Won't start

The Best V8 Stories One Small Block at Time
So far i have:
-battery voltage
-crossed terminals on the starter and it does spin
-checked all ground connections to see if they are attached (i counted 5 total, 1 above oil pan in front, 2 on a bellhousing bolt, 2 bolted to the transmission towards the drivers side)
-checked continuity of the s-wire (purple) going to the starter
-checked starter fuse and relay
-checked all the connections that i had disconnected
Any ideas or things I should look at?
Also, with the key in the on position, should the indicated gear show up? The car owner says no, but he hasn't driven the car in months.
YES!
recheck the transmission range switch and the VSS sensor also make sure the batt terminals are tight and the body ground at the batt, if you can turn them they are not tight.
Is it your original TCM? Did you remove it?
Yes the gearshift indicator should show it does in my 06 and in my neighbors 07.
Check all your fuses and double check that everything is tight in the fuse box.
Also a more likely secanrio is the manual shaft detent lever maybe your problem.




Go here: http://www.gmls4.com/index.php?topic=1412.0 and find G111 and with your meter test from the mount of G111 to the appropriate connector pins @ (trans internal mode K-bk/wh, starter relay bk/wh, TCM 49 bk/wh) If I remember correctly the starter relay is the same as the fuel pump relay, swap and verify them as functional.
I will post some info here in a bit (not near my scanner at the moment)
