Yes fuel pressure 50psi and holds well when turn key off. Truck will not hit on starting fluid
I think I am missing a starting sequence input, what controls or influences the startup ignition timing. This is the third time this no start condition has occurred in 2 weeks. After the third time it has refused to start. On the 2 prior times once it started the next day the other a few hours later. I did not do anything to the truck the first and second time but check for codes(there were none), confirm fuel pressure, and confirm spark. The truck just started when it was ready. I will check the cat and let you know in about 45min., but I suspect an electrical issue that I am missing.
Ok, pulled o2 on both banks upstream of converter still no start
