Default MS not starting car...

The MS I bought was on a 97 and my car is a 99. I did the CAS installation and the MS was run parallel before, and it is run parallel now. I was bored yesterday and just wanted to see if my car would start up, so anyway I plugged it in and turned the key, and it just cranked and cranked. Then I remembered I forgot to plug in my CAS connector. So I did that an tried it again, and still nothing...just cranked and cranked. Then I plugged the stock computer back in and it wouldn't start right away cause it was flooded out real bad. So my theory for the MS is either it flooded cause the injectors were working, but the MS had no timing signal until I remembered to plug it in...OR I wired my CAS wrong. I guess the only way I can check that is with a laptop connected to the MS during the turn key episode?

Hook up a laptop and run megatune. Turn it over and see if you're getting an RPM reading. Look at the guages in megatune. Set one for "pulse width" and see if it's firing the injectors. Verify you are getting spark on all 4 cylinders. If it skips, sputters, backfires, etc while cranking but never cranks and runs, odds are the outputs for the coils are swapped backwards. Just uplug the two connectors that go to the coilpacks and switch them. But now you'll have to switch them back if you try to run on the stock ECU.
