While it is true a FICM can test good but still be bad, I doubt that's your issue. That is VERY unlikely and I'd suspect it would at least stumble to life and idle like complete garbage. I doubt that's your issue. Without AE on hand, you might have to do a little more work with your hands. When you're cranking the truck, and if it fires, does the oil pressure gauge on the dash come up at all? If it does, I'd start by pulling the IPR valve, it is located behind the turbo, drivers side. It does need a special socket. You can make your own or buy one, but that's where I'd start.

It might also be a good idea to pull the fuel filter out of the housing on top of the engine and turn the key to see if it fills up with fuel. When you first turn the key can you hear/feel the fuel pump running?

 

Best bet if you have the ability is to check what your Oil PSI is. Thatll tell you alot. 6.0s run on oil. Its envolved in everything. Id put air to it as well and see if you have a leak somewhere thats keeping you oil psi from bein high enough. Check the IGR valve. Theres a screen inside it that if clogged or damaged will keep your oil psi from bein high enough

 

My A E scanner arrived today ,had it up and running in about ten minutes, To bad the truck wasnt , A E spit out some codes P 1876 transfer case 2 wheel drive silanoid open short to ground , ,P 1832 transfer case 4 wheel drive silanoid circuit open or short to ground, ,B 1483 brake on/off switch circuit failure,,B 1360 ,ignition switch circuit open ,B 1318,low battery , B 1352, key in circuit fault, u 1900 can communication bus fault ,
truck wants to start,,sputters and stumbles ,,little black smoke .going to check the fuel pump , going to add an in line 5000psi oil filled gauge and see whats up, going to service the IPR also,, any one have an opinion on how and were I should tap in to the fuel line,,, was going to add it to the out port on the fuel filter,some thing to do while I wait for some feed back on the codes ,,thanks

 

Fuel pressure should only be around 65psi. the AE will monitor the ICP desired ad ICP actual when cranking, need to see at least 525psi on the actual for it to fire up

 

Mav, I answered your question and posted the codes on your other thread.

 

I also have an issue with crank no start with my E 350 diesel. I did have some smoke comming out when trying to start. I was able to start the engin on Jan. 03 this year-I let it run for a couple of hours. It will not start now and no smoke is comming out.
I have tried plugging it in to the block heater-charged batteries-used alittle ether-at first I did not hear the fuel pump run-now I think that I do=also have ohmed out the fuses and the relays, they check ok. My Ford Dealer experience with simular situations has been expensive. HELP ! ? D W C

 

No smoke when cranking is either an oil issue or the FICM. Test your FICM and let us know how it tests out. The test procedure is at the top of the 6.0 page.

 

My FICM is on a E 350 and is difficult to remove---I can remove the front side but the back is difficult to access the two allen head bolts. Any suggestions???

You do not need to take it off to test it, it is supposed to stay on the truck, there is a small inspection cover on the top you need to remove to get access to the test points. The thread at the top of the page covers this.
