Gas No Crank No Start 2011 2016 Ford F250 Super Duty Forum In relatively older cars, roughly those made before 2005, a bad ecu doesn’t cause the engine to not crank. it certainly will prevent the engine from starting, but you can still crank. in newer cars, the engine won’t crank if the ecu is faulty because a lot of safety systems run through it that prevent you from cranking the engine. 2. bad fuse, main relay, fuel pump or other relay. the fuel pump relay or fuse or main relay (module) failures are common in some vehicles. in many honda cars, a failed pgm fi main relay could cause a car not to start. in some chrysler and dodge vehicles, a bad asd relay was often responsible for a no start. 6.7l power stroke diesel. 6.4l power stroke diesel. 6.0l power stroke diesel. 1999 2003 7.3l power stroke diesel. 1994.5 1997 7.3l power stroke diesel. pre power stroke diesel (7.3l idi & 6.9l) bio diesel, propane & alternative diesel engine fuels. competition. small chassis trucks. One of the most common causes of a 6.0l "no start when hot" is a leak in the high pressure oil system. the best way to identify this is to post the cranking icp sensor pressure, the icp voltage, and the ipr % duty cycle. it is best to retrieve this data when you are getting the no start (ie when hot). more on this below.
