I just picked up a 99 F150 for a song because it has an issue with the PATS system and the po doesn't have a clue on what to do with it. I bought a new ignition cylinder and Auto Enginuity to program the PATS. The problem I'm having is that I'm not getting anything from the OBD2 port and the #3 fuse is good. What else would cause the port not to have signal?
View 4 RepliesMy 03 5.4 the obd2 port isnt working i have tried 4 bluetooth adapters and a snap on scanner and nothing will connect to the ecm. im having problems and trying to read codes my check engine light isnt on but that don't mean anything. my truck is running really rich and blows a little bit black smoke when i rev it up after its been idling a few min and getting horrible gas mileage again. yesterday i went to start it and i had to crank on it 4 time before it finally started and then when i reved it up it almost died on the way back down but it caught itself. then today i go out and it starts right up and runs fine but its still running rich but i still cant get an obd2 adapter to connect to the ecm. I checked the fuse and its not blown my cigarette plug and the power port both work. i really dont know where to start in trying to figure out this problem. Right now iI don't really want to take it to a shop right now.
View 4 RepliesCigarette lighter works and shared fuse seems fine. OBD port even powers up my cheapo elm bluetooth reader. Unfortunately multiple different readers refuse to connect. I've tried disconnecting negative terminal for a half hour and trying again but no luck.

View 1 Repliescorrected vaccum leak. Still high idle and obd2 code 1506???
View 14 RepliesI've had a 0401 code on my truck for the last two years. I've replaced the EGR valve and the dpfe sensor a couple of times, with fomoco parts. Ive also cleaned out the egr tube that comes off the exhaust manifold. In this time I also discovered a couple of vacuum leaks and replaced those. I changed the pcv valve, tried running 93 octane gas, and had a mechanic friend run a special smoke through the vacuum lines to find more leaks. Also put a brand new gas cap. I have an obd computer and cleared the code repeatedly but the light always returns.

View 11 RepliesI was having intermittent fuel pressure problems. I replaced fuel pump and relay and was still having the problem. A figured out that wiggling the 20 amp fuse would cause the intermittent. Looking at the connections for the fuse, I can see one side was damaged. I figured I could pull the connector out from the back and fix the connector, but when I took the back off (see picture) I have a purple wire (labeled 1) going to one side of the fuse and a multi-connector (labeled 2) from one wire going to the other side. My luck, it's the multi-connector side that is damaged.
It Looks like the multi-connector goes to the Black and yellow wire. Instead of replacing the box, I figured I could just create an inline fuse for the fuel pump with the purple wire and splice it into the Black/yellow wire.
I can't see any problem with this, just looking for a second opinion. And I'm not sure how it would effect the relay. I can't find a fuse panel wiring diagram anywhere.
Looking for the wiring diagram with colors for which port should be what wire for the obd2 connector for my early 99 f-250. I actually think it is obd 1 on our trucks but you get the idea. My truck doesn't have power to the plug I guess. I have a guy plug in a scanner to take a look at everything but he said the plug wouldn't power up his scanner. Just trying to get this fixed. Another question, if I buy a AE does that require the truck to power up the software or does it get powered my the laptop?
View 11 RepliesI use to have the 95 f150 and 94 danger ranger. And I tried logging on after about a year and wouldn't let me so i started a new one, But im in a 98 f150 now with a 5.4 and 4x4. No i saw that there was a guy with the same problem as me but the thread went no where. So one night out of the blue my head lights or high beams will turn on. But everything else will. And all fuses are good and i look at the manual and there's no replays to mess with. Even though i already did. So what i had to do to get home was hot wire the passenger side bulb and i got power to both lights. So whats going on do u think it can be the switch ?. My power with started acting up a few days before this but I don't know if that has anything to do with the head lights.
View 13 RepliesThe power port in my dash went out. The diagram I got off the internet says fuse #39 or 41. Both are good. Where else should I look?
View 1 RepliesI have a 96 Ranger . Neither my cigarette lighter or the auxiliary right beneath it works. The fuse checks good at the panel and I also used one of the penlight 12 volt testers and it shows no voltage on the lighter housing. Could there be another fuse under the hood that shares that circuit or do I have an open somewhere and need to tear down the dashboard? I haven't been inside that dashboard since I replace my cluster and the lighter worked after doing so. But I wish to avoid going back in there.
View 3 RepliesI plugged in my basic OBDII scanner but I'm getting nothing back (the scanner works on my car so it's not the scanner). This is inline with the transmission shop where they said they couldn't connect either to my truck. But now the question is: now what? I don't think there is a fuse or such but how to troubleshoot the port.
Oh, and no, the CEL is not illuminated, just the ABS light remaining on from when my 4R100 was replaced a couple weeks ago. Can't connect to diagnose.
So I just bought a 2003 f250 v10 and I've plugged in my code reader and it couldn't get any info, so I took it to auto zone and they got an error code. I took a test lite to each little connection on the port with the ignition on and only got power to some of the metal connections on the port. So I'm wondering if all the little connections should have power? If so where should I start to look to find the problem?
View 5 RepliesI have a 03 F-250, 5,4L / AT trans, FX4 4X4 with power Windows/Locks/ Mirrors. I recently had a problem with my windows and radio wouldn't work. When I would start the truck the windows wouldn't move and the radio wouldn't work. (Noticed the clock wouldn't even light up indicating no power). I was reading on here about the battery saver relay could be the problem and found out it was, so that is fixed. However, before I found this website I went to hook up my truck to my code reader/ diagnostic computer and it gave me the error code of no power from the OBD-II port. I made sure everything was fine on the code readers side by using on a different vehicle. I recently installed a trailer brake controller but that uses a cable/plug under the center of the dash.

View 2 RepliesI went to open my trunk the other day by pressing the button on the trunk, and nothing, key in my pocket with a fresh battery (replaced in June). I then pulled out my key and pressed the trunk release on the fob and again nothing. I then went to the trunk release in the dash, and again nothing. I ended up pulling the key blade out and using that.... so inconvenient. ..
I did also check the fuse for the trunk release and it's still good...
So I was on my way to work on a semi-chilly morning here in Colorado. Every day as usual, a little upset in the morning, a little white smoke and after a good warm up i'm on my way. About 10 minutes up the road while accelerating on the freeway, I hit I guess the perfect RPM range (2000-2500) when all of a sudden my CEL came on. Right as the CEL showed up, the engine introduce to me a new skip and lost a bit of power. About 5 more minutes up the road, the CEL went off and the skip went away, unless in idle. I made it to work a few minutes later and the skip in idle was apparent for sure. I turned her off and just couldn't get her to turn back on. The injectors are just not firing, no smoke at all, they don't even sound like they're trying to fire almost like no signal to the whole engine.
I replaced the CPS, the IPR and unplugged the ICP to test if she'd go. I opened the fuel bowl and watched it fill up. I checked the HPOP level, it was almost full, maybe a quarter (between half) inch from the top. No codes.
She ran great until this, outside of needing glow plugs. When I was trying to get her started it was 60ish outside so I don't think glow plugs is the issue. It sounds like the Injectors are not firing at all, whatsoever.
I will note that I had a few fuses blow out of no where that I replaced, a trail light, OBD fuse and one other in the under-dash box. I had her dyno'd a few weeks back and the tech said she made great power but sounded like she had a little issue recovering from the high RPMs but I figured my injectors are tired.
I am having an issue with a fuse in the in cab fuse box, it just falls out. How to get the fuse box down from behind the dash ? If i could get it down I can repair the fuse holder, or something.
