Ford F-150 - 1997-2003 :: Battery Light On Intermittently - Ground Location?
F250 LD 99. Battery light flashing from time to time. When it happen voltage gauge in dash go up (but not in red zone so far). All other light are blinking too but not on and of like battery warning light then like stronger - weaker. So far at Internet is said should be ground. I saw one ground at firewall close to negative post of battery but where is other ground? Can it be voltage regulator (alternator)? Did clean battery posts, didn’t work. 4,6 engine. Voltage at battery posts with engine on is 14,7 - 15,1 V. With engine off 12,3 V.
Didn't managed to check voltage when is battery light flashing as it only happen when I drive not at idle.
Ford F-150 - 1997-2003 :: Battery Indicator Light On Dash Started Blinking Intermittently
Just bought my first F150. 1998 XLT 4.6l automatic. 126K miles, looks like it was mostly garage kept. All power, A/C, etc.
Picked it up this evening, drove it home after dark. About a 30 mile mostly highway speed drive. Everything went fine, no problems, no hiccups......Until I turned on my last street, about a half mile from home. The battery indicator light on the dash started blinking intermittently. I didn't notice anything else, just the red battery shaped light blinking.
What would cause this, what should I check? I don't want a big problem when I haven't even transferred the title yet!
Buick - Century :: 2003 - Draining Battery In Night?
2003 Buick Century draining fully charged battery overnight. Have tried almost everything and cant figure it out. The high blower is not working either and I am wondering if a short in that can cause the battery to drain? Changed fuses, alternator, searched for shorts, an so on. Cannot find location of the blower.

Alternator locked up in a parking lot. Replaced it and had to replace pigtail due to a loose wire in the harness. Now battery light comes on intermittently. New alternator is doing fine producing anywhere from 13.9v to. 14.4v. No output voltage correlation to battery light at all. The belt is still in great shape so I don't suspect slipping. Fortunately I caught the old one locking up almost immediately and had recently replaced the belt. Output voltage looks great. Are there any fuses for alternator?
Only thing I can think of that I did...when splicing in the pigtail that connects to the alternator, I briefly grounded whatever wire in the pigtail is hot. Was just a split second, but enough to see a spark and maybe enough to blow a fuse? I've seen people reference an "under hood" fuse box, but I don't seem to have one. My truck is a 2002 CC with just over 100k on the clock.
Ford Super Duty (1999-2016) :: 2003 F250 - Battery Light Came On Intermittently?
I have a 2003 f250 super duty with a v10
i was towing a trailer up and down lots of hills and the battery light on the dash came on. there was no effect on the performance right away. as i kept driving into town i was starting to worry if i would make it.
as i pulled into the carls jr parking lot, the ABS light came on, all the gauges shut off and the truck died just as i pulled into a parking spot.
i figured it was the alternator, had it tested at AutoZone (failed twice) so i swapped it out for a lifetime warranty AutoZone one (very small town, nothing other than an AutoZone)
the truck started after being jumped but the battery light was still on. i figured that the bad alternator killed the battery. the battery was 4 years old and they usually only last 3 years in the AZ heat so i bought a new duralast gold.
the battery light was STILL on after that. the Autozone guy ran his test--- engine off- battery tested fine starting---he said something was wrong with the starter (but it cranked awesomely!) running--alternator tested fine
i just can figure out why when i drive down the road i dash light will turn on and off at random times. the truck seems to run fine. I've even been under the hood shaking the wire while i had someone watching the dash and i cant seem to make the light go on or off
Ford F-150 - 1997-2003 :: 1998 - A/C Work Intermittently?
1998 F150 XLT 4x4 4.6L Auto.
Bought this truck two months ago, the lot had the engine rebuilt due to bad bearings, so fresh motor. They forgot to recharge the AC, so I had them charge it when I purchased it. It blew icy cold every things until a few weeks ago. It wouldn't work, then randomly it would, then it would quit, etc. Today it's 97 and I had it on with my kids in the truck, hot air.
I tried turning it off and on, still hot.
I tried seeing if the temperature was stuck and moved it to hot, it got sweltering hot, back to cold, just warm air. There is no difference between vent and max AC.
I went to the store, picked up a refrigerant filler with gauge and a can of R-134. I hooked it to the low end of the system and was surprised that my pressure was about 60PSI. Great, they over filled it at the dealership. I released the pressure down to 40psi and checked, sill hot. I figured maybe something was weird and they might have mixed good refrigerant with bad and that's why it was intermittent.
I released all the pressure down to 0 PSI. I then put on the can of R-134 and filled it to spec. Sill hot air. I removed the harness from the pressure switch and jumped it, getting sparks when I connect the wire, so it's connecting, but still hot air, probably not the switch.
What's going on here? Could they have over filled it and killed the system or something? What is likely broken here? My heater works like a champ, my AC just blows environment temperature air.
Ford F-150 - 1997-2003 :: Cranks - Won't Start Intermittently?
Several months ago, my truck begins having starting issues. Intermittently, the truck will not start, even though it cranks fine. I have done the following:
- checked inertia fuel switch. Okay.
- checked connections under hood for corrosion. Okay.
- checked fuses & start relay. Also swapped relays with no luck fixing the problem.
- sprayed water at various locations under the hood and bed, since the problem occurs more often when raining. No luck stressing the problem.
- changed fuel filter a couple weeks ago. No luck fixing the problem.
- changed battery over the winter (due to my 8 year old battery was becoming weak). No luck fixing the intermittent starting problem.
- changed the starter a month ago (since the truck stopped cranking). No luck fixing the intermittent starting problem.
- Installed a fuel pressure gauge on the fuel rail.
- Tried banging on the fuel tank with a rubber mallet. No luck fixing the intermittent starting issue.
When the truck refuses to start, the fuel pressure reads 0. Sometimes I can wait 5-10 minutes, and it will start. The truck runs fine after starting.
Sometimes waiting 5-10 minutes will not solve the problem (fuel pressure remains 0). Then, I hook my battery charger to the battery, and the voltage climbs from ~12.5V to 14.7V. The fuel pressure climbs to 30, and the truck starts.
I'm apprehensive to change the fuel pump, since it seems like more an electrical problem than a pump problem. Any diagnostic test that will tell the true problem source?
Ford F-150 - 1997-2003 :: 2000 - Odometer Has Been Going On And Off Intermittently
200 F150 5.4L Triton, 164K rounds. My odometer has been going on and off intermittently since I bought the truck 4 months ago, no big deal. This morning, though, I started the truck to go to work and my oil pressure gauge was at zero. There wasn't any noise coming from the motor aside from the very slight bottom end knock it had when I bought it, so I figured it's the sending unit. I shut the truck off and started it back up a few times to be sure, and the oil pressure sending unit started working. But THEN my 4X4 engaged. The dial on the dash was in the 2WD position, but the 4X4 was definitely engaged. It wouldn't engage when I first bought the truck without swapping the vacuum hoses under the hood, and now it's doing it on its' own.

Own a 1997 F-150, 4.6 L, 4 x 4. I know it's old but it's in very good body shape, has been undercoated for years. I've only had it for a year. This summer it began to not start (intermittently). The dash lights all come on but the starter will not engage. Brought to my local garage, he changed the starter and the ground cable from the battery.
Was ok for a few months and now it's beginning to do the same thing. Brought it back to him, can't find anything. He did say that the battery is a bit weak, the terminals are spotless (I keep them spotless, coat them with white grease). I measured the voltage with the engine stopped and with it running. Stopped, the voltage is 11.94, running it is 14.87. This clearly shows that the battery is weak.
My question is would this cause the starter to not engage after 4 or 5 turns of the key and then on the 6th try, the starter turns over? I don't want to spend more money ($ 450) the last time and have the same result. If it's possible it's the battery, I'll replace it no problem.
Ford Super Duty (1999-2016) :: Radio On By Itself - Battery Draining Severely?

2002 Exc, 7.3L TD, Some one broke into the truck last week by jaming a screwdriver into the door key lock. Tried to pull the ignition out but failed. Pulled the A/V system out, cutting wires and such. So the dealer (insurance covered it ) installed the new door lock and said nothing is wrong with the ignition. But now the dome lights and running board lights come on at random and kill the batteries.
Could it be the ignition? Or something inside the driver's door? The batteries are brand new.
Ford F-150 - 1997-2003 :: Brake Pedal Intermittently Goes To Floor
The brake pedal intermittently goes to the floor on my nephew's 2003 F150 without grabbing at all. Pumping the brakes restores them, then they act normally for a while. I've replaced the master cylinder with a new Motorcraft unit, no change. No ABS codes. All rubber lines are in good shape. I'm stumped, although I suspect the ABS system somehow. I'm going to have him pull the ABS fuse and see if the problem goes away.

My dads f150 shuts off intermittently while driving it. He has to pull over and wait about 5 minutes until it restarts again. We have tried replacing the fuel filter, still shuts off! Some one pointed out the coil!? I am thinking that it might be the switch. It might be bad, shorting out and shutting down the truck?
View 6 RepliesFord F-150 - 1997-2003 :: Idling Rough And Die While Slow Down Intermittently?
My 03 with a 5.4 has been hesitating a when you accelerate and cutting out as well as idling rough and die when you slow down. It does all this intermittently. Not every stop or every time you accelerate. I first got a code for the MAF and both banks running rich (PO102, PO172, PO175) so I cleaned the throttle body and MAF. The running rich code came back (PO172, PO175) so I then changed the MAF and air filter . It seemed to work for a day or so then my light came on and I figured the same code was back but to my surprise it was now both banks running lean(PO171, PO174) so I took my MAF back and got another one. It hasn't set a code yet but it is still running poorly. I have changed all the COP's and plugs as well ....
View 13 RepliesFord F-150 - 1997-2003 :: On Startup Ticking Noise Intermittently?
So on a cold start I keep hearing this ticking noise. Not every time, but more often than not.
I have two thoughts:
1) Low oil pressure causing timing chain tensioners to allow slack in the timing chain. Oil pressure builds up after about 1 minute of driving.
2) Oil Restricter in the valve cover starving one side of the valve cover?
Ford F-150 - 1997-2003 :: 2001 - Cranks Intermittently But Not Starting
I have a 2001 F150 XL, 2WD, 4.2L, Auto at work. It will intermittently crank but not start, also, my scan tool will sometimes not connect to the truck. The only code I ever get is 1 about not being able to connect to self diagnostics. I have narrowed it down to the PCM relay in the underhood power distribution module not turning on because it SOMETIMES only sees a 2 volt turn on signal instead of 12 volts. I have replaced the ignition switch on the steering column- initially I thought that took care of it.
But as I was about to put the meter away it did it again. If I remove and reinstall the diode that is in the PDM, sometimes more than once, I can get it to turn on. Are these diodes available from any one besides Ford? The wiring diagram in my Haynes manual is very generic and does not show the circuit from the ignition switch to the fuse box. Where can I find a GOOD and complete wiring diagram for free on the net so I can print it out and take it with me to work?

View 1 RepliesFord F-150 - 1997-2003 :: 2001 - Oil Pressure Gauge Dropping To Zero Intermittently?
Just recently got a sweet deal on an 01 Lariat with a very low mileage 5.4L. I almost didn't purchase it because the oil pressure gauge will not read when you start the engine. Sometimes it will sometimes not.
When it does read, it is just past half which is the normal reading. When it doesn't read, it shows zero and the light is on. The engine runs fine either way, and the previous owner said it has been that way for years. The engine has been well cared for, and has been running Mobile 1 full synthetic for most of the 80k miles. The oil was not overly dirty at purchase, so I figured it to be a loose connection. I suffer from the cold solder joints that these trucks are plaqued with, as evident by the intermittent odometer reading. Do you think the oil gauge issue is the same thing? A cold solder joint? Or should i just start with a new sender?
