Ford 6.0L Power Stroke Diesel :: 2003 F350 - Relay Noise Under Dash
I have a 03 6L Ford F350 and for the most part trouble free. Any way lately I have been getting a clicking noise that sounds like a relay clicking under my dash when my truck is running even when its just idling...
I don't always get it but it has become more common that last few weeks. So I stuck my head under the dash and it sounds like it coming from that little black box's that is attached at the base of the gas pedal ? Could be coming from fuse box cause that what i was going to go after but doesn't sound like it, SO what is the little back box for on base of gas pedal?
Ford 7.3L Power Stroke (1999-2003) :: Starter Relay On Fender - Wiring Diagram
Any pic or wiring diagram of the starter relay that is mounted to the fender. I'm trying to start the truck finally but it's just cranking and I think I might have mixed up the wiring. Is there supposed to be a constant hot at the glow plug relay when the ignition is off?

I was going to order a ECT gauge and was wondering where to mount the sensor. I have already used the port under the T-stat for the coolant filter. The gauge sensor is a 1/8 NPT. Would the block drains be a good location, or is there another location that will work.
I know the coolant filter housing has a port, but I would prefer the sensor be on the motor.
Ford 6.0L Power Stroke Diesel :: 2003 F350 - No Power On Cold Start
I recently bought an 03 F350. I've noticed on cold starts that it has no power. After about 5 minutes it runs very well. I have not noticed any misfires or smoke and there are no codes thrown. Based on what I have read here, I assumed it was a FICM issue. I just got done testing it and it was at a solid 48v with 1 dip to 46 on engine crank. I'm baffled at this point. The truck literally has no other issues except low power for the first 5 minutes.

I noticed the aftermarket controller in my 03 F350 is not working. I am wondering where the fuse(s) might be located. Under the hood? Are they fuses or relays?
View 2 RepliesFord 6.0L Power Stroke Diesel :: 2003 F350 Will Not Start
I have a early build 2003 f350 6.0. It will not start. Readings are good. ficm 48 to 48.5, synced, icp volts .30, icp climbs above 1200 psi, bat 13 to 13.5, ipr 14.8 to 40, fuel pressure 82 psi during crank..... will not start. Last week tore it down and replaced the tube of the hpop, found a leak in map hose and cleaned the turbo (vanes, ring). Ran ok for a week... shut it off and my sons baseball practice and will not start.... towed it back 2 days ago and nothing..... just cranks... I am at a loss. Another question would be where do i air test the hpo system on this truck.... ICP and IPR are in the back of the motor and hard to get to. I have read there is a way to do it under the valve covers.... not sure.

I have a 2003 Ford F-350 super duty 6.0. A few weeks ago it starting loosing power, it wouldn't even go up to 15 mph. It now won't even move. There is 0 power. When I press the gas the motor bogs down to a very low idle and wants to die. I also had recent trouble with it starting. It would wind up to a very very low idle and about a minute later it would crank up to full idle. I changed the fuel filters (on top of the engine and under the cab) and also changed the fuel pump under the cab. After that I still have no power when pressing the gas it will still act like it wants to die.

03' F350 Crew Cab DRW FX4 Lariat 6.0
180k miles
Has EGR Delete
Blue Spring Kit and recent Fuel Filter Kit
Last Friday I got the truck back from a local mechanic that had replaced the water pump. Took it out to put fuel in it last night. About a mile from the house it felt like it bucked then died. While still rolling I stuck it in Neutral and started it back up. Got fuel and back home, no problem. Total trip around 4 miles.
This morning I get about a mile from home (other direction) and it does the same, engine quits and it rolls to a stop. Except now it won't crank. Has electric power, just won't turn over. Both batteries are pretty new Napa big CCA ( I believe 800 ).
I walk back home and get my '04 F250 6.0 (180k also) and drive back to the stricken 350. Thinking a battery may have crashed a cell I remove the ground from one battery and jump it off with the 250. No difference. Reconnected battery #1 and Disconnected battery #2 ... Same thing, no crank.
I didn't really think it was a battery issue since it started fine, but if one of them had crashed a cell it could have shorted. No dice.
Now I'm thinking it may be the fuel pump. Would not having line pressure keep it from at least cranking? IE like a safety feature so the injectors don't try and run dry?
Ford 6.0L Power Stroke Diesel :: 2003 F350 DRW Won't Start - Not Getting Enough Fuel?
ICP and IRP changed both fuel filtrs and Blue spring put in. HPOP Pressure is over 1600PSI when cranking with 2.5 to 4 volts.
Will try to run but acts like not getting enough fuel. If I loosen the lines off the upper filter housing lots of fuel runs out. Lots of smoke when cranking also.
FICM volts are 48.5.
Reading with Scan Gauge 2.
The truck is a 2003 F350 DRW Stock 6.0 with 433000 on the odometer.
Ford 6.0L Power Stroke Diesel :: 2003 F350 Won't Start When Warm
I have a 03 350 with a 6.0 . The truck starts fine in the morning and runs great all day as long as you don't shut it off. It's not going to start until the morning. It will crank over fine, the fuel pump seems to be working, its like there is no power to the injectors. I don't have a wiring diagram so not sure which relays are for injectors. Could the ficm be causing it? Is there a site where I can download a fuel sys schematic ?
View 4 RepliesFord 6.0L Power Stroke Diesel :: 2003 F350 Truck Revving Up Out Of No Where
So I'm having a problem with my truck revving up out of no where. Happens more when I'm driving. It only shoots up a little bit but sometimes goes up 1000 more rmps. Happens for a quick second then stops and does it again. I've had the ckp replaced and it has an egr delete. Other than that it's stock. I got home and let it idle for a minute. The rpms fluttered up and down in small increments and almost stalled out. What is causing this?
View 4 RepliesFord 6.0L Power Stroke Diesel :: 2003 F350 - No Start Below 55 Degrees?
Just purchased a 2003 F-350 Super Duty Lariat Crew Cab w/ 6.0L Powerstroke Diesel w/ 192,000 miles. This truck will be used exclusively for pulling my 36', 8,000lbs travel trailer. I have a 2011 F-150 Ecoboost as my daily driver. The 2003 was purchased from a used dealer in Texas and is in immaculate condition and was definitely not a work truck. It was a 55 degree day and the truck was inside their building when I picked it up. No starting issues then and drove it the 3 hour 70-75mph trip home, with 2 stops on the way (wife was along) with no issues. Started quick and ran like a champ. The next morning it was 32 degrees outside and it would not start. I cycled the key on & off several times prior to starting and still no start. Plugged the heater in and 1 hour later it fired up. I have noticed since that if the outdoor temperature is below 55 degrees, it will not start without being plugged in. When plugged in, it starts easy, no smoke, purrs like a tiger at idle and runs great. I Have started on a mental list of things to check.....here goes:
1. The dealer stated he just changed the oil & filter. Can't rely on this 100 percent so I plan to put new 15W40 oil and filter in. Oklahoma summers are pretty warm.
2. Check the FICM for 48 voltage output.
3. The glow plug indicator on the dash is working. The colder it is outside, the longer it stays on. If the indicator is working, is this an indicator that the glow plug relay is working? Anyway....plan to check this relay.
4. Pull one or two glow plugs, ones easy to get to, to verify their function.
5. Check both batteries....I assume they will have to be disconnected from one another before doing this.
I have been working on gasoline engines for 40 years and no stranger to busted knuckles & dirty fingernails.....just new to diesel engines. I am impressed however with their construction and method of operating.

View 3 RepliesFord 6.0L Power Stroke Diesel :: 2003 F350 - Intermittent Long Crank When Hot
2003 6.0 will fire within 2 seconds when cold, literally a "bump the key" and she fires up scenario. Recently and only when the engine is hot I'm getting extended crank times and sometimes it takes several attempts for the truck to start. I replaced the HPOP with an upgraded pump after the factory HPOP went out at 311,000 miles. I know this sounds like a standpipe leak scenario but it doesn't act up all the time, sometimes it fires right up even when its hot. my thinking is a leak is a leak and only gets worse.
My IPR is reading in the 26% range, FICM is steady in the 47.5 to 48 volt range and at idle 585 to 600 psi on the ICP with a good FICM sync. I'm going to to use my scan gauge and see if I can catch an extended crank scenario to see if the ICP is reaching 500 psi but is there somewhere else I should be looking? FICM relays possibly? I've noticed when i turn the key on I'll hear the fuel pump,vacuum pump but the clicking sound is very brief or nonexistent (not sure what the clicking noise is from I assumed glow plugs but its absence is noticed)...
Ford 6.0L Power Stroke Diesel :: 2003 F350 - Intermittent Battery Light On / Off
I have a 2003 F 350 Crewcab 6.0 liter SD. I was preparing my truck for the first haul of the Summer. I noticed that my batteries were on their way out after 2 years old. I replaced them and noticed I had an intermittent battery light coming on/off on/off. It seemed like only at lower RPMs. So the day of my trip, I ended up changing out the alternator.
The trip went fine, however, I noticed that pesky battery light came on and then off a few times. I also got a hot plastic type smell from the front of my truck.....you know that hot plastic smell Anyway, I got home just fine. Via Torque Pro, my battery volts were reading 12.2ish when my battery light came on, but then would quickly return to 13.9.
Since I"ve been home, I have read about fixing the grounding points for our trucks and also adding a second ground wire and a second hot wire from battery to battery. I can not find exactly where the ground's lead to. I still have that fricking battery light coming on .....more often that not. How to chase this problem.
First I need to find out where the ground wires go to. My volts of recent have been reading 11.5-12ish when the truck is running and the friggin battery light is on. I did search and found a few links to this problem, but where to find the grounding points.
