Ford 7.3L Power Stroke (1999-2003) :: Possible To Add More Circuit To Fuse Box?
Aug 11, 2017
OK I'm putting a plow on my truck. I am wondering if it's possible to add more circuits to the fuse box in some of those unused slots?

Ford 7.3L Power Stroke (1999-2003) :: Codes For Exhaust Pressure Circuit Valve / Intake Air Heater Control Circuit
I have an emissions test coming up. I have 3 P codes that I'd like to eliminate before then. I don't want to "fix" the issues they are telling me about. Just make the codes go away. I know why they're there I just need to get rid of them.
What I have coming up is:
P0475 Exhaust Pressure Circuit Valve (result of EBPV delete)
P0541 Intake air heater A circuit low (result of aih delete)
P0640 Intake air heater control circuit (also result of aih delete)
What resistors I'll need and where to put them in?
Ford 7.3L Power Stroke (1999-2003) :: 2002 F250 - No Power To PCM Fuse
I just finished a cab swap and I'm having a little trouble. Here's a link to what I've done : [URL] ....
KOEO the WTS light, battery light, SES light all stay on and no power to fuel pump. No communication with PCM (using AE). All fuses are good, but no power to PCM fuse (#22). When I apply 12v to #22, the truck will start and idle - but poorly because I still don't think fuel pump comes on. The idiot lights all stay the same.
I did get to pull codes while it was running and got stuff like IAT circuit high (its not plugged in), fuel pump relay short to batttery, and a few other short to battery things (park assist stuff IIRC). I thought that might have something to do with the redneck idea to boost the fuse with an external power source?
Just thinking while typing, I don't have 3rd brake light hooked up yet (just thought of that, I'll hook it up first) and bed/bumper are not installed, so no tail lights or park assist stuff is hooked up. I'm also not using overhead computer, so it's not plugged in.
My next step is to go back through all of the connectors and make sure something isn't 1/2 way plugged in or possibly plugged into the wrong place(s).
Looking thru the wiring diagrams is not a strong subject for me, but I was trying to figure out how power gets to the fuse and how PCM relay works (does it complete circuit to ground to energize the coil?).
Ford 7.3L Power Stroke (1999-2003) :: No Power To Fuel Pump / Fuse 30?
I have a 2003 F250 and dont have power at fuel pump, or fuse #30. I put power directly to fuel pump and it worked and truck fired right up.

View 1 RepliesFord 7.3L Power Stroke (1999-2003) :: Fuse To The Starter Keeps Blowing
I had a problem with this issue a few months ago, was 45 minutes away from home, blew the fuse to the starter. Switched another one in, blew it too. Had it towed to a shop, they did some diagnostics, felt like it was a short in the starter, replaced it and all has been well (as far as that particular issue) until this morning. Got in it, turned the key it cranked for less than a second and stopped. I pull the fuse, sure enough, blown. Swap it with another, it blows.
I know I have a bare wire in the column, the OD light wire is chaffed, I fixed it before but it must be worn again because I can get it to light up depending on positioning of the shifter lever and as I recall, every time the fuse blows the steering wheel is cranked to the left.
Ford 7.3L Power Stroke (1999-2003) :: F350 Lost Power - Fuse Panel Under Steering Wheel Shorting Out
So I have a 1999.5 F350 diesel and the fuse panel under the steering wheel is acting up. I was driving my truck home the other night and I lost power and my truck shut off. I have had a problem in the past with the #30- 30 amp fuse ( controls the PCM and glow plugs from my understanding) that is under the steering wheel, I replaced the fuse and everything started working normally again. Until the other night when my truck shut off, so I replaced the fuse the truck drove again for 20 feet died again, I was able to hold the #30 fuse and allow my truck to start up again but would eventually killed the PCM and shut off again and would not start up due to what I believe the fuse location shorting it out and killing the power to the PCM preventing me from starting it up again.
I had my truck towed home and charged the battery and it started up fine the next morning. If I push on the #30 fuse my truck the shorts out and kills the power, I do not know if this is normal? The fuse is sitting loose in the fuse holder is there anyway making it fit tighter to prevent it from being so loose? I have read every other post online about the problems and tried everything they have recommended but still can not figure out what was wrong with my truck. I disconnected the fuel filter heater, and also the wastegate solenoid to see if that would prevent the truck from shorting out if I pushed the fuse it did not work.
What the problem could be causing the #30 - 30 amp fuse to be shorting out preventing everything from working? Or how to test the fuse panel and all the relays?
Ford 7.3L Power Stroke (1999-2003) :: Fuel Pump Fuse Blown
So the other day my 20amp maxi fuse for my fuel pump decided to blow, put a new one in & everything has been going good since. Is it just a fluke or is this an indication my pump is going out? I inspected wires off the pump & connections for corrosion & that's good, fuel filter is also new about 2 months ago & I always run #1 diesel with a little additive in the winter.
View 1 RepliesFord 7.3L Power Stroke (1999-2003) :: Buzzing Noise From Fuse Box Area
My friend and I were working on my truck and he was testing my AIH relay, as he was testing it the fuel pump was clicking on and off a few times over about 10 minutes. He explained that the current must be back feeding through the system and activating the pump. After testing the relay he determined that it non-functional / broken.
When we went to start it there was a strange buzzing from the fuse box area. After testing all of the fuses and then his code scanner not being able to connect to the truck we can only figure that the PCM is done.
The truck will turn over but not start. Any time the key is in the run position the buzzing noise is there unless you pull the PCM relay or the IDM relay. He says (I know very little about this stuff) that the IDM relay is trying to close but because the PCM is fried the IDM is not getting the signal to do so....?
So what now? Do I need a new PCM? He said something about it need to be reflashed to match the old one, is that right? Are all PCMs equal? What else should I know?
Ford 7.3L Power Stroke (1999-2003) :: Fuse Keeps Blowing Out - No Parking Lights?
i have a 99 f350 psd, my problem is i don't have normal; FONT-SIZE: 100%; COLOR: dark green; FONT-FAMILY: inherit">parking</NOBR> and instrument lights, it blows fuse number 8 as soon as i turn the switch on. i checked all the wiring on my tail lights and the trailer hookups. i even disconnected the wiring harness going my tail lights and trailer hookups and it still blows the switch. #8 fuse is trailer tow electronic brake, illumination, park lamps, trailer tow park lamp relay coil. it also blows #4 fuse which is trailer tow backup lamps, trailer tow park lamps.

Upon trying to start my 2003 f250, it keeps blowing the 15A "Transmission Range Sensor then to Starter Relay Coil" fuse. Initially the truck would still start if i did not use the aftermarket Viper keyless start. however, now it doesn't start at all and keeps blowing fuses. I contacted the guy that installed the alarm thinking it might be something on his end. He walked me through reconnecting the factory starter wires which would isolate the issue if it was something on his end. it's still blowing fuses. battery terminals are good and clean.

Batteries charged, connection & cables checked. After turning ignition switch, gauges on dash jump around & starts clicking in fuse panel. Top left relay then clicking sound from beside steering column on right side next to trailer brake box. Been having electrical issues & something draining batteries...had absolutely no cold start this winter. No decent mechanics here other than to be ripped a new one @ local dealership.

Need to diagnose this before I start ripping wires:
Truck started blowing the # 8 fuse under the hood tonight (15 amp #8 - trailer tow electronic brake illumination, park lamps, trailer tow park lamp relay coil fuse) which also controls the dash board lights (can't see gauges at night) and the tail light lights (brakes lights work) are out too. Figure I have a short somewhere.

View 1 RepliesFord 7.3L Power Stroke (1999-2003) :: F250 - Dome Light On And Off - Noise Under Dash Fuse Panel?
I was to leave tomorrow for a trip with three horses. Last night when I parked my truck the dome light went on and off and there was a noise (like a relay opening and closing?) coming from the area. (I have been having issues with the turn signal getting "tired". At times they would only come on solid then other times try would quit after sitting at a long light.)
Checked my manual for fuses to this issue and I removed the fuse in the spot indicated for the "dome and courtesy lights", number 14. Actually I had removed spot number 15 (5amp). This ended the noise. Drove the truck after and all seemed in order, cruise control, turn signals, interior lights! This was the incorrect fuse according to the book! This event occurred with the ignition in the OFF position. Not wanting to start my trip before I get this in order.
Ford 7.3L Power Stroke (1999-2003) :: 1995 F250 - Factory Remote Keyless Entry Blowing Fuse
I have a 95 f-250 psd with factory remote keyless entry. about 3 weeks ago i had a fuse blow that powers the keyless entry module, speed control, and a number of other systems.
If I replaced the fuse it blew right away so i got my wiring diagrams out and started unplugging parts of the circuit and my last attempt was to unplug the keyless entry module. presto no blown fuse so i got a module from a junk yard fixed the problem and now it has happened again. same exact thing. unhook the module and no blown fuse. i took the first module apart and saw no burned parts and no visible damage but here i am blowing fuses with no door locks, dome light and a few other things.
The fuse that blows is fuse 8. I am a mechanic and have full access to anything I need. I have another module under warantee but I want to be sure that its not something other than the module causing problems.
Ford 6.0L Power Stroke Diesel :: 2003 - Crank No Start - Code P2285 ICP Low Circuit
So yet another crank no start. Truck is an 03 55k miles The guy I bought the truck off of told me the turbo had been reconditioned about 1000 miles ago. Drove the truck another 1000 miles or so and now having issues. I went to start truck up and noticed it took awhile longer than normal to start up and when it did finally kick over, truck and no power at all. Would idle a bit rough sounded like no turbo spool at all when given throttle. Shut the truck off right and hooked up scangauge to it went to start it and nothing.
Did throw p2285 code ICP low circuit
Values read on scangauge are as follows:
FICM Main Power 48.0V
FICM Logic Power 10-8V
FICM sync is good
ICP Pressure 1540psi on crank
IPR duty cycle 14.8% Key on engine off/48.8% while cranking
At a bit of a loss as to where to look next, would really like to troubleshoot down to the right fix instead of just throwing parts at it. Have read after sitting the turbos tend to stick and need cleaned or replaced. After being cleaned only a few thousand miles could it be stuck again? Seems like I have spark, fuel, oil just acts like its not getting any air.
Ford 6.0L Power Stroke Diesel :: 2003 F250 - Truck Started Blowing Fuse 45
I have an 03 6.0 F250. My truck started blowing fuse #45 and it would kill my gauges (fuel, oil, mph, rpm, temp, trans temp, and odometer) and I was just replacing the fuse and putting off the repair.
However, the most recent time my gauges blew, the fuse did not, and I put in a 20 amp fuse, in hopes that it would not blow so quickly, bad idea. So naturally, I ordered a new shift lever, in hopes that it would fix the gauges and I wouldn't have to deal with it anymore, but I think it was too late and something else needs to be replaced. What I could possibly have blown by having a larger fuse in there?

Last November I forgot to plug my truck in and it got down to 0, my girlfriend tried unsuccessfully to jump start it. When I got home I jumped it and got it running. I took it down to a heated shop to troubleshoot the glow plug circuit. I discovered it was not getting 12v to the glow plug relay. Also I started it and tried to back it up in the shop, when put in reverse it killed the engine, not lugged it down it was like you shut the switch off.
Also I discovered if you turn the lights on it kills the engine immediately. It will not crank with the lights on either. So far I have replaced the computer,ignition switch,batteries, and cam positioning sensor. Now comes the weird part!! I decided to get it running and pull the bulbs out of the back up lights I pulled the drivers bulb first then the passengers side bulb. When I pulled the passengers side bulb it killed the engine.
It is not my daily driver so it still sits in my shop. I have a hunch it's a ground issue but I've checked and cleaned up all the grounds I can find and it still has the problem.
