'99 Explorer 5.0 doesn't want to start in the cold weather, below 30. After it finally starts it runs great and will start all day. It cranks fast but it doesn't get driven every day.
View 2 RepliesWhen it's cold outside my car will start up, but not stay running. The only way I can get it to stay running is to keep my food on the gas for up to five minutes. Once the vehicle is warmed up, it stays running. If I start it every hour or so, it will run fine. It's just when it's been sitting out in around zero degree weather overnight for example.
View 4 RepliesMy dad has a 99 F250 with a no start issue. Everything was starting and running fine one day. The next he gets a no start. Cranks fast and fine but wont fire up and start. He has a scangaugeII hooked up to it and his oil pressures and volts look fine. His tach moves when he is trying to start it. He checked the icp sensor and it had oil through it so he replaced it with a Ford part. Unplugged it and the scangauge pressure goes up but no start. He also replaced the ipr with a new Ford one just in case. He checked and is getting low pressure and high pressure oil.
I am having him check the fuel heater fuse #22 to make sure it is not blown. He had the block heater plugged in all night along with a battery charger to make sure they are topped off as well. We have gone through a couple of the checklists on this site for a no start condition but nothing has solved it yet. I think he is sitting at about 200k on the motor. No major issues or problems until now. He is currently also pulling the ICM to check it out as well. No codes are being thrown.
The colder it gets the harder it takes to start my 2000 Ford Explorer. Have read that it's the Intake Air Temperature Sensor.

View 4 RepliesI have a 1991 S10 with a 4.3L V6 TBI that recently began having trouble cold starting, meaning that at a mere 40F I can crank it over and over and it will not catch. If I plug the block heater in for at least an hour, it usually will start, but at a very low, very rough idle. Once it has about 30 seconds or so to warm up, it will then idle TOO FAST at 1500 rpm, and stay that way for the first few miles of driving, which makes it rather awkward to drive, being a 5-speed. Once its been driven awhile and fully warmed up, it runs normally. (I'm running a 180F t-stat.)
The IAC valve, block temp sensor, and TPS sensor, were all replaced last year, so I'd find it hard to believe that one of those could be the problem. I put Heet treatment (red bottle) in the fuel, changed fuel filter and reset the computer. (Although it's never given a trouble code.) The problem is still there.
My local mechanic says replace the ECM, but he hasn't actually diagnosed that as the problem, so I think he may just be taking a wild guess. (He hates OBD1 systems with a passion!).
I picked up my 05 F350 dually 5 speed w/ the 6.0 powerstroke motor in august... It only had 38k on it when I bought it... its got 43K miles on it now...
Ran great in the warm weather but ever since it got cold out its been a struggle. It was running rough on the way home and kept stalling while i was driving it.. (acting like it was starving for fuel).
I went and replaced both fuel filters and started the truck... let it warm up and it stalled while sitting in my drive way and haven't been able to start it since...
I have fuel additive in it but since I don't drive it all the time (maybe 3 times a week for 30 miles) could it be possible that the fuel is gelling?
I was going to check the EGR valve tonight...
I have the LED mod and several weeks ago, my LED stopped indicating and the truck would not start in cold weather unless I jumped the terminal on the relay. I replaced the relay and while I was tightening one of the small lugs, the one towards the nose of the truck, I felt it break.
The truck acted just like it had been for the weeks prior, if I didn't jump the relay, it wouldn't cold start, so I assumed, because I had broken that small lug, it wasn't getting the signal to turn them on.
So what now? obviously the GP's themselves are working, as the truck starts when I jump them. But for some reason no signal is getting to the relay. What do I need to check to see what is going on between the PCM and the relay?
01 F150. Cranks but no start, will fire with starter fluid spray. Theft light fast flash, Check engine light on. Only have one key and don't know what the kid that had owned has done.
View 5 RepliesI have a 1998 Ford Explorer. 215K miles. Original Owner. When it is cold there is a very light leaking of brake fluid at the base of the master cylinder where it meets the brake booster. This morning it was 14 degrees and there was a much bigger leak. Filled it back up and went to work. I'm thinking its about time I took care of it. I've had the the master cylinder replaced once at Goodyear Auto Service Center years ago.
I'll post a picture later but having the leak where it is. Would that be a replacement of both the master cylinder and brake booster? How can you tell? Or is it better just to change out both. Having done more work on my car over years I feel I can do the work myself. Plus the master cylinder is only like $50 and $60 for the brake booster.
I am having trouble getting my 2000 7.3 (200k) to start on the colder mornings. It will crank over fast, but won't start without a lot of tries. Today it took 6 pre-heats and cranks, but on others (and colder days) it has started easier. It does seem to be getting worse though.
I have replaced the glow plug relay recently so it *shouldn't* be that unless the replacement is fried. Starts fine the rest of the day and drives fine, but not in the cooler am (it was about 34 this morning). I also tested the batteries yesterday and while they aren't new, they tested okay.
Also, I read (briefly) about the CPS, but forgot to watch the tach this morning, but did notice it is pushing smoke out when turning over.
I have a 1999 Explorer with a 4.0 engine and when it gets cold it has trouble starting. It will click for a while and then start, but when it is warm I have no problem starting it.
View 3 RepliesMy 2000 Explorer overheated and I had water pump and intake manifold replaced.. then it had a freeze plug rust out and its replaced, I'm holding water.. but now it just wont start.. we've tried everything from changing fuel injectors, fuel delivery unit on intake, now the fuel pump is changed.. still wont start and the theft light is flashing fast.. my dad changed computers while I was out of town,, is it the theft device or does the computer need coded for this explorer?? we have taken negative off battery but nothing.. And if I change the motor will that work or still not run because of theft light or computer??
View 3 RepliesHow to reset the Anti Theft on my explorer? The light is flashing fast and the engine won't start. Without the anti theft being reset the truck won't start. Been checking around to find an answer but can't find one...
View 7 RepliesI just purchased a 2004 Explorer from a police auction. It had driver side damage but nothing major. When I try to start it it cranks but nothing else. I purchased a new battery, fuel filter, coil packs, spark plugs and installed all. But same thing it tries to fire up but stops short. A few times we sprayed starter fluid in it and it would start for about a second and a half and shut off..... I also listened for the fuel pump and I hear it coming on when I turn the key and checked the inertia switch...
View 9 RepliesParked in driveway and 2 hours later it cranks but will not start. Pushed on fuel rail Schrader valve and it squirts out. Turn key and the fuel pump runs for 2-3 seconds then off...... Thought I had fuel... assume electrical. Read posts last night and thought crank positioner pickup was a good place to look. Took spark plug leads off #1 and #4 at coil and set a 1/4 steel dowel in each so they were 1/2 inch apart. Crank motor and I get spark out of coils so I assume the plugs are getting fire... Took off intake hose and shot ether in the tube while cranking... no fire or pop at all.
Where to now ? Seems like I have fire to the plugs, and fuel available but will not start. I have only one code and that's PO1116 coolant temp out of range..I don't have a cam sensor code or a crank sensor code...I thought they might effect the timing ? With spark at the plug wires, you would think I would get a "POP" now and then, especially with the ether ?
My explorer starts fine some days and others it just wont. No codes, have replaced fuel pump. Rail and starter.

View 3 RepliesI have a 5.0 Explorer 1998 and it has a problem for which I cannot find a definite solution, everyone says a different thing. The problem is that when the weather is hot, sometimes the engine does a strange thing. You ride the car for some time, especially if you do it on a high speed so the engine is really hot (but no overheating symptoms) - and then you kill the engine and leave it for a few minutes - to walk into a store, let's say.
After that you attempt to start the engine... sometimes it starts, but there were several times when it refused to catch, it cranks, at first tries to start, but stalls... then it just cranks without even attempting to start. And I had one occasion when it stopped working right in the middle of the road while crawling in traffic, but it was really HOT outside. Luckily, all other cases were in our town, so I could at least walk home. So, the problem seems to overheating of something, as in normal or cold weather it never happens. And every time, after the car is left to stay in place for some time, an hour or more, cannot say exactly - it starts perfectly!
I am really tried of this and want to eliminate the reason. But I am hearing so many different opinions about this problem. I thought that it could be the overheating of the fuel pump. But then it would stop working while moving, not after you shut the engine off and the pump cannot be still working and overheating. The only place where the heat can build up when you stop and turn the engine off is under the hood, as the fan stops, the coolant pump stops and the air isn't blowing as the car isn't moving. But the pump is in the tank! And I never ride on empty fuel tank, I always keep some level, lately I tried to keep it even higher, but yesterday it refused to start when the tank was almost half-full. Also, if it was just dying - a dying fuel pump gives certain symptoms like slow acceleration, engine shaking and trying to stall when you press the pedal, sudden stalling, uneven idling etc. In this case, nothing like this. The car's behavior is absolutely normal, acceleration good, normal idle. It happens ONLY under certain conditions, involving heat.
Other people say that it can be due to low pressure in the fuel ramp and the gasoline is starting to boil at some moment, when the temperature under the hood rises to a certain point. As a reason they name the pump (but as I said, I doubt it) or the fuel pressure control valve - don't know its exact name, it's a valve which maintains a certain pressure in the fuel ramp and releases excessive pressure by returning some fuel to the tank. However, when this valve gets stuck and doesn't maintain pressure, it mostly influences the cold start, as the fuel pressure drops and you have to crank for a long time while the pump is building the pressure again. But my car has never had any problems with the cold start, it's always instantaneous. Also, when this problem occurs and you start the engine after it cools down, it catches instantly which means THERE IS pressure in the ramp. So I don't believe in low pressure, gasoline boiling and resulting vapor jams.
And finally, I read that it may be caused by defective/dying engine temperature or crankshaft position sensors. As for the temp sensor, I will replace it tomorrow anyway. I am also thinking of having a look at the crankshaft sensor, where it's located on 5.0 V8?
Fast idle 6.7 when cold remote start. My GM had what could be called a auto fast idle when it was cold it idle a lot faster.
It appears my 2012 f350 does not , Ford dealer said he could install a fast idle using one of the switches.
And then if I park truck with park brake on and switch on it when I start it will fast idle to around 1300.
My question is being if truck is started by remote , will not this switch be off and by being off fast idle will not work , is this not the case?
