Hi,

In most cases, a crank no start is the result of either an ignition-related problem or fuel. You mentioned the ignition control circuit above, but I'm not sure what you are referring to. Are you getting spark to the plugs? Have you checked for fuel pressure? Are there diagnostic trouble codes stored?

Let me know.

Hi,

The code could be related to a couple of things. Do me a favor. I attached the diagnostics below specific to the code. Take a look through them and let me know if you are comfortable performing them.

Let me know.

Take care,

Joe
