Ford Fuel System :: 2002 Explorer - When Accelerate / Take Off From A Light It Hesitates
Jul 5, 2017
In the last month or so I'very had trouble with my 2002 Explorer having trouble accelerating. When I take off from a light it hesitates badly. It feels like it's got air in the tank. It does it every time I need to accelerate, including coming around turns. I'very put in fuel injector cleaner and it works fine for a little while, but then has the same issue. Yesterday morning it wouldn't turn over in the morning. I changed out the battery, but I had a similar issue of not turning over. It eventually did. I was wondering if the two might be related. Could it be a fuel pump or fuel pump relay?

2004 Sports Trac Got a check engine light: a code P0913. The truck , once in a while, hesitates like it not getting fuel. Is this a fuel pump problem or something else?

My 02 F150 4.6 has 84K miles on it, and started stumbling/hesitating during accellartion about three weeks ago. Before this problem started (about 2,000 miles ago), I installed a new fuel filter and air filter. Since I noticed the problem, I installed new plugs. The problem didn't go away, so today I checked the fuel pressure. At idle the pressure is 32psi with the vacuum line left on the fuel pressure regulator (30-45 is normal as per Chilton's), and 42 with the vacuum line off (40-50 is normal as per Chilton's). I also had someone else rev the engine so I could observe, and found that the fuel pressure went as low as 28 when the engine speed was quickly increased. The standing fuel line pressure is 30 (30 is normal as per Chilton's) Does this sound like a fuel pump problem, or is there something else that I'm missing.

I have a 2002 for explorer 4wd 4.0 it won't accelerate. it's fine to 25, but it pings, and won't go over 40. I've changed to the plugs, wires, coil pack and fuel filter. I've also checked the fuel pressure, and it's 65psi. no codes are being set. I've been told plugged cat, but they're welded on, and no way to test them...

I have a 2002 explorer 2wd. I am trying to find an answer for this thumping noise as I accelerate. My first thought was a tire. I took them to be checked and had one replaced but all are good and less than 5k miles on them. I feel it in the pedals and in the steering wheel. The repetitive sound increasing with speed. I have, in the last 2 weeks, changed front rotors and pads with no difference in sound but good brakes now. And today replaced the drivers side upper ball joint and the front ds wheel hub assy. And no difference. What may be the problem?

Well I was recharging my a/c yesterday because the system was low so I used one of them 24oz cans and now I am getting cold air out of my passenger side and luke warm air out of my driver side vents. Also if I switch to the different vents I don't get anything out of the floor only. I get air out when I select it, but it's coming out of the defrost. Other than that everything else works just fine, just no floor. I've read issues with the blend doors but my vehicle doesn't have the dual climate controls so I'm at a loss...

I have a 2002 ford explore 4.0 sport 4wd. I have a problem with my car, one day I tried starting the car and it didn't want to start. So i replaced the fuel filter and the car started. then after starting it a few times it didn't want to start anymore, so i took of the fuel tank (thinking bad gas, and there was stuff in the gas) so i take out the old gas out and put new gas, and bought a new fuel pump and filter, and when i put the gas tank back on the car, it still didnt want to start, so i take the fuel pump and find a random battery and connected it to the fuel pump and the pump spins so it works. I connected the pump to the car by itself not it the fuel tank (from underneath the car) and i was under the car to see if the pump turns on and someone tuned the car on, and the pump doesn't turn on (doesn't spin or anything). Long Story short, what i should do? Also I was looking for the fuel pump fuse and couldn't find it (thinking it might be the fuse) what is the fuse number or where its located.. i know where the fuel pump relay is, but just not the fuse. Why the pump wouldn't turned on??? The pic is how my fuse box looks like(there are many different version of the fuse box just wanted to show you how mine looks)...

My 1992 Ranger has a 2.3L 4cyl 100hp engine with 207k miles. It occasionally hesitates when beginning to accelerate but never when at idle or when driving at speed. I don't even know where to begin. The engine has had consistent maintenance and runs well otherwise. This hesitation makes me afraid that it will damage the drive train somewhere. I'd like to at least know what the problem is even if I can't fix it myself because I've done most of the work on the engine.

My wifes 2002 explorer stopped taking fuel at the gas station. You can only put about 1/10 of a gallon in before it clicks off. I have already dropped the tank and checked the fill and vent tubes, and looked inside both of the charcoal canisters on top of the tank. Everything looks perfectly fine?

My parent's bought a 2002 Explorer 4.0 V6 very early, either late '01 or early '02 when it first came out. Besides the dash blackout (which I found a fix for, need to do) it's been plauged latley (since Nov/Dec 2010) with the intermittent issue of when... You turn the key on to start, you dont hear the fuel pump enguage, thus no start. Get towed, it works like a champ.
It's blown a fuse 1 or 2 times cause of this, had the fuel pump recently replaced (dec/jan this year) and just did it again. Our local Ford dealership figured the fuel pump went bad from sitting, the vehicle only has about 33k miles on it (dad dont drive much). What appears to be a bad fuel pump, only to have it get towed, or sit overnight and start like nothing ever happened?
Dad's ranting about not trusting the vehicle anymore, he's 80yrs old so I can't blame him for wanting to feel comfortable with knowing his vehicle should start, but it is a machine, they do break but we cant seem to get this fixed.

I've got a 2002 Ford Sports Trac that won't start ! It will crank till battery dies but is not getting fuel. I have had it towed 4 times in the past year. of the 4 times,this last time it wont start. Every time that I have had it towed back to my house and dropped in the driveway it has started up with no problems. It will run for a few months or more.This last time it would not.
Could this be an electrical problem.Maybe loose ground somewhere or something else. Would like to rule out some things before investing in a fuel filter or fuel pump. Would hate to buy new FuelPump and that not be the problem. Can't find free wiring diaghrams for this issue.

I have a '99 E-350 6.8L. Where is the check valve that maintains fuel pressure on the system?
I have been experiencing a starting issue when the engine is hot. Cold starts are usually fine. I've replaced the in-tank fuel pump (pump only, not the assembly) to no avail. I was out of town and didn't have access to a fuel pressure gauge when the problem started so I couldn't say what I had prior to replacing the pump. But now, with a new pump, when I check pressure, I get about 40 psi when I first cycle the key on, but it drops right back to zero as soon as the pump shuts off. If I cycle the key on a few times, sometimes I can get it to hold pressure at about 32 psi, and it starts fine. When I shut if off, it goes back to zero psi, sometimes gradually, like a bleed down, and sometimes immediately.
My conclusion from this was that the check valve was bad. I was told it was part of the in tank fuel pump assembly. Since I didn't replace the entire assembly, this made sense. So I just dropped the tank back down, but I don't see anything as part of the pump assembly that serves as a check valve. There is a rubber nipple on the end of the return line, but I don't see how that can hold any significant pressure.
So, before I go out and spend another couple hundred bucks on the complete fuel pump assembly, which apparently can't be purchased without the actual pump, I thought I'd ask. Where is the check valve that holds the pressure in the fuel system?
BTW, I also have replaced the fuel rail pressure regulator, but it made no difference (I went there first since that was much easier than dropping the fuel tank a second time).

I have owned this explorer since new. It is an XLT 4 wheel drive always driven in "automatic" position. When I back up out of a parking place there is (sometimes) a noticeable momentary restriction on the right side as if I had run over something. There is no noise accompanying this. I have to be turning while backing up for this to occur. It sort of feels like the right front brake is somehow activated. Condition does not occur when backing straight. I have had the car to two different Ford dealers and they say they can find nothing wrong.

The 2.8 V6 car sometimes hesitates when trying to accelerate. It even has what feel like 'misses' at idle. No codes except catalytic convertor below efficency bank 2. I suspect it could be a bad o2. I looked at vag com, 311-2 and found...

What measuring blocks should I be looking at? Weird that the car is 'bogging' or 'hesitating' without a misfire being reported.

My sister in law just got into an accident today because her 2006 Explorer hesitates and dies sometimes off the line. Check engine light will come on, and won't go apparently. If she shuts it off and restarts, it will usually work for a little while again. Today, it happened when she took off on a green light, it stalled out and the guy behind her rear ended her. She isn't real happy with her Ford.

We have a 2003 Explorer Sportrac and the fuel cap light came on. Then ck engine light came on. took it to a dealer to check it out. Said it has a fuel pressure issue. could be the cap or something in the fuel tank. it needs a pressure check they said. cleared codes and put new factory fuel cap on. 2 weeks later it happened again. We just had in the dealership...

I have an 01 Elantra Gls with perplexing issues. The car starts at 3000 rpms, and continues to bounce between 2k and 3.5k in both park and neutral. when I put it in reverse i get a very hard shift. It actually jerks the whole car. in drive and reverse, it idles around 1.5k it hesitates quite a bit to accelerate. All fluid levels are right and don't smell burnt. it takes me 10 mins to put 4 gallons of gas in. if i pump too fast it shoots back at me. i randomly smell gas while driving. Im hoping these problems are a couple of issue I can handle at home. i just wanted some input before i buy the manual. thinking vacuum lines maf sensor.

I just replaced the trans in my 02 sport trac and have no speedometer and ABS light is on now. I made sure all connections on trans were tight and I didn't mess with speedometer sensor seeing how it is on the rear diff on this truck. spent two weekends replacing this thing and am not at all happy with the results. By the way i did it all on my back. No vehicle lift or trans lift.
