Hard start no start 05 f450 6.0


The most common concerns on this model are going to be faulty injectors, you can perform a buzz test to check them. The next is high pressure oil system leaks, especially at the STC fitting above the HPOP.

2006 ford f350 deisel turns over wont start unless i use starting fluid it then runs great. changed fuel filter oil filter and oil, wrench symbol came on went into engine fail safe mode, said something...


the diesel engine is a 6.0L or a 6.4L? because the 6.0L don't use electronic throttle control. they control the demand of diesel threw the high pressure oil system they have a sensor call injector pressure regulator. this sensor is responsible of maintain the proper pressure in the high pressure oil system so that the engine could start . i also suggest you to check if it is any leak on the high pressure oil system or if the low pressure system is delivering the pressure required for the high pressure system to work properly. to do that you most have a scan tool. also you can check the pressure of the diesel pump that its in the chassis to eliminate the high pressure oil system as the cause of your concern. if u don't have the proper gauges to check the pressure of the diesel pump you could remove the cap of the small fuel filter that is next to the oil filter remove the filter and put the ignition switch in the on position and see in the container if you have a fast or slow filling. if you encounter that the filling is too slow then your problem is with the fuel diesel pump that is on the chassis this pump is called HFCM, Horizontal Fuel Control Module

2006 f350 super duty diesel start good in the mornings but after is warm it wont start.


these trucks use a oil fired fuel injector, if your high pressure oil pump has eccessive wear or if your oil to broken down from being run to long between oil change, it will not build enough oil pressure to fire the injector once the oil is thinned out from being hot. An oil leak in your high pressure oil system can cause same problem.

High pressure oil pump leak.


the high pressure pump provides the pressure to your injectors so the diesel luel can be injected at high pressure. You should fix this immediately. Call your dealer and ask for some help from Ford on the repair cost ahead of the repair. See what they will do.

Hard Starting


first thing i would check is if your glow plugs are actually any good. next i would check your injectors, then the injector pump make sure it's got the needed pressure. change the fuel filter and reprime the system. if the problem still occurs then look for leaks on the fuel system considering it will start with ether tells me it's somehow losing it's prime.

2006 ford f250 diesel hard to start


The High pressure oil pump is going out.. This is the oil pump that operates your injectors .. when the oil gets hot this oil pump puts out less pressure and will not let the injectors operate right . when the oil is cold in the morning it will have more oil pressure because of the oil stiffness. later after ran a while and it gets warm it wont operate your injectors.. you can also change the oil to a heavier oil but this will only temp fix it.. .. good luck and this is what is wrong with it .. not sure what these cost but they are located at the rear of the engine on top .. on the 6.0 if i remember right not inside the engine.

Ford F-350 Power stroke 6.0 L difficult to start


on both a 7.3l and 6.0l oil pressure is everything. Both engines use two oil pumps one for lubrication and one to fire the injectors. if your high pressure oil pump (inj pump) is weak it will take a long time for the truck to start. In order for the ficm to fire the injectors it wants to see at least 250 - 400 psi of ICP pressure. you will need a scanner to determine your high oil pressure at crank. Let me know how you make out.
