FORD: 6.0 DIESEL..WONT START..A HOT RESTART WILL START AFTER COOL

This answer was rated:

2006 6.0 DIESEL FORD WONT START ON A HOT RESTART WILL START AFTER COOL DOWN. HAS NEW ICP, IPR,AND FUEL RELAY. WE ARE LOOKING FOR A FUEL INJECTION PUMP SOLENOID, UNABLE TO LOCATE THE COMPONENT? ANY SUGGESTIONS?
Customer/p>

What you are experiencing is a common problem with the later 6.0l engines,there is a quick connect fitting from the high pressure oil pump the oil rail feed tubes,this connector fails and will blow apart and cause a no start condition. They will sometimes start after cool down whe the oil gets thick enough to build pressure and overcome the leak. Ford has a repair kit to correct this problem. If your unit has under 100,000 mi

it should still be covered under warranty.

we are aware of this bulletin, but this truck starts every time it cools down. Not sometimes as you said in your answer. We just want to be sure before we go there. Our truck has 169042 miles on it (ambulance). Joe
I am 100% sure that is your problem,I would get it in and have it repaired right away,if not,the fitting will keep flexing and will eventually crack the branch tubes,if that happens the engine will have to be removed to replace them.These fittings will come apart just enough to create a no start hot but will allow enough ICP pressure to build when cold to start.

Okay, we have the vehicle and we will call ford to see if they have the parts. Do you by any chance have the breakdown on how to get to this fitting? If not we will see if ford or alldata has the information. Joe
