I have a 2003, F250 SD, 5.0 with a weird problem no one can figure out. Now it doesn't matter what time of the year it is but after the truck sits a few days when I go to start it up it run roughs. Sometimes for a few seconds sometimes a few minutes then it "straightens" itself out. Recently it took almost a day to fix itself. No engine codes, no other symptoms.
View 4 RepliesMy battery on my 2008 SD goes down sometimes after the truck has been setting for a few days. This doesn't happen very often, and I've checked to see if I left something on that could have put a draw on it. I can find nothing that has caused it. I jump it off and might go a month before it happens again. I've got an add-on voltmeter that show voltage when the switch is on, and it's charging perfect. On older trucks, I would simply put a test light between the positive post and the cable and checked for a draw, but on the later model there is always a slight draw to keep memories alive.
View 9 RepliesWithin the last few weeks my super duty battery has been dead after sitting a few days. Draw is around 80 ma. When I pull the air bag fuse it drops to 10 ma. Before I tear in to this thing need to know where to start.
View 3 RepliesHaving problems with a slow drain on batteries? My truck wouldn't start after sitting for 5 days.
After recharging and starting it up once, I pulled the key, and disconnected the battery harness and checked for current on all the red wires in the harness. Only one drew current. I found the small red wire on the drivers side initially draws 470mA for 1 minute, then draws 22mA. In my experience in mobile audio, 22mA can drain a battery over several days.
Has anyone out there checked their 'dark current' draw? I have chased it all over and checked all the aftermarket add-ons and it comes down to something in the factory dash.
I have a F350 with a V10 Triton motor. It has 186,000 miles on it. I have difficulty in starting it after it has sat for a few days. Typically I have to turn the switch off and on multiple times but it will eventually start. Once it has started it runs and starts fine if it has not sat for any long period of time.
I connected a pressure gauge to the schrader valve. Initially when the key was turned on there was no pressure. While the engine was turning over it was about 30 psi. When the engine started it remained at 30 psi. Ran the engine at 4,000 rpm and the pressure remained about 28 psi. Shut the engine off and turned the key back on the pressure showed 20 psi and remained there.
I'm thinking maybe the problem is with the fuel pressure regulator but can seem to find it. I've spent multiple hours searching online for the location of the Pressure Regulator but no luck.
My 2003 F-250 (gas V8) will always start right up when it is cold. However, once it has warmed up, it often will not start. Cranks fine, but not even wanting to start (like someone pulled all the plug wires) and has left me stranded until I wait for 3+ hours for it to cool back down. Doesn't trip the check engine light, but seems to be due to the engine being hot. What this could be?
View 7 RepliesAbout 20 miles into it, and it starts cutting out on me under load, over about 1/4 throttle. I baby it a ways further, and park at a wal-mart. Idles fine, but once again, after 1/4 runs like crap, acts like it's back firing through the intake spit and sputtering. Have the wife come pick me up since I was heading to work. Decided to shut it off, and restart, and it acts like its never had a problem.
Was messing with it today, and let it warm up in the driveway. Once it got hot, same story good 1/4 throttle, past that, not so much. Shut it off, started it back up and drove it to see if there's any codes at vatozone. Drove good (laying into the throttle) for about 2-3 minutes, back to same behavior. Hooked up code reader, no current codes, and no historic codes. Although I did notice (actually since I bought the truck) that the check engine light never comes on, even at initial start up. Looking at my spare cluster, it's an l.e.d. So no bulb out I guess unless the led is bad. Truck has around 130,000 miles on it. Everything is stock.
I'm leaning toward a fuel pump, a clogged cat, or a fuel pump relay or cutoff switch problem.. It doesn't have any other issues than that, and has been a good truck for the 10k miles I've owned it... 2003 F250 5.4...
I have a 2003 F250 with the 5.4 and I believe I am having a fuel delivery issue. I took out yesterday and stopped to get a drink at the gas station, came back out and the truck wouldn't start long enough to idle. It would start, barely bounce off zero rpms and die out. I checked the fuel interia switch and it was down. I tried turning the key back and forth thinking it might reset the fuel pump or something and that didnt work. I get the truck towed home and couldn't get it to start last night. I go out this morning and it starts, come home from work and now it won't. This happened about 2 years ago and I never did anything about it, but it took 2 years for it to happen again.
View 2 RepliesI bought it and changed the fuel filter and it was dirty. Then ran a tank of gas with seafoam and then with lucas fuel injector cleaner. Still nothing. It idles like its missing and as long as you are light on the pedal it revs up fine but if you're heavy on the throttle its. Its has no codes that's why I haven't replaced the coil packs and plugs but they have been ordered. I just thought there would be an engine code if any of the coils or plugs were bad. Looked for a vacuum leak but couldn't find any. The donut gasket on the pass side is bad would that cause it to run shifty with no code.
View 2 RepliesMy truck is a 2003 f250 / 2wd automatic, 7.3 powerstroke, 284000 well maintained miles.
Just last week I sprug a large oil leak and had to replace the hoop outlet o rings..problem solved. This week I can drive 15-20 miles on the freeway and the truck starts to act like ota running out of fuel. Bogs down to 40mph then starts missing. I pull over, and when revving I have un burnt fuel and oil smoking out of my tailpipe. I let it sit for 5-10 minutes and it will be fine for the rest of the drive and this happens intermittently, there is no pattern.
The truck has a ton of power, starts great hot or cold. I did a ton of research and found a IPR could possibly cause this, as could plugged screens in the fuel pickup. Then I read about all the injector harness issues but I don't think that I my issue.
On a 2003 5.4 f-250 XLT 4 door, long bed
Running 285 tires, none lifted, factory lifted for snow plowing? Did have a plow mount when purchased used.
Had the truck over a year now & love it. My only real dislike is the stiff/ rough ride when empty, which is 80-90% of the time for me.
I know my truck & year have leaf springs with shock dampeners on the front, vs the coil spring and shock dampeners that came in the later years for a much improved ride. Also my struts are "Rough Country" which from what I understand are cheaper shocks. Had a 04 Tacoma I replaced with Bilstein 5100 shocks after leveling it & it was an amazing difference. So that's my only real comparison in shocks. I've read of guys replacing their entire front end for the coils & springs. Not interested in going that deep into it for a better ride. If that's my only option, all be happy with the ride as is.
What are my options if any? Better shocks/struts? Other than my rough country that are on the truck? Purchased used a year back & never felt the "stock struts".
I did find Bilstein 5160' s for my model truck. Link : [URL] .....
The 2003 F250 5.4 Superduty has no power and keeps stalling. If I floor the gas it just stalls. I've replaced the pcv valve and line, the fuel pump relay, the fuel pump, and cleaned the tank, changed out the gas, added Lucas, and it just won't run right. Desperate, and no codes are coming up...
View 5 RepliesI am looking at purchasing a 1999 f250 Crew Cab Long bed with the V10. It has 120,000 miles on it and has been very well taken care of and maintained. The current owner says that over the last couple of weeks it has started to start sporadically. The first time it did it was after a 30 minute drive. Parked the truck outside his garage and a hour later when he went to pull it in the garage, it wouldn't start. He called a mechanic friend that told him to trip the inertia switch.
Pressed the switch, it clicked, and then the truck fired right up. Since then it has done it twice more but now instead of tripping the inertia switch he turns the key on and off 10 times and then it starts right up. What this would be? I would normally think fuel pump since cycling the key on and off would be building pressure in the system if the pump was just starting to die but the inertia switch being tripped has me confused.
The owner thinks or was told that quickly turning the key off and on is resetting the computer and after turning the key 8 times the locks lock and unlock and the lights flash once. Is this what it is doing? I thought turning the key on and off in multiple succession let you manually read the codes...
My 1999 F-250 wont start unless I use a squirt of fluid but once started it will run fine could this be my cam sensor or do I have an injector problem.
View 4 RepliesI just recently bought my 2002 F250 Lariat with the 5.4 and 76 thousand miles. I love this truck but I've started to notice a few things with it. When i go to start the truck it sometimes starts but then instantly shuts off. When i try it again it takes a long time to crank over. This has happened in cold and warm weather. What the problem could be and things i could do to prevent it?
View 2 RepliesI have a 2000 Ford-F250, V10, 6.8 liter Gas. The issue is that when I try to start the vehicle it will start, but then start to idle real low and then die. If I try to restart sometime it will and sometimes you have to let it sit. I can also pump the gas and it will sometimes start.
View 6 Replies1999 F250 SD V10 I recently replaced the in-tank fuel pump and filter. I operated the truck briefly after and everything was normal. I parked it with about 1/4 tank of new fuel and put it on a battery tender. It was parked in a garage on level ground in temperate weather(Southern Calif.). Two months later I tried to start it and it acted like it did when the fuel pump was bad. Cranked fine but no hint of starting. Could it be the fuel lines have become full of air and need purging through Schrader valve ? I haven't begun to troubleshoot but what to check other than pushing the fuel relay reset button.
View 5 RepliesMy diesel truck is stuck at work. It cranks but it's not starting up. When I turn the key, the glow plug light takes a lot longer than usual to turn off. When I try to start the truck, it cranks fine and I get a lot of white smoke coming out the exhaust pipe. I've had this truck less than a year and I know very little about Diesel engines. I at least need to get it running long enough to get home. The parking lot at work is really busy pretty much 24/7 and towing it out of there would get pretty dicey.
View 5 RepliesI have a 2000 F-250 Diesel that has started acting strangely. It starts and runs well, but every once in a while the peddle just stops working. Might be a second or so and then the RPM will go up. Or you may be running down the road and all of the sudden it just stops acting like it is getting enough fuel. Same thing it might last a second or so. Sometimes it might happen 4-5 times in a row over a few minutes and might not happen again for a day. Truck does not stall when this happens. It just does not go like it should.
View 1 RepliesI have the gas 5.4l in my 01 F250 Super Duty. I had to change out the leaking Heater hose before I could attack this other issue. The truck starts when it feels like it. I changed the fuel filter and it started fine. Then the next day it wouldn't. Later it would. However each time it does start it dies when throttled up. I am down to thinking it is the fuel pump. My question is, because changing the pump sucks about as bad as changing the heater hose. Can I install an inline fuel pump and deal with the sump pump in the tank later? Are there any Cons to doing this?
View 5 RepliesTruck was dead- 2001 F250 V10... Has a starter relay (solinoid) behind battery... put a new relay in there- no go- cleaner terminals... then I put key in start and shorted the 2 terminals in the relay and she cranked right up. That would mean the starter is still good correct?? something in the ignition system?
