Thank you for the response.
There is a switch on this car (only if it has an automatic transmission) called the neutral safety switch. This switch cuts off power from the ignition switch to the starter if the transmission is not in Park or Neutral. It may be that the person who originally installed the remote starter system cut some or all of the wires to the neutral safety switch; because it was not used with the remote starter. After you removed the remote starter; it would be necessary to reconnect the neutral safety switch.
If this vehicle has a manual transmission; there is a switch on the clutch pedal linkage, called the clutch pedal position switch; which cuts power from the ignition switch to the starter unless the clutch pedal is pressed all the way down. If you don't know about this switch, and were not holding the clutch pedal all the way down when trying to start it; this would have kept the starter from working. However; it is likely that this switch was disconnected when the remote starter was installed. If that switch was disconnected; it will have to be hooked up again in order for the starter to work, now that the remote starter is not on the car.
