03 6.0 crank no start with data

Hey guys,

So I was having a stalling no start hot condition and figured it was a clogged IPR screen. Pulled the IPR today and found no screen on the end, replaced the O-rings, seals, and screen with OEM. and also backlashed the valve with carb cleaner. Follow DTR's procedure and removed the injector harness and such to make as much room as I could. Got it put back together and now I have a crank no start. It started and ran last night.

ICP 1500
IPR 51.1%
SYC 1
FMP 47.5 (while cranking)
FLP 9.5 (Im thinking this is my issue) But i have no idea what would cause this.
Bat volt 11.5


Charged batteries in readings are:

ICP tops out at 1700
IPR 70%
RPM 450
FLP 12v drops to 11 when cranking
FMP 47.5



it cranks at speed and chugs like it trying to fire but just won't light off.

I have double checked all my connections are good and seated... Any ideas?

Is 11.5 volts your cranking voltage?
Can you post the cranking ICP voltage?

I would sure like to see an actual cranking rpm number. I hate going off of the "sound" when a number is so easy ton get.

Sounds like your FICM may need to be rebuilt.

Edit - I see you later added the rpm number. That is good to include ....

It was cranking around 300Rpm on the scan gauge.
ICP voltage KOEO was .23v

no 11.5v was KOEO as well

I ended up cranking it enough that the batteries were causing an audible slow crank so I just dropped them off to have them charged. Ill pick them up in an hour or so and then be able to run more tests.

11.5 KOEO is a dead battery but you say its cranking normally. So you've got a boogy connection somewhere which could very well have nothing to do with your no-start but you should at least clean up all the battery connections.

It was, I took he batteries to have them charged and it brought the FLP up tp 12v static and 11v cranking

12V static FLV is low also. It should be at battery voltage and static voltage should be at least 12.6v. Did you get them load tested? That said, 11V cranking isn't bad ..... if it stays there during the troubleshooting.

Do you have access to a good code reader? The scangauge is a VERY poor code reader.
How about verifying fuel flow to the upper filter w/ just the key on and filter housing cap off?

Is your SYC reading for FICM sync or cam/crank sync.? It would be good to see both.

I still would like to see ICP sensor voltage when cranking.

I have a good code reader but it isn't throwing a code.

SYC is FICM SYC. I don't know the PID for cam crank SYC. it was my understanding that if the cam and crank are good I will have SYC for FICM.

The batteries are brand new and were load tested and passed.

I have not checked the fuel flow but I will go do that now.

If you don't mind me asking .... what are you using for a code reader?

You won't get FICM sync without having cam/crank sync, but you can have cam/crank sync and not have FICM sync. A lot of people get the programming backwards for the sync PIDs on the scangauge.

Its an Innova Scan, it will run the ford enhanced KOEO and KOER tests.

Usually the scangauge PID for cam/crank sync is labelled "SYC" and the FICM sync is labeled "FSN".

The FICM Sync "RXD" parameter is 3601

Checked fuel flow the upper bowl filled fast.

I went and bought a cheap inspection camera today and this weekend ill pull the IPR out again and check the bore again for the missing screen.

I checked when I replaced the valve with a pick and didn't feel anything but if its there im thinking it might be locking HPO flow.

Aside from that im kinda stuck, This was the only area I was messing around in and it ran before.

The no start cold has been solved, the previous IPR screen was still in the bore.

I still have a no start hot issue but it now runs again and I'm thinking its stand pipes and dummy plugs

Why was your ICP as high as 1700 during the no start? That is WAY more pressure than you need to start. IMO it is most likely a bad sensor .... and your ICP values (1500 and 1700) were default values. That is why I asked for the cranking ICP voltage. I have the correlations between sensor voltage and pressure. 0.23v is good for KOEO, but the high pressures when cranking don't make sense.

So the old IPR screen was still in the hole so I had great pressure but severely restricted flow (probably causing the extremely high pressure) through the IPR passage and Im assuming the IPR, while snugged against the surface of the HPOP cover, was blocked as well based on the paths I saw on the inspection camera.

Once I pulled the old screen out and replaced everything it fired right up and ran well until I shut it off after it got to operating temp. After I had a crank no start hot.

I don't know if I buy that. Anything limiting flow to the injectors will also cause reduced pressure AT the injectors.

Not only that, but the IPR duty cycle (which is ONLY a commanded value and not and actual valve position) is high meaning the computer wants more pressure.
