03 No Start, Basics, FICM CK'd Auto E info posted.


03 6.0 F250 CC 4wd Auto.

Truck turns over, but won't start.

Symptions: Reduced power on way to work, limp mode going home. Towed to small dealership (MISTAKE) 3 weeks later diagnosis is new short block and wiring harness and 12K

Have already completed BISMIC's "Troubleshooting a No-Start Condition Steps 1-26.

FICM Voltage Test on 7 screw unit.

Test 1. Step 4b 48Vdc.
Test 2. Step 5b 47Vdc during initial buzz test, Voltage drops to 40 then back to 48 as cycle completes.
Test 3. Step 6b 46Vdc.

Auto Enginuity Readings During Long Crank. Oil Pressure showing on dash gauge.

ICP V.....................0.81..........FICM_L........ .........10.5
ICP Psi..................535...........FICM_M......... .......48
ICP Desired..........1579.........FICM_V.............. ..11.0
ICP Regulato........84.77........FICM_Sync...........1
RPM......................180...........CPS&CKM Sync.....1
Injector Timing......5.5

Tech at dealership said that there is high and low oil pressure present as checked by test port gauge. Nominal Fuel pressure, it's just not getting a signal to start.
Said that the Camshaft timing Pin is coming out as evidenced by wear on CMP sensor and borescope inspection of timing pin showing wear. CMP Sensor R&R'd

The ICP V look's to me like the next area to look as the range is 0 - 5Vdc.

Any input is greatly appreciated as I am now 5 weeks w/o truck and Momma does not like me driving her baby ;-)

Thanks in Advance.

Eric

535psi icp is border line enough to start, but by looking at icp desired its asking for 1500psi plus and your ipr is maxed out at 84%. you either have a high pressure oil leak or and failing/weak pump. being an 03 my money is on a pump.

I agree.

After reviewing the paramenters I posted and reading and learning more about AutoEnginuity, I am re-running the test and will post a graph.

I have a second vehicle that I can use to supply additional power to the batteries to keep voltage up to allow cranking for a good 30-40 sec so the graph will show exactly what is happening.

I will also start recording before I start to crank to see info as it builds and end recording after I stop cranking.

Since graps cover 4 items the PIDS will be.

FICM-M, FICM-V, FICM-L, FICM-SYNC.

ICP-V, ICP-PSI, ICP-DESIRED, ICP-DUTY CYCLE

FUEL-PW, CPS CKM-SYNC, RPM, V-BATT

I hope to get to this evening if we don't work to late, if not it will be sunday as tommorrow looks like a 20 hr day.

Truck spent three weeks at a small dealership with a nice young deisel tech, the only guy in the shop. He always had 5 to 7 trucks in there at one time. Admitted that he went after all the easy stuff first.

Hooked up a supposedly known good FICM
R&R Exhause pressure sensor
Removed turbo to check hpop, said it was good
Oil pressure gauges showed good High and Low pressure
Fuel pressure gauge showed good pressure
loosened / removed glow plugs to see it diesel was injecting, saw mist
removed oil pan to check that crankshaft timing wheel was in place, it was
noticed fine metal particles on upper oil pan and remembered that camshaft sensor showed wear.
Borescope inspection showed scoring on camshaft timing pin.

Diagnosis:
Camshaft timing pin is loose and no sync.
Need small block and wiring harness 12K out of my pocket.

I think he got frustrated.

How did check/verify the HPOP was good? BTW, your FICM is low and requires either fixing or replacement. In addition, your batteries are VERY weak and low battery voltage will cause some very erroneous readings by the PCM, causing some "phantom" issues. I would fix some of these "easy" issues prior to throwing in the towel and deciding that the engine needs replacement.

PS. your graphs are showing that your are getting sync between cam and crankshaft, so I would suspect that your problem lies elsewhere.

Do me a favor and get some good batteries in there, disconnect your ICP and try to fire up your truck. If it idles, you have a bad ICP; if not, I would lean strongly to the HPOP as the culprit.

OK: Hang in there with me. I am looking at forced overtime for the next 2 weeks including Sunday's.

Batteries are new, charger hooked up and another vehicle will be inline the next time I try to start.

1. Going to remove the FICM and reflow / resolder all points as called out in
DR.QUADS " FIX ur FICM " then try to start.

2. Next, will get down to ICP and re-locate, then remove plug and try to
start. From what I can see in an 03, the turbo has to come off before
you can access the ICP plug so might as well relocate it.

Any additional thoughts welcome.

You can't relocate it and the turbo doesn't have to be removed to replace it. Hard to get to but can be done.
