Fuel pump does not work in Cold Weather, but works fine in warm weather? Will replacing the pump solve this or is there a bad sensor somewhere else causing the problem?
View 14 RepliesI have inherited a 1992 Ford Ranger 4.0 with an unusual problem. When the temp drops outside the truck will not crank. The relay is coming on for a sec or 2 to bring the system up to pressure but the pump never turns on. This happens every time the outside temp drops below 60. I can wait until later in the day or until a warm day, hit the key and drive it till it runs out of gas. A week later (and another cold front) and it is sitting dead in the front yard. I have traced the grounds, checked the power thru the relay (and replaced the relay too), but it still does this. What I want to know is am I the only one to ever run into this and if not then what is causing it. Pump shows no sings of trouble on a 70 degree day, even runs the proper pressure and volumes. I am stumped at this point and I am ready to try replacing the pump (though the one in it looks brand new). comments?
View 11 RepliesI have been through 7 fuel pumps in the last 9 months. I purchased the car 1 1/2 years ago with 95000mi from an elderly lady, pulled the car fax and it had no issues and had been back to the dealer every 3000 for every scheduled maintenance and minor routine maintenance. It is a 2001 SES DOHC 24valve.
9 months ago, the fuel pump died right next to the Ford dealer. It had been randomly quitting on me after I would shut it off for a month or so. Then I would hear it priming and knew it would start. Finally, it just wouldn't start after an hour of trying. Of course, the next morning it did.
Took it to Ford, and it wouldn't do it for them, but they thought it sounded like a fuel pump problem. The next 3 pumps they put in wouldn't register a full tank and would indicate that I was low on gas about 50-60 miles before it should, and when filling it, would only take 12 gallons of gas in the 18 gal tank.
The dealer checked the amount left in the tank and verified that it was an 18 gal tank ( which I already knew) when changing to #4 and finally agreed with me that something was amiss. They thought that maybe # 4 would be better because it came from a different place in a different box. These were all supposed to be genuine motorcraft parts.
The next 4 pumps registered a full tank and I was getting about 300 miles before the check fuel light would come on and would take 15.5-16 gal of gas to fill, which was normal. The problem was that they all died after about 600-700 miles. The dealer said they talked to Ford and they kept telling them the same things to check which they did and were all okay. Things like resistance connections. The last pump #7 failed early in the day and still wouldn't start the next day, but did start after getting it towed to Ford. The dealer attempted to order #8, but Ford had put a hold on all the pumps they had in stock. So either they weren't shipping anymore for me or there was a much widespread problem. They installed a Carquest pump this time. This one doesn't register the right fuel in it either. Not as bad as 1-3, but I am getting about 35-40 miles less than I should before the check fuel light comes on and it is taking about 14 gal to fill.
What Ford may be missing when they change these out that I might pass on? They probably wouldn't listen anyway as it took the first 3 before they actually measured the fuel still in the tank even though I had been telling them it wasn't right.
If # 8 works, should I just live with it not showing a full tank, at least it is working. Either way I am afraid to drive the car to anywhere but work and even that is kind of nerve wracking.
At least the pump has been under warranty every time to I get a loaner and they fix for free, but I want it fixed right!
Having a problem with the fuel pump engaging. Warm or cold same problem. When I turn the ignition on I can hear the fuel pump engage and the car runs fine on start. Other times I turn the ignition on and don't hear the pump engage, thus no start. But repeatedly turning the ignition on an off I get the fuel pump to engage and I have start, will run until I shut it down. been doing this for a couple of weeks now. Is this an ignition thing or fuel pump? No wiring diagram. Replaced all relays, battery good. Never did anything with the fuel system.
View 3 RepliesI have a 1997 geo prizm that locks up the power steering pump mostly in cold weather until the car warms up. It does it itermittenly. What could cause this problem?
View 2 RepliesI have a 2000 Nissan Altima that works great except when the weather becomes cold in the winter. The brakes don't work when I turn on my car. The brake lever will not press down at all and once or twice (before I realized this was happening) my car went sliding down the road without an ability to stop. I can't tell if they start working after the car warms up or after I've pumped them for a while because they'll start working again at random times. Sometimes it takes a few seconds and sometimes it takes a few minutes.
View 15 RepliesMy wife's 2007 Prius Dash lights stop working in extreme cold weather. We have asked the dealer 3 times about it but to no avail! I don't even know where to start with this one?
View 2 RepliesDuring this week, most ppl at NA are experienced extremely cold weather, what I found is, the Prius can't do a great job to keep the front windshield clean under that kind of condition.
What I tried, front deforest bottom, or fan to front windshield and leg, both works fine for the middle area but not the top left side which is about 1/4 area of the windshield. It doesn't happen on my sienna. Usually I drive 5-10mins and the windshield are clean. What I guess is maybe the fan tunnel goes too straight to the windshield instead of blow to the rear area or maybe the outlet isn't wide enough to cover the side.
I own a 2007 Ford Taurus with about 108k miles on it. When I first start the car, the rpms stay very high (2000) or so for about25 seconds. Once I start the car, until it gets all the way warm, the rpms want to stick around 1300 until I'm stopped for a few seconds, then they jerk downwards hard to almost 400 and come up to around 700.
After the car gets warmed up, it no longer sticks when I brake, but then when I'm stopped it lurches shakes and jerks between 400 and 1000 rpms. Occasionally it will die ( maybe twice a week) but then starts right back up again. I have replaced:
Air compressor
Idle air control valve
Throttle body sensor
I replaced the throttle body sensor yesterday and it seemed to drive better but it only lasted for about 12 hours then the next time I started the car it's doing it again. The only solution I've found so far is that it jerks just a little less when I'm in neutral.
Having problem with an exhaust or fuel smell in the cab? i have had the exhaust checked & the seal on the back door, all have been fine. it has only happened in the really, really cold weather.
View 30 RepliesUsing fuel additive with V10's in extremely cold weather? If so what are you using?
View 4 RepliesI've got a strange problem on my '01 F-150 4.6L 4X4. When the outside temperature gets below 40-45 degrees the fuel pump won't always run when trying to start the truck. You can cycle the key switch on/off 8-10 times and the fuel pump will run. The engine will then start and run fine. You probably have to use this procedure 80% of the time. It started this last winter. I replaced the fuel pump relay in the power distribution box under the hood but that did not work. When the outside temp warms up the problem goes away.
View 10 RepliesFirst, it's not a sticky IAC. I already experience that in cold weather and compensate simply with the gas pedal until engine warms up. However this coughing, sputtering, backfiring, misfiring problem is very severe. When it is in this state, the engine will lose rpm and stall. No way to coax it with the gas pedal to keep it running.
It happens most often when you restart the engine after having stopped somewhere for 10-30 minutes. It happens less often during a cold start in the morning. When it does this, I remove the key, and try again. Usually in 3-10 tries, the engine runs properly. Once running properly, there is never an occurrence of this.
However, today only, first cold start, it cranked and would not fire at all. Repeatedly. Jiggled the key and maybe they made it start. Ignition switch? If Neutral Switch, it should not have cranked. Perhaps my intermittent problem is worsening.
Wet weather seems to aggravate it.
I have a 2000 Corolla CE with 51k miles (bought a couple of months ago).
It ran perfectly during the hot weather (75-80F) and it idles around 650rpm-670rpm. These couple of weeks, there have been very cold weather (60-70F) and it idles mostly around 650rpm but can drop to 630-640rpm. Sometimes, it will suddenly drop to around 612rpm (there will be a very slight shudder) and pick back up to 630rpm. This is with all accessories turned off.
If I turn on the windshield wiper, then every time it activates, it drops to around 612rpm and picks back up quickly. This only happens during cold weather.
I don't think it's the MAF sensor.. what it could be?
Title pretty much says it. When its COLD it surges while idling upon start up. It goes away once you start driving it and the engine warms up. Other than that it runs great. Its got about 235 K with a replacement motor that has about 100k. I've had it about a year. Great vehicle. Its a standard.
View 2 RepliesI am writing this about my fiances 2000 Oldsmobile Alero 3.4 liter. I live in MN so we see our fair share of cold weather. After her car has sat over night it will not start in the morning when the temp is below 32F or so. It started happening at the end of last winter and then it got warmer out and the car became normal...which is hard to figure out the issue when you cant verify the problem when you want to. Anyways we just had one of our first pretty cold nights and we went out to start her car and it barely started.
I have suspected it to be a fuel issue because while trying to start it if I hold the gas pedal in it will start to backfire lately and just acts like it is flooded. This last summer I looked over some things and found that the Fuel Pressure Regulator was leaking into the vacuum line which would go into the intake manifold and flood the car. So I replaced that convinced that it would solve the issue. It didn't. I also found that the PCV valve was stuck so I replaced that. Last winter I dumped in a bottle of gasoline de-icer or whatever that stuff is called thinking maybe she got some bad gas and her lines were freezing. That didnt change anything.
When the car wont start I can literally crank until the battery is dead (newer battery in the car) with no luck. I have had to be jumping it and cranking it over for a good hour to get it to start. Not cranking straight time obviously. But about an hour worth of time before it starts. And at that time i am thinking it starts just because of the air temp going up in that amount of time or something... I don't know. I am not quite ready to bring the car into the shop because I know it will need to stay there for a few days to be able to get the right conditions for them to verify the problem. My fiance and me have very busy schedules between both working full time and going to school full time. So to be without a car for a few times isn't an option.
2000 Sierra 1500, 5.3L engine. When he starts it in the cold (below 40 degrees) at first hits 1000rpm, then immediately drops to 400-500rpm. The idle is rough and wants to die if he tries to drive it. However after 10-15 minutes and the eng warms up, its fine no problems at all. There is no codes, so the scanner we had didn't tell us anything. He had cleaned the TB and intake system with cleaner, no dice. He also disconnected the IAC while it was idling rough, that didn't change the way it ran at all. We would like to toubleshoot it more before we start throwing parts at it.
View 1 RepliesMy 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 RepliesSo my wife drove her car all day yesterday, everything fine. This morning went to start and it wouldn't. It turns over fine just not firing.
Now during the summer I had replace the fuel pump/filter before discovering that was not the issue.
I know you are already thinking CPS!.. I replaced that over the summer.
I have not checked the spark yet, kinda hard to do that one by yourself.
Beyond spark I am not sure what else could be wrong, especially because it was running fine last night. Is it common for accents to have issues in 20 degree weather?
Radio is fine, all gauges and such seem to be normal. The climate control unit displays 75 degrees, the fan is blowing, but none of the controls do a darn thing. I can't turn it off, up, down, or anything. Where to start looking?
