Crank no start, HPOP?

[thedjwcc]

Hey guys,

Ive been trying to research the problem for a couple of hours now, havent came to any definate solutions yet, figured I would ask for help.

I have a 2006 with the 6.0L with a crank no start problem.

My research has led me to believe that it may be the HPOP. When you crank on it the oil pressure guage stays at 0, or dosent move. Would this be a symptom of a HPOP? Is there any other way to test the HPOP before diving that deep into it?

Ive also heard problems with the IPR(?). Havent been able to understand exactly what or where this is and how to test it.

I found out how to test the FICM and may do this to start off with.

What other ideas would do you have that i should check for.
It dosent smell or act like its getting any fuel to the cylinders.

Thank you.

It takes 7psi of base oil pressure to move the oil pressure gauge. Do you have an oil leak in the front cover where the pump may have broke. Have you checked oil level? Any DTCs stored in the computer? Do you have aftermarket or OEM oil filter? You can remove the oil filter press the valve in the bottom with screw driver and see if you have base oil pressure building. Just some ideas to get started.

FICM was good

No oil leak near the pump

Plenty of oil

New filter

Took the filter out and cranked on it, It begings to fill with oil slowly, not sure what that means though.

Not sure about the DTCs

Unplugged the thing(ICP,IPR?) by the pump and cranked but still nothing. I read in some threads that means it may be bad. No pressure or fire. Should I procede to HPOP digging?

You need to get a monitor on there that will show the ICP pressure while cranking if its under 500 psi your engine will not fire.

What grade oil are you using. When you pulled out the oil filter was there oil in the housing? I use 10w30 in all 6.0L it's what they came out of the factory with. If your oil is flowing slow on low pressure side then you won't be able to fill the high pressure side to fire your injectors. I would try and find a way to read generic DTCs that will give a good starting point. What was the vehicle doing before it wouldn't start? Was any maintenance just performed?

Fam that is wrong info they came from the factory with motorcraft 15w-40 oil.

This may sound funny but i had my oil changed and they didnt put a motorcraft oil filter back in and a couple of days later my truck died with 0 oil pressure. It wasnt working that valve in the bottom of the oil filter housing right. New motorcraft oil filter and it fired right up and ran perfect. 2005 f-350 king ranch

one more thing. I replaced the valave in the bottom of the oil filter hosing as well. It was broke from the wrong oil filter. The after market filter was shorter than the OEM.

I plugged in a bully dog monitor and was getting 0 ICP pressure reading. The oil pressure started to build to the midway point on the guage during crank now, i think maybe the battries just werent charged up enough and are bad. The DTCs didnt show anything on it. Im not really sure about the maintenance, I bought it off of a guy that was in a pinch for some cash and was practially giving it away. He said he didnt have the money to fix it.
