having issues starting
ok my neighbor has a 06 6.0 f250 some times it starts some times it wont, and when it does it takes a few seconds i've changed the fuel filters drained the water separator his batteries are good air filter is good and oil is good. I did noticed though when it is cranking and not starting it's not showing any oil pressure is that normal when it wont crank? or does it build when it starts? thanks for your help i will check back tommorrow.

Too many things can cause a no-start condition, so there is no point in shotgunning possible causes without more info. The good news is that an '06 should still be under the engine warranty of 5yr/100kmiles.

A "no-start" condition could be from quite a few things. Here are some discussed
• Shift lever not in park or neutral. Try restarting while slightly moving the gearshift lever.
• Bad fuel - drain the HFCM water separator and inspect fuel.
• Clogged air filter – Inspect the filter minder, then inspect and/or replace filter.
• Air in the fuel - most frequently caused by a bad seal on the HFCM cap (or bad o-ring). Replace o-ring, lube w/ oil and re-install carefully.
• No fuel flow (clogged fuel filter, bad HFCM, clogged pump suction line, etc). First, remove secondary fuel filter, empty fuel from bowl, and then turn the key (don't start) to see if HFCM is filling the upper fuel bowl, Then, change filters or, if possible, check fuel pressure if you don't mind a little work to install a gauge (install one on the secondary fuel bowl sample port). You can also blow air through fuel lines if you think they may be plugged.
• Oil problems (foaming, loss of viscosity: too thick or fuel diluted). Check oil level for fuel dilution, inspect oil condition, maybe even change oil and filter. Definitely make sure you filled w/ the proper oil.
• Bad batteries (coupled w/ bad alternator) or bad starter (needs 500 rpm to start IIRC) - load test each batteries and test alternator.
• Bad ground or corroded terminals/wires. Check battery and charging system wires and cables.
• Bad anti-theft system or remote-start system - disconnect system and see if it starts.
• Bad ICP sensor. The ICP sensor harness can be removed and the PCM will establish a default control scheme that would allow the truck to start if the problem were the ICP sensor.
• Bad glow plugs or module. You can make a cursory check on this system if you have an inductive (clamp on) amp meter (200 A at first dropping quickly to 35-37 A is OK. Both modules should read apprx. the same.
• If possible, you can pull the ICP and install a pressure gauge to check the pressure in the “high pressure oil system”. Crank the engine and watch the pressure. You need 500 psig to start.
More things that could cause a "no-start" condition:
• Injector oil latching (or stiction). New flash from the dealership can often times help.
• A stuck or bad injection pressure regulator (IPR).
• Injector o-ring failure (or other type of injector failure).
• Bad Fuel Injection Control Module (FICM).
• Low base oil pressure (failed oil pressure regulator).
• Low base oil pressure (bad low pressure oil pump - LPOP).
• High pressure oil rail o-ring failure.
• High pressure oil stand pipe o-ring failure or the pipe itself.
• The high pressure oil pump (HPOP) stc fitting (if so equipped - 05's particularly prone to this).
• The high pressure oil branch tube.
• A weak HPOP pump.
• A bad PCM (computer).
• Bad Camshaft or Crankshaft sensor.
• Shift lever not in park or neutral. Try restarting while slightly moving the gearshift lever.

Charge Air Cooler (intercooler) leaks oil or hose blows off, driver's side:
If excessive oil is leaking from the driver's side intercooler to pipe hose, replace the clamps with spring loaded ones which will better accommodate thermal expansion. If the driver's side hose has blown off, replace the tube assembly along with the clamps.

You said 10W-40 oil???? Gas engine oil???
It does not have the anti foaming additives required for the 6.0
If it's not a CJ-4 rated oil (API label on bottle) Change oil immediatly using only a motorcraft oil filter and use a brand name 15W40 diesel motor oil that's rated CJ-4. Wal-Mart has Motorcraft filters and Shell Rotella-T oil. Capacity is 15 quarts.

The 6th item on my list that texans posted - the wrong oil can cause starting issues. Maybe not immediately, but quickly enough.
Also, using a 10W40 (any non-diesel oil) will cause a lot more problems than just a no-start.
