Ford 7.3L Power Stroke (1999-2003) :: Both Headlights Suddenly Stopped Working
Jun 16, 2010
Well a few days ago I pulled up to a gas station on my way to work for some coffee and since I leave for work before 6:30 AM my headlights were on. Well only the running lights were working. Well I shrug it off and later that night I come to the realization that both headlights weren't working. I tried the high beams and they do work. I also pulled both bulbs and both the filaments on each bulb seemed to be intact. What could cause this? I checked fuses 9 and 11 under the hood and they were both fine. I'm kinda at a loss right now.

so all of a sudden I put my blinker on and it was flashing fast. My first response was to check if a bulb is out, not the case. Five minutes down the road my brake lights stopped working and the 3rd brake light stays on.. when I put a blinker on the rear lights and 3rd brake light and the lisence plate plate lights all flash at once.

I was driving from my house the other day when the engine suddenly cut out and the dash went blank. there was no warning, it was like someone pulled the plug.
-When I turn the key to the first position (Acc) all the accessories work as normal. the lights, radio, windows, ect all work like normal.
-When I turn the key to the second position (run) nothing changes. no gauges, no dash lights, warning lights, and no (wait to start) squiggly line. only thing I hear is the high pressure pump on the engine cycle.
In the third position (start) the truck will turn over but will not start.

Recently my power windows stopped working...sort of. Here's what I mean: If the drivers door is closed none of the windows will go down. However, if I open the drivers door halfway or all the way I can roll up/down all the windows. If the windows are down and the drivers door is closed I can, almost always, roll up the drivers window, however the other windows in the truck will usually not roll up. Open the door halfway and up they go.
A couple of other things I have noticed. When I press the down button for the drivers door window, with the door closed, I can hear the relay, under the dash, kick on and the window will move about a millimeter down then stop. Additionally, the courtesy light on the drivers door comes on while the door is closed. I haven't checked if the other courtesy lights come on at the same time.
Hopefully my explanation is understandable. I would love to solve this issue. Getting tired of opening the door to roll down the windows. Plus when there's a fly in the truck and I'm driving I can't get it out.

Cruise just stopped working. The fuses all check out ok. What would be the next simplest thing that I could check before turning the problem over to a mechanic?

I have a 2003 CC f350 6.0. I am having some ac problems. I replaced the Compressor , dryer , orifice tube and condenser I pulled vacuum and charged to proper level. I did all this about 3 weeks ago. Was blowing 38 out of center vent driving down the high way. Ambient temp about 100.
OK now for the problem. Yesterday I was at the parts store truck running. AC was cold when i got there. Blowing hot air as i left. Never got cold compressor never kicked back in. I put gauges on it this afternoon High/low pressures where about 10lbs over ambient temp (Engine off)
Ac will not engage at all. Jumped low side cut out nothing. Replaced ac relay old one tested bad still no ac. I can supply 12V manually to the clutch with my power probe and ac kicks on and work great. There is no voltage at the ac clutch connector. I am at a loss on this.
There is power 12V at the low pressure cut out pigtail. There is 12V on 2 of the high side pressure cut out pins. But no voltage at the ac clutch. You can feel the new AC relay engaging whenever the ac is turned on (engine running).

Here's the story. Truck has showed no signs of rough running. Wife drives truck around town. Truck up to temperature and doing fine on a 90 degree day. Stops at red light. Makes left turn engine light comes on truck seems to be running on 4 cylinders. Pulls over light goes off engine idles perfect. Pulls back on road light on no power. Gets truck to a local friends house lets it sit til I get off work.
I check for codes get p1316. Drive truck toward my house no problems for 4-5 miles then does the above with me. Limp it home. I know it is pointing at a wire problem to injectors and or IDM. Did a buzz test passed fine. Plan on pulling valve covers and looking for the usuall things. Any thing I am missing? What will a kOEO test tell me? Should I run one? How common is IDM to go out? One last thing just put a rebuilt transmission in it 3 days ago may be unrelated it seems to be doing fine.
2003 f-350 cc 7.3.

I was driving today and all of the sudden the dash went dark. No odometer, power windows, radio nothing. As soon as I touched the brakes it went dead. Wouldn't restart and all I could hear was a constant buzzing coming from the fuse panel by my knee. Let it sit for five or ten minutes then it would fire up and run good then do it all over again. The second time the truck had no power. I put a jump pack on it and fired right back up. After the the third time I called a toe truck. I'm guessing it is a electrical/charging issue.

Jumped in my truck a bit ago and it wouldn't start, although it is turning over. The "Wait to Start" light is not coming on and the Overdrive button on the shifter is lit up OFF and won't change with me pressing the button. I've checked all the fuses under hood and inside cab with multimeter and everything checks out ok.
Also, when it was raining last week I found that when I turned on my windshield wipers the truck would die. My solution to get home was to just flip it back & forth real quick every so often so I could see out the windshield.

I am a cummins owner who just got a 2002 7.3 last week. It drove great for 200 miles then suddenly died last night going 60 mph. It sat overnight then started up and drove 10 miles then died again. I changed the cps and still no start. I changed the oil and let it sit overnight and it started this morning and idled for 5 minutes then died again. I have tried unplugging the ipc and still same no start situation. I plan to check the hpop level today to verify it is full. I also checked the nut on the ipr and it's electrical connection.
I am just a shade tree at best and would love some direction on where to look. I don't have any scan equipment to check pressures. Am I correct in thinking it is a bad ipr?

Comming back from hunting today my truck suddenly lost power and stepping on the accelearator had no effect at all. We were on the highway thru the mountains but on a fairly level stretch for a few miles. Managed to pull the truck and toy hauler over and the engine was running fine but stepping on the accelerator had no effect. The check engine light came on every time I stepped on the throttle and went out when I released it. It started fine but no throttle response. Switched around a bunch of relays and checked the fuses and still nothing.
Not liking my parking spot i tried to see if it would move down the road at an idle but it would not. Then I thought to try it in 4 wheel low and as the shoulders were soft it wouldn't move forward so tried reverse and went back a foot, forward again and moved a foot and a half. did this several times and all of a sudden the throttle responded, took it out of 4 wheel and it ran fine all the way home. What would have caused this? I was ready to call a tow truck which would have been several hundred dollar bills for where we were and with the trailer

Ok after rebuilding trans and being down a couple of weeks, I went on my 1st run since completing. Noticed when I started truck this morning it didn't turn over as fast as it was. 30 miles down the road Airbag Light comes on, and then volt meter dropped to 8 volts. Got stopped with truck still idling checked everything I had the tools to do so for. Decided to get back to my shop where I had tools, and 5 more miles and 55 mph truck just shuts off. Lost all power, truck would only click. Put my booster box on battery and gauges went back to normal but still wouldn't turn over but maybe once? Only place within a mile of my location was Walmart. Bought 2 new group 65 batteries, installed them and Shazam cranked right up no more problems. Short of the story bad batteries that checked Good with a load tester don't mean squat!

This started about 6 weeks ago. While sitting at a stop light the motor cut out. After some research I replaced the cps. Truck ran fine for about 3 weeks, then shut down again while pulling into the driveway of a store. Replaced the cps again (this time with a ford one). Ran fine for another 3 weeks, then shut down again on the freeway. No CEL on any occasion.
It's just like someone turned the key off. No rough idling at all. No smoke during starting or driving. When it shuts down, it will not start again for 20-30 minutes, no matter how many time you crank it. It will just turn over, no sputter. When it fires up again there is no air in the lines either, it runs like nothing happened.
I'm now thinking it might be a ipr issue...is there a way I can check myself or does it need to go to the mechanic? Or is it something completely different? This is my mother in laws daily driver, 178k. She does not drive on the freeway, 80% of the mileage is city driving. What could be going on?

Here's the situation - 1999 F350 with the 7.3 PSD, crew cab, auto, 4X4.
The truck runs fine in good weather, but if it's raining or snowing, it will suddenly die - and by that I mean lose all power as though you turned off the key. There's no warning. It lasts for a period of time, and then the truck will restart - most of the time.
It's seems like it should be a pretty simple/obvious electrical problem, but I've had the truck in to two of the best diesel shops in town, and neither has been able to locate the problem, in spite of countless hours and some pretty big bills being racked up.

I have a 99 F450 bucket truck. I was up in the bucket when the engine died suddenly. It turns over but won't fire. I have no dash warning lights now either but everything else seems to be working. Lights, radio, annoying beeping sound from the key left in the ignition, etc. There are roughly 5 or 6 fuses in the panel to the lower left of the steering column that don't have power to them. Are they all supposed to have power when the ignition is on? I checked the fuse panel under the hood and all of the fuses that have 12V to them are good. There are a few small ones that don't have power to them but I don't think they do all the time.

Is there a mod that allows the headlights to stay off when the key is in the on position. 2001 F250....

I have a 2003 F350 SD FWD Dually With 4.10 Axle Ratio. I'm looking for some front rotors and pads and I'm looking for recommendations. I tow a 44' Goose neck racing trailer on a regular basis so I dont want autozone crap rotors that are going to warp in a few thousand miles. I was on rockauto.com, they have Wagner, Bendix, Motocraft, Powerstop, etc etc. I thought maybe those Powerstop drilled and slotted looked interesting, but I dont know much about them.

I own a 1999 F350 CC SRW w/ 7.3L PSD engine. My turn signals stopped working suddenly. I've checked the fuse panel under the dash but it doesn't show any fuse for the turn signals.
My hazards do work although I noticed something very strange. When I tilt the steering column down the hazards stop working and when I tilt the column all the way up they work again. Still no turn signals though.
