Ford Ranger / B-Series :: 1994 - Lifter Knock At Start Up / Throttle Hold Over 3k?
Feb 28, 2013
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.

I have a '94 Ranger XLT with the 4 cylinder 2.3L motor. I recently failed my smog test here in CA because the evap system would not hold pressure. All the emissions were perfect, but it wouldn't hold pressure. I changed the fuel filler neck -- it was cracked -- but there is still a problem somewhere. Is there a diagram that shows where all the hoses are for the evap system? I'm thinking that some other hoses might be cracked since they have been there over 20 years. Is this a good place to start looking or should I be checking something else?

I have a '94 Mazda B3000 3.0L V6. The engine finally gave out at 244,000 miles. I had a used motor installed with approx. 110,000 miles on it. I now hear a knocking sound only when the engine is under load (in gear and accelerating). The knocking is not present while revving the engine while in park or neutral. The transmission was rebuilt last year about this time. I have described this problem to several respected mechanics and they don't know what it could be. What could cause this condition?

I've got an 83 ranger that has proven to be a bit of a head-ache. For starters it's got a persistent oil leak. It's somewhere in the area of the distributor, intake manifold, block region on the backside of the engine, but I can't get back there to see it.
Secondly, the truck only seems to want to start when I give it gas. Even when I use starter fluid, it will only get to an idle if I hold it to the floor when I turn the key. What this might be?

Specs: 2003 Ranger Edge / 3.0 V6 / 5-speed 4WD / 238,000 miles
Yesterday my truck was in the shop for repair. Intake gasket, Transmission fluid change, all heater hoses, thermostat, serp belt and coolant flush. When I picked it up from the shop, which was after closing, I noticed a knocking on start up. From past experience on a different truck, it sounds like a cam that isn't oiling. After a few minutes the knock goes away. I drove for a few miles, turned off the engine and started it back up and no knock this time. This morning I started it, knock was back but went away after a few minutes. Oil was changed about 1500 miles ago. Running pennzoil 5/20 with a K&N filter. Up until yesterday the engine has been completely quiet. Was wonder if something may have clogged the filter or the drain back valve.

2004 auto ranger 120k miles
When I bought it there was a lifter making a tap tap tap. Its not all the time or consistent which makes me feel its a failed lifter as opposed to a rocker arm that is loose. Ive tried the "stuff" in the oil. Seafoam, marvel mystery, etc with no luck. So this coming winter Im going to break it down and replace the lifter.
First question. I havent put a stethoscope on it or used the "hose to ear" method to track down which one it is. Im pretty sure its the right bank in the front. Will it be obvious which one it is when I get it broken down?
Next. At 120k miles should I be worried about the other lifters? Ive never had one fail on anything I own and hardly ever hear them on other cars. I pretty much thought that hydraulic lifters were failproof anymore. Should I be worried about the others?
Next next, do I need to be worried about damage to the pushrod and or rocker arm? Should I be prepared to replace those as well? Finally anything else to be concerned about or consider?

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....

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?

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 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.

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????

I have 05 F250 SD with 150k on it. The engine has the typical cam phaser knock, timing chain slap on start up and occasionally have a noisy lifter. As long as I use fresh 20-40 oil the engine symptoms are less and the engine runs strong. The motor also doesn't leak or burn oil and the plugs were change out about 20k ago.
The truck is still good and is prefect for my needs so to me it's seems worth fixing the needed repairs. What I would like to figure out how far should I take the motor... just have the chains, guides and phasers replaced or buy a rebuilt motor and swap it? I'm thinking just doing the phases and etc would be 1/2 the cost but may not last as long as rebuilt motor. But realistically I might only put 5-7k miles are year on it anyways.

Quick back story I bought a 1999 Ford Ranger It is a 4 cyl with an auto trans the guy said it had some trouble with the tranny (major understatement) he also forgot to mention he cut out the CAT. so running a 4 banger off the header.
When you start the truck it rough idles but you have to hold the gas down til it warms up. You can shift into reverse but it labors the motor and the motor will not up the rpms kinda stays at idle and wants to die no matter how hard you accelerate and you can't move up a slight incline.
When you shift into drive you have to rev the motor to 3 grand an it will catch then move slowly forward. no matter how high the revs go. The fluid levels are a tad above the full level and a bit dark for my liking.
Ok, I used an OBDII scan tool from the parts store and it came up with 3 codes P0351, P0352, P0500. From my internet search the first two seem to be coil related which explains why the motor is running like garbage. The last may or may not have to do with what the tranny is doing.

I too had this problem and tried different gas, gas additives, meticulously inspecting the cooling system to make sure overheating was impossible, found the jumper that allows me to back off timing 2 degrees, checked the computer for error codes, and cleaning the MAF sensor. Nothing really worked.
The solution is to decarbon the engine. It is all described in TSB 01-19-7, dated OCT 01. I did this and END of the problem. Pay attention to the part about not ingesting the PM-3 cleaner too fast to make sure you don't liquid lock your engine. The only important step they forgot was that you will need to replace spark plugs when you're done. You may also want to lay some newspaper under your tailpipe too, as the crud is gonna flow.
The TSB notes that the driver should have "periods of daily operation over 3500RPM to break carbon from cyl heads". They also note that you should NOT use mid-grade or super duper unleaded, as these increase the probability of carbon buildup.
This repair will cost about $30 if you do it yourself; if you can change a flat tire you can do this.

I recently replaced the plugs & wires on my '97 3.0L XLT automatic, and now I'm hearing some pre-ignition (spark knock). Only happens under light load, as in climbing a slight grade on the highway. No CEL, no codes on my code reader. Was not happening before I did the work.
The plugs & wires I removed were the factory originals (AWSF32P & PG, 3 of each), truck only has ~85,000KM (~50,000 Miles) on it. Well maintained, & only used occasionally. The only mod from stock are the wheels & tires, I'm running 215/70 R15 instead of the stock 225/70 R14, the difference in the tire circumference is minimal.
The gap on the old plugs was just over .050", no evidence of any fouling or other problems. The new plugs are Autolite XP104 Iridium, which is what the Autolite catalog calls for. Plug gap was checked & set to .044", midway in the range called for by Ford (.042-.046).
I realize that the narrower gap on the new plugs will cause a slight advance in timing, and I have done a computer reset/relearn as per Paw Paw's instructions. I'm stumped.

03, 2.3 duratec, 163k, new timing chain, plugs (AP104), wires and intake. cleaned MAF, air filter, and ran two cans of sea foam through the intake and its still pinging. its driving me up the wall. truck runs perfect but seems to idle slightly higher and take longer to come down to idle after I got the timing chain and plugs/wires done. I've sprayed starting fluid around on top of the engine looking for vacuum leaks but found nothing. What should I try next?
