99 DIYPNP - Starting Failure
I'm trying to get my car to start with my DIYPNP; I've calibrated all the sensors and gotten all the connections sorted out properly, but I can't figure out why the motor isn't cranking.
The starter isn't turning and the coils aren't firing. The fuel pump is working (I can hear it when I turn the key to the on position).
I attached the tune that's currently loaded and a log of when I try to start it a few times.
I probably overlooked something getting everything set up, but if someone could take a look at those and let me know if they see something I could fix, that would be awesome

The starter is driven directly by the ignition switch. There is *NO* ECU control of the starter motor. You need to look at things like battery, clutch safety switch, ignition switch, starter solenoid, and associated wiring.

One of the wiring harness connections wasn't completely connected, so I'm fairly certain that was the reason behind the motor not cranking.
So...I got the motor to crank, but it just wouldn't turn over completely. I ran a log of the motor cranking, if anyone wants to take a look, I'm not really sure what I should be looking for at this point as to what needs adjustment in order for it to hold a steady idle.

What's going on in the log you posted? From the looks of the log, you cranked the car and got it running, then had to keep revving it to keep it running before it died?
I'm probably the last guy you want to take advise from, but if it was me, I'd back the idle screw on the throttle body off a few turns and see if you can give the motor enough air that it will at least hold an idle. Do you have a wideband set up on it? What wideband? Maybe it's just my default settings (AEM wideband) but it looks terribly rich. If that's the case you may want to bring down the Req Fuel settings in Megatune to lean it out a bit.
