Ford - Ranger :: 2000 V6 - CEL Code Saying Both Banks Running Lean
I have a 2000 Ranger, with a 4.0 V6, 4X4, with 175,000 miles and it still runs great except the check engine light is on and it is saying that both banks are lean. I put in new plugs, all 3 O2 sensors, cleaned the MAF and checked for vacuum leaks, all to no avail...

1998 ranger 4.0L. I ran my scanner on my truck to day and my 2 bank 1 sensors seem to be bouncing between .150 and .700 but my bank 1 sensor 2 seems to be stuck at 680-720 and not bouncing, is this normal?
I did pull a code po135 heater circuit malfunction BANK 1 SENSOR 1 ...
Also I am not sure where my fuel trims should be...
My
ST1 10.0
LT1 25.0
ST2 12.0
LT2 25.0
closed loop.
When I first got the truck I pulled codes for lean bank 1 and 2 also a cylinder #4 misfire and the bank 1 sensor 1 heater circuit. I reset the codes and the heater circuit bank 1 sensor 1 popped the mil light in 5 min. So I am starting with the o2 sensors. I've not found any vacuum leaks at this point.
Ford Ranger / B-Series :: 1990 - Rough Start - Running Lean?
]I recently bought a 1990 ford ranger with a 2.9 @187,000 miles. That being said I went through and changed a few vacuum lines, the oil, air filter, pcv/grommet, and fuel filter.
The problem is it hates to start. I could crank on it for 10 seconds and not a single thing. Sometimes if i turn the key to the off position, wait a second, and try again, Ill get the truck to fire. When it does fire up it just reeks of the lean exhaust. It also gives me some hesitation when I rev it. I did a fuel pressure test (KOEO) last night and it gave me 32 psi and within a minute the needle fell to about 25 psi. I hear the fuel pump run for only 2-3 seconds too.
I've already pulled the MAF off and cleaned it, replaced the TPS, and did a fuel pressure test. The fuel filter is brand new
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...

Ford Fuel System :: 2003 F150 - Service Light Randomly Comes On / Code For Left Bank Running Lean
2003 f150 supercrew with 166,000 miles on it. Daily driver. Service light randomly comes on and when code reader was put to it shows "left bank running lean." Will clear it and will randomly come back on. Truck seems to be running fine. No issues engine. Bad sensor? Or bad injector? Maybe way to test?

5.4 L, Engine runs if primed at the intake. Fuel pump can be heard running but no fuel gets to the engine. Truck is mint and being sold real cheap due to this issue.
Fuel Pump? Filter? Both? I haven't seen the truck, a friend is considering buying it and rolling the dice it is a quick fix. Fuel is in the tank .....

View 14 RepliesFord Ranger / B-Series :: 1998 - Low Fuel Pressure If Rev Up A Bit
I've got 30 lbs of fuel pressure that drops to 28 if you rev it up a bit on a 1998 ranger 4.0 with a new fuel filter. Haynes manual say it should be 56-72 lbs. Bad news is fuel pressure regulator is in the tanks with the pump. Can the regulator be swapped out or is it one assembly with the fuel pump? Is there anything I should check first?
View 4 RepliesFord Ranger / B-Series :: 1998 2.5 - Fuel Pressure Down To 40 PSI?
Ok so my dad has been using my 98 while I was fixing his 92 4.0. I had the 92 perfect and then someone pulled in front of me and totaled it out. Well now I got my 98 back and it's all messed up. Check engine is on p0171. Fuel pressure test done and it's steady 40-42 psi. I remember last year I checked it was like 68-72 psi. It hasn't been a year or two since fuel pump and strainer were replaced. Filter probably 15,000 miles ago. It's currently running good sometimes it cuts off when you start it then next time it stays running. Is this another fuel pump failure? How much longer will it last on 40 psi? The fuel lines and tank have 336,000 miles, engine maybe 150,000 and injectors have about 20,000 miles on them.
View 4 RepliesFord Ranger / B-Series :: 1998 4.0L Cranks But No Start / High Fuel Pressure
Made a trip to the hardware store yesterday. When I came out, the truck would crank just fine, but wouldn't start (98 4.0L 4x4). Tried adding gas, no luck. I had actually called a wrecker, but it eventually started after sitting for about an hour. All I did differently was hit the gas pedal a couple of times. Thinking it may be a low fuel pressure problem, I took it to autozone this morning (started it about 4 times now with no problems). Checked the fuel pressure, and it sat at a solid 65 lbs at idle. I tried holding the throttle open and it stayed at the same pressure. I forgot to try with the vacuum off.
First off, I've seen some people say 60 lbs is right, but more say it should be at about 45lbs. 45 seems right since the fuel return is on the block, not on the pump. I'm guessing the fuel damper went out, but is there any good way to check it? Also, since the damper is vacuum controlled, would a bad vacuum cause this problem? Third, could high fuel pressure cause it to not start? That's the one I'm most worried about what was wrong there.

View 1 RepliesFord Ranger / B-Series :: 2002 - No Fuel Pressure With The Power On And Engine Not Running
I have a 2002 Ranger with a 3.0/auto with about 180K on it. It runs good but for the past 6 months I have had a problem starting it. It does the same thing hot or cold but is a LITTLE easier when cold. It is very hard to start, you have to grind the started for about 30 seconds then it starts right up.
I checked to see if I could hear the fuel pump when the power is turned on and yes I can. But after checking the fuel pressure, there is no fuel pressure with the power on and the engine not running. Once the engine starts, there is about 65-68 pounds of fuel pressure - and the truck runs just fine. Starting is the only problem.
I was told I had to replace the fuel pump. Is the electric pump in the tank the ONLY fuel pump on the truck, or does it have a combination of the electric/tank pump and a mechanical pump on the engine?
Saturn - SL2 :: 1998 - Fuel Leakage When Stop And Keep The Car Running
1998 Saturn SL2, after I replaced the fuel pump, the pump-in gas hose started leaking. I have replaced this hose 3 times and it still leaks, especially when you stop and keep the car running. After about 10 minutes, the fuel starts shooting out just below the fuel intake hole. What is wrong? What should I do to correct this?
View 2 RepliesFord Ranger / B-Series :: 1992 2.3L - Sputtered Briefly And Motor Quit Running - Fuel Pump Bad?
Truck quit running yesterday suddenly and unexpectedly. It sputtered briefly and the motor total quit running. I pulled over and tried to start and it briefly fired but then totally quit. Got towed home. And now testing to see what all to repair..Thinking fuel.
I don't get any codes from the tester with KOEO..just the good to go etc..no codes or the good to go 111..etc. Guess this problem can't be identified without motor running.
My wiring diagram doesn't give me all for my Calif car..I don't see where the relay is but my fuses are all good, and I'm getting voltage when I crank the motor at that inside firewall switch on both its wires(incoming/outgoing)..forget what its called..Inertia Switch?..that will shut off fuel pump during accident or impact etc. And I've read that this switch is upstream of the relay(if I read that post correctly) so guessing it's the pump itself that is bad.
Does that sound right? Should I go ahead and pull the fuel tank etc and replace the pump? Or is there more testing I should do? When I turn the ignition key on..the pump makes zero sound. That's not the way it normally operates. Usually with the key on the fuel pump comes on momentarily and I can hear it. Forget how to drain the fuel tank etc..I don't see a drain plug? I did it once many years ago..but forget how?

Ford - Ranger :: Check Engine Light Is On Saying Too Lean
I have a 2001 Ford Ranger 2WD XLT. How many oxygen sensors it has? I bought four (two upstream and two downstream) but my mechanic said there was only one downstream and installed three. However, the check engine light is back on saying "Too Lean." Is it possible that they missed one of them or that all three were simply bad?
