it does. It reads the value just as it does for stock. I did notice however that it's reading it as a hot start or that the coolant is above a certain temperature... but that might be because I forgot to hook up a specific sensor. I'll double check that today as well.

How long has the total run time been now?

maybe... 20-30 seconds give or take.
I keep coming back to a fueling issue, but I just don't see how that is possible especially. The injectors were cleaned and flow tested. I believe I heard the high-pitched tap of their operation while cranking. They have the right size in there and are trimmed to be 460cc/min during operation and starting. I have fuel pressure.
Which leads me back to spark... but the engine kicks on for a second or two on the vapors of the starter fluid, not the actual fluid getting into the combustion chamber. I'm planning on pulling the plugs today and testing for spark on all four. see how it works out.
Still haven't gotten my compression tester back from the guy I lent it too, so I can't give accurate numbers, but I have reason to suspect that the map reading is actually low. While just cranking, not actually starting, the engine produced enough vacuum to surprise me how much air it sucks in while cranking (enough to create a big force to pull my hand away while it was cranking--feels much more than 10inHg, almost like a shop vac)
My problem has to be with one of those 3, otherwise it would be starting and running. Sigh, is there any "easy" way to see if the injectors are putting fuel into the engine?
