Welcome, I'm Chris (aka Moose) I prefer to work when others don't, I am here around lunch and after dinner till after midnight.
When trying to start does it crank slow?
Is there exhaust smoke briefly after startup?
Must you do this every time started hot or cold?
So you have confirmed there is no injector pulse when tested with a noid light when cranking the engine?
Will it start at full throttle with out the spray?
No pulse means your computer is not getting a CMP signal at cranking speed. For some reason the engine has to be going faster for the CMP starts reading. I would replace the cam sensor and sand the mounting surface to make sure it is as close to the timing gear as possible.

Hello again Chris here,
Thanks for letting me know. I have never heard of no injector pulse from a TP sensor and this engine to not have a cam sensor.
