![]() ![]() Since this is a Ford 6.0 HUEI (Hydraulic Unit Electronic Injector) engine, the scan tool data needed will be the three voltages from the Fuel Injection Control Module (FICM), sync, FICM sync, Injector Control Pressure (ICP) voltage, RPM, Injector Pressure Regulator (IPR) percentage and fuel injector pulse width. In this case, there were no DTC’s stored to aid in a direction. I always take a look to see if there are any stored diagnostic trouble codes. This is so I can gather a lot of information very quickly and since we are working on an electronic diesel, the information I need can be gotten very easily. At this point, I want to see some scan data while cranking to get a direction on this problem.įor no starts/hard start problems, I will always start my testing with a scan tool. While cranking, the engine will fire once in a while in an attempt to start and a little blue smoke comes from the exhaust, but that is about all that happens. Don’t you just love those dime-store tools that make the vehicle owners feel good? Well, in a case like this where the engine will crank but not start, any codes that might have been stored are not of much value to me anyway. They stated the Check Engine light came on and he had cleared the codes with his pocket code reader. The owner states it started running rough and lost power. The complaint on this vehicle is a no start. When being confronted with problems like this, whether you are working on a Ford or any other diesel engine, start with the basics and go from there. Yes, this is a medium-duty truck, although the engine and transmission are the same as any 2005 F-250 that drives up and down the street. ![]() The truck has a six-speed manual transmission with a four-wheel drive powertrain. Today in the shop is a 2005 F-550, with 77,000 miles on the odometer. The vehicle is powered with the 6.0L Diesel engine. ![]() Since the inception of the “electronic diesel” engine, the diagnostic path is a little different compared to an older mechanical engine, but the same questions must still be asked - is the engine cranking fast enough, is there proper compression in the cylinders, is the proper amount of fuel being injected into the cylinder and are the glow plugs working properly for the engine to start? In this article I will lead you through the diagnostic process for a cranks/no start that I have used many times over the years.Ģ005 Ford F550, manual transmission 4 Wheel drive drivetrain with a manual transmission. ![]()
