Alright guys, I tried starting the car for the first time yesterday....
Im not getting a bouncing RPM signal while trying to crank the car...
I checked my ignition coil, and its good..I swapped it with another good coil and still no bouncing RPM...
I checked the little gold box beside the coil, and its grounded at the coil....
My coil has 3 wires on it....
-The + side has 1 wire (factory wire)
-The - side has 2 wires (blue/white stripe & black gold box wire)
Can someone help me, and tell me where to start looking?
The only wiring change I made between TBI-->MPI swap, was I cut out the relay tree above the Ignitor (these were all A/C or Alarm related anyway)
Where do I need to start looking guys? Thanks.

Its hard for me to help just because I'm not familiar with how things get set up ecu wise on a setup like yours. Can you describe a little bit of how your setup is wired? I know you didn't wire it but could you describe how for instance your ecu and the msd box interact?
I do know though that the gauges get their rpm signal from the coil like you have it wired. So I guess my first thought would be that your not getting spark or that the ecu isn't correctly wired to your msd box.

Ok sorry, I misunderstood. Can you describe your setup then? I guess I'm not overly versed in all the various ways to set a megasquirt up.

Turns out I had everything wired correctly, but I forgot to plug in the distributor. Stupid me...
Now it's getting a signal.
