Once you can go Online with the Elite Software Programmer, the next step is to check the various sensors connected.
The easiest to check is the TPS. Move the throttle and check for movement of the TPS signal. Take the opportunity to calibrate your TPS sensor now if it is not calibrated.
If you are using a MAP sensor, then check that the MAP sensor is reading near atmospheric pressure (ignition on, engine not running at this point).
Check Coolant Temp is close to what you would estimate.
Check Air Temp is close to what you would estimate.
Check that the fuel pump primes upon powering on.
