Ok here's my latest progress report on my no start issue.

In between the rain storms over the last several days I stripped down the engine to get to the fuel rails and injectors. Pulled everything apart and only broke 1 bolt for the fuel rail mount to the intake manifold and broke 1 fuel injector retention clip.

After pulling the rails and injectors I tested flow thru the fuel supply lines and have no issues there. I flushed out the fuel rails and found no debris and they are clean as a whistle. Injectors were typical dirty on the exterior so I cleaned them well and then pulsed them with a 9v battery and confirmed opening from the power signal. I then hooked up a rig to be able to flush cleaner thru the injector while pulsing with power. All 6 injectors flowed great without much debris at all. Today I will reverse backflush them while I wait for the new seal kits to arrive to begin the reinstall.

I feel good about the current injector condition but uncomfortable about what role if any they played in the no start since they seem clean and have such good flow without any apparent hesitation or difficulty. I think I would feel better if at least a few seemed to be clogged and had poor flow at the start of testing and cleaning them. I guess I'll know better once I reinstall everything and attempt to fire it up.

While everything is stripped down and I have good access I'm using my fiber optic camera to inspect the backside of the engine for all the connections and vacuum hose and anything else I may want to fix or change out while I have clear access to top side

I'll post another update once I put it all back together and see what happens. If anyone has any suggestions of something else to check or test while Im at this stage please shoot me your ideas.
