car cranks, no tach signal on Megatune
 

So I finally got everything straightened out and now my computer can read from the MS. I turn the key and it cranks and cranks, but I am getting no tach signal on Megatune. I'm sure it's getting fuel though, cause I turned the ignition off, and then I turned it on again, and it popped out the exhaust. Why would that happen if it didn't even crank over? My AFR on Megatune says like 4.80 which would mean super rich, but my G3 gauge in the LC-1 shows like 10.5? This is a MS-1 3.0 that was run in parallel on a 97, and now I retrofitted it to my 99. I loaded this...MSPNP_MM9697_Base_Map_012808.msq from http://www.megasquirtpnp.com/mspnp_downloads.htm.
My CAS came from Flyin Miata Salvage.
Any advice or suggestions are always helpful guys!

If my CKP and CMP wires are backwards, would I get no signal on Megatune? But would the injectors still fire? It's gotta be something so stupid and simple....
