Ford 6.0L Power Stroke Diesel :: Crank But No Start / Fluctuating RPM / No Sync
Jul 9, 2016
Truck Details:
2004 6.0 F250 extended cab.
Mileage: 1,162,000 Kilometres (the dash stopped at 999,999)
Egr is deleted.
Motor has approximately 120,000 miles on it.
The previous owner delivered campers with it. He said that almost everything in had been replaced except the transmission.
I've had an intermittent crank, no start since I've owned the truck. (2.5 years) It's only happened maybe 5 times and the second attempt was always successful....until yesterday morning.
It threw a few codes but none I believe related to the no-start. One code for a transfer case issue, one for a turbo under-boost, one for the ac clutch not communicating, one for the exhaust pressure sensor not communicating. I would list the actual code #'s but after the first scan I reset them due to my ignorance.
While cranking I get the following numbers:
FICM LPWR- 11 to 12.5 volts
FICM MPWR- 47.5 to 48.5 volts
ICP v- up to 1.8 volts
ICP pressure- up to 1493 psi
IPR %- 15 to 55%
No FICM sync
No ckp/cmp sync
RPM- 0 to 60 and fluctuating
FUELPW- 0.00 ms
I've checked hertz across the red and orange wire at the centre plug of the pcm while cranking and i believe it tested good at 1.4 hertz. The batteries are both getting old and I plan on replacing them but the voltage seems adequate.
The following Forscan tests all checked out good.
PCM KOEO
PCM KOEO injector electrical
TCM KOEO
There were a few others but I think they're irrelevant and they checked out good anyway. I've visually inspected for chaffing but I need to look harder still. There were definitely no codes regarding the cpm, ckp or ficm. Based on what I've read, the fluctuating rpm reading should point to something I'm not aware of.

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

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.

What could be causing my turbo to be fluctuating while accelerating? I can definitely hear the difference in the sound of the air and today while towing my camper I could even see the dash gauge bouncing around some.

The truck was running fine then I shut it off one day and it wouldn't start back up long powerful cranks but wouldn't start pulled the valve covers checked branch tubes and dummy plugs all looked good (not for sure though) replaced the icp and even tried unplugging it after the hot crank no start to see if that worked because that was the only a code I threw but alas it did not work.
I did a air test and closed the IPR valve via fancy tool and was getting some minor gurgling out of the oil filter resivuar and was guided to change the hpop being that was the beloved issue I couldn't get the j-tube out to inspect but everything else was clean as a whistle ... I was getting some air flow threw the oil filler cap and the air intake box on the driver's side valve cover but was told that is normal but not sure how normal when I replaced hpop it appears it stopped gurgling as much.
When I did the following air test but it started when cold but then it struggled but it did start then my batteries died out turns out I do have a bad negative connection I getting the batteries re charged gonna pick them up today and tighten that connection along with a new air filter via reading in the hanes manual that can sometimes cause a hot crank no start .

I have a 2004 6liter. I parked one day two weeks ago and a went out last week to move it and I will only crank over. No fire No start!!!! Have new batteries. New fuel filter and have fuel coming in to the fuel bowl. I have gone over the harness, checked my fuses. I do not have a reader or scanner. Any recommendations. I want more than just a code scanner.

I was driving down the road and suddenly lost tons of acceleration power had to almost flour it to move at all so I pulled off the road to stop and check it out. After I stopped I couldn't get it to start again it would crank like it wanted to start but nothing. So I had I towed home and it sat for a little while and then I tried to crank again, and it started and idled like crap and when I pushed down on the gas pedal there was no reaction, rpms didn't go up or nothing but still would idle like crap.
Symptoms stayed the same for about a day and no I have a crank no start. So then I did what little I could do just to see if it was an easy fix I changed the ICP sensor, IPR sensor, and EGR valve needed to be replaced so I replaced that too. Headstuds and gaskets have been done as well by previous owner but not I think it might be an HPOP problem? I am unable to read codes at the moment as well just FYI. Could this be a fuel filter issue even tho the secondary housing fills with diesel?

ok, so after all the work done (headgaskets, head bolts, egr valve, ipr valve, egr cooler, oil cooler, blue spring kit, new ficm injector harness connectors), this is what I'm left with on start up. I am now getting no SYNC -0
I had ficm sync before i changed the connectors on the injector harness (last thing i did besides blue spring kit). Has this motor turn this way? And my glow plug light now comes on during and post crank along with a weird fuel light with 3 teardrops I've never seen before. I need to check this out.

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.

Brother in law company 6.0 died on him in his driveway after a night of plowing
It stalled out, his boss sent out a "tech" and he said it doesn't have "nearly enough" oil pressure
Now I want to further diagnose the truck myself with my scan gauge II but haven't used it for that......yet......
What should I check for IPR pressure psi or %?
I know I can get ICP pressure in PSI on my SCT x4 not sure about the Scan Gauge......
I assume a blown IPR or failed STC fitting......
Truck is a 2005..... I can figure out the scan gauge I just need to know what to look for for an idea of a blown IPR or STC or ICP.

05 6.0 will only start if I cycle the glow plugs, crank 3 seconds shut off glow again then it starts immediately. If I try to glow 2 cycles with out cranking it won't start either. When he truck is hot it seams to start easier. I have new batteries new alternator running 5-40 synth. New glow plug control module. It does it hot or cold weather.

I have a 05 with 100K miles on it. I had the HPOP, FICM and EGR delete do about a year ago. Went to start the truck pressed the pedal and it died and won't start. It dies once while driving about a week ago but restarted. I have a Snap-on scanner for the data. FICM tested good and getting fuel to secondary filter. Batteries and filters are new with about 2K miles on them. Would this data point to a bad IPR?
ICP V KOEO = .25V
ICP V Cranking = .28V

I had a crank no start with very low hpo pressure. I went to do an air test and could not get my IPR valve to do anything with 12 volts applied. I have a switch wired to it, and went as far as wiring the IPR valve directly to the battery and got nothing. This is a brand new ipr valve, never seen a mile of driving, and I'm wondering if my luck could really be bad enough to get a bad one in the box, or if it could be my truck that's frying them. I have cranked on it a lot trying to start, but I have a feeling this IPR is to blame. I'm on my way to get a warranty replacement now. If my truck could frying them, would that be just a bad ground or what? Any way to test my wiring? I have a multimeter...

2004 6.0 truck ran fine parked it, went out next morning and has been a crank no start. Brand new ficm put in today. Also scangauge readings while cranking.
IPR DUTY 30%
ICP -1000+
ICPV-.2 and rises
FICM-49.5 Never drop below 48
FICM LOGIC-11.5V And it also drops to 9 volts cranking
FICM SYNC-Yes
CAM/CRANK SYNC-Yes
I can here fuel pump running and have checked the bowl and fills in 3 second, also have held valve down in oil filter housing and it fills up in 4 seconds. Oil level perfect half tank fuel .. Also I get no smoke from tail pipe while trying to crank. Acts like it not firing or has no fuel... Driving me crazy been working on it for three weeks.

Just installed lots of new parts on this late 04 6 liter HPOP, Stand pipes, nipple cup orings, head gaskets. and now she wont go. Just cranks. Doing an air test now, should I be able to hear anything form the oil fill tube? It builds oil pressure just not right away, I did have an icp code. but has gone away as of now (p2285). What's consider a long crank time?

Ihave a 2008 E 350 6.0 , while driving i hit a small pothole no big deal the van stops running and coasts to the side of the road. get her towed. The dash lights show the PATS is engaged so it is no start no crank.
The 30 amp fuse PCM power relay is blown. when i replace it it blows as soon as i turn the key. im checking for wire chafing but so far have found none.

2003 crank no start, 196k bone stock truck egr still in truck and stock head bolts. Replaced the icp sensor and ipr sensor, both from ford. What happened is I got fuel then about 15 minutes afterwards my truck acted like it was going up a hill and was just losing power and shut itself off. ficm tested 48.5 volts all 8 injectors tested good and there is oil pressure. Had an egr fault code but I'm at a loss.....

So any ICP sensor been proven bad but i was not leaking oil? The symptoms of my truck sound similar to a bad ICP...fluctuating idle, surging, stalling, but it does run and start. IT tends to start acting up when it hits operating temp.
I have an 04 and the ICP sensor is in the easy spot to get to on the valve cover vs under the turbo (that's awesome) so its an easy swap. but just wondering if there is any way to test it over simply swapping it. I do not have a monitor yet but a dongle is on order and will get the torque app for my tablet.

So after updating Sync in my Super Duty the system no longer receives text messages on the stereo. Before the update if I was paying attention I could hit a button on the screen and the stereo would speak the text message. Now all I get is my phone is not blue tooth compatible with the system.

My 2011 6.7L F250 Superduty died on interstate the other night. Picking up throttle pulling onto interstate when a message came on the dash "reducing engine power" and the truck died. It will crank but will not start. It will start on ether but dies when that runs out. Has the following codes... p1249 Wastegate control valve, p0087 fuel rail/system pressure too low, p1291 & p1292 injector high side short to ground or battery (bank 1 & 2), p2291 injector control pressure too low-engine cranking. The codes are telling me I don't have enough fuel pressure but scan tool says I have 4000 w/ key on and 6370 while cranking and I thought 5000 was the pressure needed.

I have a 2004 Excursion with strange symptoms. It will start cold and when you drive it for a while, then turn it off, it will start again right away. If you leave it for an hour you will get a "crank no start". Leave it till the engine cools down completely and it will start again.
The other day it wouldn't start cold, but after I had it towed in to a mechanic, he turned the key and it started right away. I left it with him for 3 days and he could not get it to "not start". So I picked it up and drove it for an hour, parked it and left it for an hour came back and had a "crank no start" till it was cold again. I love my truck but it doesn't seem to like me.
