Ford 6.0L Power Stroke Diesel :: Low FICM Voltage At Cold Start
So I am getting low FICM volts at cold start. The FICM will start at 46v and eventually drop below to 42v, but when I start to drive the truck the FICM volts go back up to 47.5, and my battery voltage goes back up to 13.8 to 14.1.
I am pretty sure my alternator is doing its job.
I left my truck sit for 2 or 3 weeks with out starting her or putting a battery tender on it, this was about two weeks ago. I have not had this problem before. Sounds to me like the batteries need a charge.
My batteries back up to full charge. I plan on letting the truck sit over night with a charger hooked to it.
Ford 6.0L Power Stroke Diesel :: Power Loss - Died - FICM?
So, I was on a road trip to Arkansa from Missouri when my truck started loosing power and eventually just died. After I tore through some stuff, I realized the ficm was just floating around off the brackets and even better yet, missing the top cap where you voltage test. And to my great luck, there was a small coolant leak that dripped it's way right into it.. So now I'm looking at replacements and it looks like I'm going to go with the Bulletproof Diesel ficm. But my question is, can I just swap them out and go.? My truck is tuned with an SCT tuner and was tuned up when it died. Should I tune it back to stock before I put a new one in or put the new one in and then put it stock and retune it after that.? Or is it more complicated than that and I should just let my mechanic deal with it.?

Well, coming home from work Friday and my truck turned on the check engine light. I did not notice any loss of power or other driveability issues. When I got home I pulled the DTC's. I got P0264, P0273, P0276, P0279, P0611, and U0306. The first four being low voltages. The Second FICM. And the last cylinder 6 misfire.
I sent a message to Ed at FICM Repair asking if there was anything to check before I pulled the beast. He said no it needed service no matter what at this point. BUT, I needed to test batteries and alternator. So I spent some time today pulling off my FICM.
I went ahead and pulled the EBP sensor and tube off from the exhaust manifold. The manifold end was very clean. BUT, the sensor end had a noticeable restriction. I would guess a 40% restriction. I cleaned the tube and the sensor and put it back on.
Next I moved to the EGR. I pulled it off and it was dirty but not what I would call restricted. The valve moved freely. I cleaned it anyway and blew out the manifold before I reinstalled it.
I have the batteries on a charger right now. Once they each charge for 12 hours each I will let them sit a day or two before I load test them. They are about four years old, AC Delco 60 month 875CCA batteries. I have had problems the last 6-8 months with staring the truck. If she sits for more than 3-4 weeks without being run she turns over slow and won't start. So I have had to jump start her a few times. And before you ask I have done a parasitic check and only have .05amp draw. So maybe the alternator is getting weak.
On that note I pulled the alternator and will get it bench tested this week. While I was there I noticed the top grooved and smooth idler pullies were a little "wobbly" so I yanked them too and will replace. Might as well do the belt while I'm at it. Boy this is going to get expensive real fast.
So, I decided to go ahead and replace the bottom coolant recovery hose and the long hose/pipe heater hose too. Boy it never ends. Oh well. I would rather do it now while I have stuff pulled off and it is easier to get to. Ordered those parts from RockAuto to the tune of 219 dollars. OUCH!!!
I accidentally broke my new engine oil dipstick while I was trying to get to the FICM!!!! CRAP!!!! More money. So......... Is there anything else I might want to look at while I am there?
The truck is 2006 F250 6.0 PSD CC SB 4x4 mid optioned XLT with 108,000+ miles. I have a 4" turbo back exhaust, AFE Cold Air Intake, Blue Spring, Hypertec Power Program 3 on the lowest setting, and an after market intake elbow at the intake manifold and an engine oil bypass filter. Turbo was pulled and de-coked about 18,000 miles back. Otherwise no issues. The 90,000 mile service was done about 10,000 miles ago. She gets regular services.
How about methanol injection? Will that keep the intake clean from the EGR sludge? I'm not thinking about added power, just keeping things cleaner? I plan to do the Atlas 40 when the FICM gets repaired.
Ford 6.0L Power Stroke Diesel :: FICM Voltage Drops To 40 On Cold Mornings
I've noticed on mornings when it's around freezing or colder my FICM voltage drops down to around 40. after about a minute it creeps up until it's in normal range, about 48 volts or better. This only seems to last about a minute before it's in normal range. No check engine lights though.
View 14 RepliesFord 6.0L Power Stroke Diesel :: Crank / No Start - Bad FICM
2003 6.0, all stock. Crank, no start with an occasional sputter when it actually shows FICM SYNC = YES.
It had the following relevant DTCs when I scanned it:
P0261, P0270, P0276 and P0279 - Cylinders 1, 4, 6 and 7 - Injector circuit low
P132B - Turbocharger/Supercharger boost control A performance
P2614 - CMP Open circuit
P2617 - CKP Open circuit
CMP/CKP SYNC transitions to and maintains YES while cranking, however FICM SYNC transitions back and forth between YES and NO while cranking. When it transitions to YES, a cylinder or two will fire when FIPW comes up, but FICM SYNC almost immediately transitions back to NO.
Based solely on the scan tool results, Cranking shows IPR DC at about 50%, ICP PSI ~1500, ICP V ~2.0. These are stable and steady. FICM main power is at 49.5v and drops to 49.0 when it fires the occasional injector while cranking. RPM reads above 150 while cranking.
I'm thinking that since CMP/CKP SYNC stays YES and is stable and RPM reading is consistent, the CMP & CKP sensors and circuits are most likely good. I'm thinking with the codes for injectors 1, 4, 6 and 7 it probably points more toward a FICM issue.
Another thing that may or may not be relevant is the pre-cycle clatter sounds off to me. With an ambient temp of about 70F, the pre-cycle seems to repeat 3 times. The second and third cycles sound worse than the first. This is in the video below.
I work on far more 7.3s than I do 6.0s, so I'm looking for anything I may have overlooked, a second/third/fourth opinion, or if there's a flaw in my logic for someone to point it out.

Ford 6.0L Power Stroke Diesel :: Rough Idle - FICM Is At The Start Of Going Out?
So after replacing all injectors, I was getting a rough idle and drive. Got an imbalance on 5 & 4. Cleared out codes and 5 still showed. The guy doing my work and I couldn't trace it to anything so we thought well maybe we got a bad one. Did fail the buzz test. So got a warranty one and put in. Wouldn't you know it's still not running quite right. Only thing we can think of is maybe the ficm is at the start of going out. Voltage reads good still though. Staying constant at 47/48. Is more noticeable to run rough when starting from cold then smooths out but you can still make out/feel an injector going in and out.

My f250 was parked this winter to get work done. I had put a new exhaust on and while crawling on the engine bay it had kicked the fuel reset by the passengers kick panel. After pressing that button the truck would not start and threw FICM codes. (Power low to FICM) and my Scanguageii had said that power was very low (27 volts) during cranking. I sent the FICM to FICMrepair.com. Today I had put the FICM back into the truck and went to start it. I cycled the plugs 3 times and started on the 4th. The truck did not start after this and had thrown more ficm codes. What it could be?
View 12 RepliesFord 6.0L Power Stroke Diesel :: 2004 - Crank But Would Not Start - No FICM Sync
2004 6.0 Truck has been slow to start and sometimes took a few tries to get it to fire up. On monday the Truck would not start. The FICM was not getting sync. I figured it could be a bad connection to the FICM. I pulled the FICM, cleaned the contacts and reconnected it. The truck fired up. It ran all day Tuesday without incident but wednesday morning it would again not start. Again what was missing was FICM sync. This time disconnecting and plugging back in the FICM did not fix the problem. I have spent the last two days troubleshooting and am out of things to try.
The problem as it stands right now
The truck will crank but not start. Scanner says it has oil pressure, a steady 48v (FICM has new power supply). The IPR sits around 50% when cranking at 1200psi. However, the FICM will not get sync. I have worked my way down and tested both the Cam and Crank sensors from the PCM. The Crank sensor has a resistance of 360 ohms and produces a AC voltage of 500mV when cranking. The camshaft sensor produces 100mV AC when cranking (camshaft sensor was replaced as the original produced AC voltage seemed low 20mV, new sensor produces 100mV). I have tested the camshaft sensor at the sensor and at the PCM connector. This has lead me to believe both the cam and crank sensors are ok and their signals are being probably transmitted to the PCM.
I have tried to check the inputs to the FICM to confirm the signals are getting there. I was unable to find a good pin out diagram for the 2004 FICM but what I found told me the crankshaft was pin 5 and the camshaft was pin 10. When cranking, pin 5 (crankshaft) did not produce a signal and pin 10 (camshaft) had a 200mV DC signal. Despite searching I have been unable to find what the input signals to the FICM should be.
Right now I suspect bad wiring between the PCM and the FICM, or a bad PCM. This is based on having good signals to the PCM, but (what I think may be) a lack of crankshaft pos. sensor signal to the FICM. I am specifically looking for what the crank/camshaft pos. sensor signal at the FICM should be, as well as confirmation/disconfirmation on the diagnosis of bad PCM or PCM-to-FICM wiring

Ford 6.0L Power Stroke Diesel :: FICM Will Usually Start In Low 30s And Gradually Work Up To Upper 40s
So, I've been having cold start issues for a couple of years now especially when temps get below 25 or so. It started with virtually no issues until temps got into the 20's but got to the point this year where it run a little rough at startup even in the summer. Once ECT gets up around 140* it runs pretty good.
I took it to a diesel shop last year and was told I had 1 bad injector and a bad glow plug. I couldn't afford to do the work, so I waited.
Now after researching this site, I'm more inclined to think it may just be the FICM. I've seen scangauge numbers in the low 20's up to 48.5. On cold morning FCM will usually start in the low 30's and gradually work up to upper 40's. The batteries were both replaced 2 years ago, but I probably should give them a load test. The alternator voltages vary from 11.0 to 12.5 when cold and 12.5 to 14 once warmed up. I have noticed that the AC blower will slow down a little when I sit at a red light, and then pick up again when taking off. I don't notice it with headlights or anything else.
According to Bismarc's spreadsheet, alternator numbers seem to be in the acceptable range, but I don't want to get a new FICM and fry it with a bad alternator. I can get the alternator or the FICM now, but if I need to do both at once I'll need to wait a bit longer.
Ford 6.0L Power Stroke Diesel :: 2003 F250 Won't Start After Replaced All 3 FICM Connectors
I have an early 03 F250 6.0 that won't start after I replaced all 3 FICM connectors, also # 8 injector pin and connector. It has been almost impossible to start before the repair.
I checked the grounds on
Pins #1 2 3 22 they were all .5 ohms
Pin #32 was 1.0 ohms.
Pins #7 27 were 12.7v ( battery voltage)
I have double checked all pin connections and wire colors, they are in the right holes, I haven't done any cranking voltage tests, as I am alone. The FICM has 48.2 v.
Ford 6.0L Power Stroke Diesel :: 2007 - Cranks But No Start - FICM / Cam / Crank Sensor No Sync
2007 6.0l cranks but no start. Read all the forums and I think I performed all the checks. Getting a ficm/ cam sensor/crank sensor no sync. I'm also getting 84.70% at the ipr while cranking. Do I have multiple problems? Watched videos on either the ficm or ipr percentage but not one that had both problems. Getting injector clatter and fuel pump runs. Didn't see anything obvious with the harness.

I just bought a 2004 F350 6.0 cclb 6 speed with 260k on it. The previous owner seemed to have taken good care of the truck. It is basically stock with the exception of the blue spring mod, and a sinister diesel coolant filter. Anyways, I brought the truck home and it ran great. Now I have an issue that needs to be addressed.
The issue: I am experiencing a intermittent loss of power, stall, or stumble when engine is cold. After sitting all night the truck will start fine and idle fine. But when I try to accelerate and bring engine RPM up the engine will stumble and lose all throttle response, when this happens the WTS and WIF light flash. Sometimes it just stumbles, sometimes the truck will actually die and then restart. The issue seems to go away after the engine has reached operating temp.
I did some research on the issue and it seems there is actually a TSB out from ford for this issue. It explains that some 2003-2004 6.0's might have wiring harness chaffing issues. This is what the issue I am having seems like to me (shorting harness). I looked up codes on the truck and there is an active code (#8 glow plug circuit fault). I did a short visual inspection of harness and didn't see anything out of the ordinary. But i wonder if it would be worth changing both sides of the glow plug harness?
Ford 6.0L Power Stroke Diesel :: Power Loss On Takeoff And Then Stopped Now No Start Just Turns Over
So loss power on take off and then stopped at store quick shut it down. Came out of store ten minutes later no start just turns over and over. I replaced IPR last year the one on passenger side near frame if that's correct and perhaps this is the ICP near back of engine?

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 replaced injector couple weeks ago. I hooked up to livelink thru sct because it was throwing a low voltage for ficm code. It is staying at 48 volts tho. I don't see any voltage from my glow plug relay, and I have a low voltage for my egr valve. Is it just bad luck that everything broke at once or is there a fuse or a connector that I forgot to plug in.

View 3 RepliesFord 6.0L Power Stroke Diesel :: FICM Has Been Dropping To 44v Occasionally
My ficm has been dropping to 44v occasionally so I have ordered a 270a alternator from Ed at ficm repair along with the complete battery cable kit. I also took ends advice and bought two new odyssey 65 series batteries. I went with bpd 6phase ficm though because I like the idea of the extra phases to share the load and back up the 4 primaries. I am also doing the blue spring upgrade while under the hood as well.
So my question is this.... My truck is bone stock no mod 53k mi. The bpd ficm can be set to 48,53 or 58 v. I do not see the need to do 58v but have seen a lot of guys doing the 53v option. What is the advantage of 53v? I know if you run 220 thru a 120v light bulb it will burn bright as hell for a little bit till it blows, is this the case with running a higher voltage ficm? Will it eventually wipe out injectors? Or even the ficm processor board? Should I just stay at 48v setting?
Ford 6.0L Power Stroke Diesel :: Won't Restart FICM Drops To 0?
This is the second time this has happened to me . Truck runs fine shut it off go to re start and it's a no start. I can watch the ficm volts drop to 0 from 48.5. Then it's 0 until it decides it gets power again?
