This for sure looks to be a fuel pressure issue but with the high pressure side. Do you have a scan tool that can show pressure actual and desired while in a crank no start state?

I like to stay in contact with my customers that appear not pleased, still working on the concern, or have not rated yet. I assume you were not pleased with my help. I hate that you have spent money to get an answer but left not happy. Can you tell me why, or can I help more. If its more help you need just reply and we can pick up where we left off.

Thanks Chris
