tricky no start problem..
 
Today I finished installing new transmission, the engine cranks BUT ONLY starts for a sec if i spray starter fluid into throttle body (quickstart) and dies right away. Looks like I have no fuel BUT The most confusing thing is in the fuel rails there is fuel if i press the release nipple.

It started before like clock work, no problems ever before I replaced transmission. it cant be a wiring thing, because I have spark, and NO check engine codes.

How can it be that I have fuel in the rails, and spark and wont start???

Is the trans in the park gear?

it seems the PCM is not sending signal to the injectors, but the injectors do have power.
