How to diagnose and repair the 6.0L Powerstroke crank no start

The 6.0L Powerstroke crank is a good engine and can be dependable, just like other Ford Powerstroke diesel engines. It does not make so much noise and has modern-day emission standards. Above all, it is a winner when it comes to drivability. But here is the rub. The engine operates on high oil pressures that can result in oil leaks and other technical issues. So what do you do when your Ford 6.0L Powerstroke runs into a problem? In this guide, I will walk you through the whole process of troubleshooting a 6.0L Powerstroke crank no start.

6.0L Powerstroke crank no start diagnostic tips

The first step to start troubleshooting a 6.0L Powerstroke is to figure out the root cause of the problem. What this means is this. You should be able to lay your fingers on what causes the no-start problem in the engine.

Warning: At times, several factors can come together to disrupt the performance of the engine.

With a few years of experience in troubleshooting a no-start issue in the 6.0L Powerstroke cranks no start, I have been able to gather a few diagnostic tips. I believed you would find them helpful in troubleshooting the Ford 6.0L Powerstroke no start.

  1. Check the starter relay connections: Wiring problems are among the many problems your engine has refused to kick start. To confirm if it is a wiring problem, disconnect the light blue stripe colored wire under the hood and adjacent to the passenger side battery near the squeeze-and-pull type connection. After disconnecting the wire, connect the main end of the connector to the positive terminal of the passenger side battery. The starter should crank during the test, or there is a wiring problem.
  2. Inspect the EGR valve because the 6.0L Powerstroke engine will encounter a starting problem if the EGR is dirty or damaged.
  3. Check the ICP sensor: A damaged ICP sensor also contributes to a no-start problem in the engine. Also, watch out for the ICP circuit fuse.
  4. The ignition switch and the starter: Another diagnostic check to run when having a nose start issue is to check the ignition switch and the starter. If the parts are not working properly, the engine will have a problem engaging the starter.
  5. Plug and battery connections: Are all the battery connections secured, including the ground connections? Also, are the plug connectors having a secured connection?
  6. Low battery voltage: To start a 6.0L Powerstroke, you will need about 180 to 200 rpm cracking speed. If the battery voltage does not fall within this range, you will have difficulty getting the engine to kick start.
  7. Oil level: There will be a no-start condition if the engine oil level is below the required oil level to build fuel pressure. Always remember that the 6.0L Powerstroke will need a high-pressure oil circuit for building its fuel pressure.
  8. Fuel quality: an engine with excess water in the fuel will cause damage to the injectors and usually results in a no-start condition. What I do in this situation is to drain the excess water in the fuel tank from time to time.
