My friends 2000(I think) explorer With the 4.0 86k has burnt up two pumps in two weeks. This last one only lasted a day. There was over half a tank of fuel in it when installed and only drove it to work and back, about 50 miles. Next morning he went to leave, nothing. Pump won't run. Checked fuses and relays they were okay. Why would this be happening?
View 2 RepliesI have a 2000 4.0 Explorer that sometimes will not start. It has happened on cool mornings as well as hot days after I shut it off, for example, shutting it off to fuel up. I always turn the key to the on position and wait a second or two before cranking, and when I do that, I can usually hear the fuel pump. It's when I don't hear the fuel pump that I know it won't start, and sure enough, crank and no start. My question is, is the fuel pump going out? Or another thought I had was maybe the inertia switch starting to fail? It runs great when it starts, just has a problem starting sometimes.
View 8 RepliesI have a 2000 Ford Explorer with 4.0 SOHC engine, I have had some cold start problems. I cleaned the IAC and the problem went away for a few months and then came back. Two days ago the temps got very cold and it would not start at all, I re-cleaned the IAC and still no start. I replaced the fuel pump with an aftermarket pump and engine started right away. Now I have a rough idle, bad skip and bad exhaust odor. I am still thinking IAC but I am concerned that the aftermarket fuel pump is pumping to high pressure or that I may have crimped the return line. I have driven about 30 miles hoping the computer would make adjustments, still runs rough and the check engine light has not come on.
View 12 RepliesI have a 2013 f150 & the fuel pump relay fuse burnt out. I unhooked the battery cable "wasn't thinking" & took the fuse out & replaced it. Now my truck wont get over 3000 rpms & is driving like i got bad fuel or something. & now its throwing codes about my trac & I don't know why. Just from unhooking the battery cable & hooking it back up. What it is??
View 7 RepliesMy vehicle would not turn over and we could tell it was fuel related. The fiel pump relay has burnt through the motherboard of the fusebox. It is my understanding that this cannot be fixedand another fusebox must be installed. I have been to many junkyards in my are looking for it to avoid the dealer prices..all of the expeditions that we have found locally have already had the fusebox pulled. Any other vehicles that this might be interchangable with? My friend has an 01 expedition..would this work?
View 1 RepliesI have a 03 explorer sport trac that has no fuel pressure the pump will not run. It is a bew pump just replaced it amd drove 4 miles cut it off filled up with gas now it wont run I replaced the pump again thinking I might have got a bad pump but it still wont run. I've checked the relay and inertia switch I have the 5 pin connector on the fuel pump module. 1 wire has good power to it but the pump won't run...
View 6 RepliesI 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)...
View 11 RepliesJust did a complete engine rebuild on 2003 Explorer. All back together....have new battery, starter working, spark at plugs lol crank but no start. Next check is fuel. Fuel pump WAS working fine when timing chain guides went about a year ago...(had to rehab 2 parents and finish bath remodel before pulling engine) So... 1 year later I can't seem to get the fuel pump to work. I checked all fuses and relay. The fuel gauge is working - full tank.
View 14 RepliesI'm working on one of our fleet vehicles here, a 1995 Explorer. about 2 months back, it stalled out. Got it back to the shop and turned the key on .... I couldn't hear the fuel pump. I replaced the fuel pump and the fuel pump relay. Vehicle started right up and seemed to run O.K. About 2 weeks ago, it stalled out again, same symptoms, acts like it runs out of gas and can't hear fuel pump.So, I have been playing with it and find that it starts up great in the cool mornings. In the afternoon when the temps are hotter, it won't start (can't hear fuel pump). The following morning when temps are cool, it will start right up and can hear the fuel pump. I almost wrote this one off as a defective fuel pump, but I'm not sure on this one.
View 7 RepliesI have an 03 Explorer that had a starting issue. Long story short, it had no fuel pressure. So after testing the relay, I switched out the pump with an Airtex unit . All seemed fine...for a while.
Became hard to start again, checked Schrader valve with the key on, and not running, no pressure. Strange though, it would run.
So got the fuel pressure gauge on it. Turn the key and pressure will go to about 5-10psi and then drop to zero. Turn key off and on again, up to 5-10psi, then drop to zero. Turn the key to start and pressure goes up to 10psi, then starts, then goes to 30 while running and you can drive it around. Shut off motor and pressure goes down to zero.how the sending unit is supposed to hold fuel pressure and not release it? Is there some kind of check valve in the sending unit assembly that can be cleaned or does it need a whole sending unit with another pump? I already spent the $100 for the pump, and it is working if you can drive it!
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 have an 04 Ford Explorer XLT 4.0 Flex Fuel. There has been loss of power to fuel pump. Relay and fuse both good, replaced the inertia switch...still nothing. Could a FPDM (fuel pump driver module) have anything to do with this issue? Or what should I check next? I am definitely at a loss as to what the issue could be! I know it is fuel related because I used starting fluid and it started right up and run for just a few seconds, so that should rule out ignition I think.
View 3 RepliesSometimes after running my 94 Limited, it doesn't want to start - it does crank - like it's not getting fuel. I have found the work around and want to know if it would be fixed by replacing the fuel pump relay.
The symptom is just after starting, it starts to run poorly, and then dies out, then will not start at all. I use to keep trying to start it for 20-40 minutes and suddenly it seemed to work.
It seems the work around is to turn the key to on for about 5 seconds and then turn it off - then it starts and runs as good as ever.
So, is this a symptom of a bad relay? I thought I'd start there because of the cost of the relay is fairly cheap. 1994 Explorer Limited 4x4?
The other day, my father-in-law was driving my '91 Explorer and it just died on him. I assumed that the fuel pump quit becuase it wouldn't come on when the switch was turned on. I had a brand new lying around so I dropped the tank and put it in but it still won't work. I checked the inertia switch and it wasn't tripped. There is no power coming to the new pump at all. When the switch is turned on, there is a noticeable "click" inside the engine bay. Would that be the fuel pump relay making that "click"?
View 7 Replies 93 explorer 215000 miles on it runs like a champ 99.9% of the time. I am on my way home today on the highway going 75mph when all of sudden it started slowing down and sputtering. I quickly pulled over and as I did the car shut off. When I was pumping the pedal nothing would happen. I initially thought fuel pump is dead as I dont know if its been replaced. 45 minutes later on the side of the highway after multiple times trying to start, it does and I cruise the next 20 miles home no problems at all????
Got home started it a few times, NO PROBLEMS!
My '97 Explorer is struggling to take on fuel at fuel fill. Started all of a sudden...At gas station last week I inserted nozzle and attempted to fill tank as I normally do. It would not accept fuel at a fast pace. It keeps clicking the gas pump trigger off. I keep squeezing and it keep clicking of every 1-2 seconds!! What can this be? What steps can I take to analyze before I start replacing parts at random?
View 9 RepliesA friend of mine have a 94' Explorer with the 4.0 v6. Fuel pump starts for 2-3 sec when i turn the key, stops when cranking and starts again when i stop cranking. i checked the fuel shutoff switch and it was ok, and it have spark.
View 3 Replies1995 Ford Explorer, 4 ltr. engine, pushrod. Will not start. Replaced fuel pump, fuel filter, every relay, pressure regulator, and the crank position sensor. I realize there's a whole bunch more parts under the hood, but I am ready to give up. Before the fuel pump would not run. Reason for replacing the parts. Now it won't stop running and you can feel the fuel by-passing at the pressure regulator. When checking the pressure at the rail I get zero !! I used a tire pressure tester for this. And, like I said no pressure. This vehicle has around 170,000 miles on it.
View 8 RepliesLooking for a link to the fuel pump wiring for a 2000 V10 Ex? I'm trying to pinpoint my no start issue and want to make sure I don't miss anything. I think it goes from 20 amp fuse under hood to inertia switch to relay under hood to pump? 20 amp fuse has power but at the inertia switch I have no voltage, just approx 35 ohms resistance to ground on both outside wires. Does the inertia switch close a ground or should it have voltage?

View 14 RepliesI have had my car since it rolled out of the plant. Along with other issues one of the most bothersome is a strange smell when I accelerate above 60 mph and it gets worse between 70 and 80mph. Additionally, when I pull into my garage after having smelled this smell on the freeway, I can smell it on the outside of my car.
My car has been in and out of the Ford dealership every month for many issues but this particular issue each time I bring it in. It wasn't until my most recent visit that they told me that with new cars one can occasionally smell this when undertaking a hard acceleration. Then I was asked if I have visited websites or asked questions on the web about this smell. But until now I didn't know what the smell was.
I have been on websites that say this is normal for new cars but if the smell gets worse over time there is a problem with the carburetor. I need to know exactly what to tell the Ford dealership when I go in again have them fix this problem. I also would like to know if this smell I smell is harmful to my children and I. And is it leaking the smell all the time but it is just over a certain MPH that I can smell it.
