July 25, 2011Was talking to a friend of mine the other day and he has a Ford truck with the 6.0 diesel in it. He said the truck starts fine when it is cold. After it warms up it will turn over but not start. Anyone have any ideas what it may be? Thanks.

July 25, 2011it is a fuel feed problem at the HPOP. i want to say the elbow going into it, but am not sure if that is it or not.
if you have a good diesel shop or a good diesel dealer in your area, they will know what is needed to fix it.
July 25, 2011I am totally illiterate on diesels. What is the HPOP?
July 25, 2011HPOP = High Pressure Oil Pump - It ups the pressure in the oil lines to the injectors. High Pressure oil helps the injectors squirt the fuel into the cylinders.
Another thing to look at is the FICM (Fuel Injection Control Module) - It is supposed to be reading around 48V. Now....I have a 7.3L. The information I am giving you is based on what I`ve read over on http://www.powerstrok... If the voltage drops below that level, it could be causing a no-start situation. Unfortunately, I don`t know what you do to test the voltage.

August 31, 2011I am picking mine up tomorrow. It is@ the dealer for a no-start issue too.
It turned out to be exactly what the other post said here...FICM was bad & had an HPOP leak...
September 1, 20117.3 and 6.0 are different. when a 7.3 has a no start it is usually the ficm. when a 6.0 has a hot no start it is a hpop leak.
July 14, 2012I know this is old, and this information will more than likely not help your sitiuation. But
You had a high pressure oil leak, they are common and the STC(snap to connect fitting) at the HPOP(high pressure oil pump, under the turbo in the vally) or the "dummy plug" on the front of the high pressure oil rail, the vehicle has two of them on for each side, In order to test this you have to remove the ICP sensor (injection control pressure sensor, passenger side valve cover towards the front) and install a air fittting to supply 150psi aprox air prssure to hear and air leak.
A FICM (Fuel Injection Control Modual) can also cause a no start concern but they are more than likely gonna have a "fuel clap" it is still gonna supply the cylinders and will try to start but will more than likely not. Also the FICM normally has a no start cold not a no start hot concern. The FICM volts should not drop below 45volts (not 48 as priviusly said, if 48 was the rule all ficms would be bad.)
