Ford Ranger / B-Series :: 1994 - Won't Start After Warm Up?
May 17, 2012
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?

I have a 1994 Ford Ranger XLT xcab with a 4.0 engine.It will take off and drive in the freezing cold but when it warms up it will only go in reverse.Once in awhile it will go into drive.What seems to be the problem. I had also backed up over a railroad tie in an icy parking lot but still drove away.

I have a huge problem. My 94 ranger 2.3L 5 speed manual transmission, has problems with idoling while it's cold, has no power going uphill and stalls when I slow down to stop. This is all after putting a new motor in. The old one was running ok with 310,000 but lagging bad. I figured with the driving I do, a new motor wouldn't be a bad thing. Boy, was I wrong. It has been a nightmare. But once the truck is up to operating temperature, it runs so smooth you wouldn't think there was a problem. But let it cool off, restart, and boom! There it is. We have changed so many parts and sensors with absolutely no change to the original problem. It's very frustrating. I just can't let this problem win. I will figure it out.

I have 1994 ranger 2.3 2wd will not start when key is turned to start position - when clutch is depressed there is a click from fender mounted solenoid but it never cranks motor or starter--I need wiring diagram to trace origin of wire on starter solenoid because it does not have 12volts on it--when I jumper 12v on it and have it in neutral it starts up and runs but no voltage and no start with key....

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.

My 03 ranger with a 2.3 I4 does not want to restart when it is above about 80 deg outside and engine is warm. Will crank, but as soon as fuel in line runs out it stalls, like a vapor lock. After about 45 mins can push start normally( has manual trans) but have to wait about 2 hours to use starter to start.

2002 Ranger XLT auto 3.0 will not start after it has run awhile, Was very intermittent at first sometimes six months would pass, sits for and hour or so and would start right up and run great. Lately it is becoming more frequent. Good fuel press, good spark, I have changed the coil pack, fuel relay, filter , am at a loss.

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??????

My son's Ranger wouldn't start today, turns over fine, added gas to make sure it wasn't out still no hit.
Other than fuel pump (he said he couldn't hear it) what things should he check? I'll check back in the morning.

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'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.

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?

1994 Ranger .. Last wednesday I had to get a jump because the lights where left on. Everything was normal on thursday. Friday morning. I went to go start the truck and notice that it would try once to start and then try a second time and it would start. Today I was driving it. The check engine light came on and when I get the RPMs up to shift up, I would loose all power and have to wait till it gets down below 10mph before I would get the power back.

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.

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????

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.

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.
