between the battery and the starter. The current harness is pieced together (not my doing), and whether it fixes this problem or not, it needs to be done. Another thing I've thought about is the ignition switch. It acts "funny" to me, but it has never really given any trouble.
My son needs to take this vehicle back to college with him in a couple weeks, and I need to get it figured out.

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.

Just bought this truck. When I test drove it no "check engine" light came on, but after purchase driving home is came on and then off many times. It only comes on at high rpm/speed. I have my trusty ODBII scanner but realize that this 1994 was pre-ODBII. How can I figure out what the CEL is about?

I didn't really know where else to turn (no pun intended) every time I turn my wheel to the right the truck sputters out and dies, i checked the ignition switch, tightened her up and shes still killing the engine when i turn right. All other power remains on stereo, car charger etc. its not so bad on continuous turns i can just pop the clutch but for stopping and turning its a huge issue. Why turning left is fine but right kills the engine..wondering if maybe the prongs on the ignition switch may be bad?

Engine runs rough at idle. Two plugs are black and just replaced head gaskets. I installed new short block and new heads six months ago. I can't seem to figure out the problem and I would like to trouble shoot more before tearing heads off and going any further.
