Back on topic..... The one thing that I forgot to mention was that while I was cranking at the bottom of the screen in tunerstudio it would say "not cranking" until I let go of the key, then I would see it change to red and say "cranking" for a split second then change back to "not cranking".
I'm not sure if that is typical, or if it's an indication of a problem?
I also just realized that I had forgotten to hook up the vacuum line to the MAP sensor in the ecu. I'm not sure if that would cause a starting problem in any way (i.e. the unit is looking for vacuum while cranking or something)?
Yes, vacuum line would effect things, but not as much as cranking RPM. Whatever RPM you crank at (mines around 210rpm) you need to set Cranking RPM about 100 higher than what you see. If its set too low, then the vehicle doesn't see the engine as cranking and doesn't apply startup enrichment, etc.
What software are you using.. Tunerstudio I hope? I'd recommend buying the registered version and doing a crank position sensor log from the Diagnostics tab (composite log and tooth log). That will ensure you're seeing a stable and correct crank signal.
Then ensure you're seeing spark with the tried and true "pull the plug and look for spark" method.

Report back, good luck!!
Yeah I'm using Tunersturdio. I don't think you need the registered version to use the composite log and tooth log. I have the free one and have access to the diagnostics tab. I even data logged a composite log while I was cranking and saved it to a file. I need to pull it off the laptop I was using though. Do I view it with megalogviewer?
It is quite good. I typically do a log, then have MLV (which I also bought, though its not as crippled) analyze it, new tune and repeat, but for cruise and light throttle stuff the VEAL can't be beat.
I pulled those couple logs I made just to check them out. Apparently I'm not getting an rpm signal except for right when I let go of the key which is when I saw the "not cranking" box change to red and say "cranking". I also opened the tooth log and plotted it. I'm not sure how to interpret it though except that those 0 points are where the marks on the wheel are and the log software did pick up those positions because they were highlighted in the log.
