Yes, mouthwash or other common substances that contain alcohol will affect the test. Allow sufficient time for the alcohol to dissipate from your mouth to avoid a FAIL test result.
The interlock will enter a temporary lock out period of a few minutes for the first failed BAC test and a longer lock out for any subsequent failed BAC tests. This permits an opportunity for the alcohol to dissipate from the mouth and for the participant to consider the reason for the failed BAC test.
No, current devices have technology such as voice-tone monitoring or temperature gauges which cause the interlock to abort artificial breath samples.
Starting the car in some way other than blowing into the device, is an additional suspension of driving privileges.

The ignition interlock is the most effective tool for combating alcohol impaired driving. Many DUI/DWI offenders choose to drive illegally with a suspended or revoked license. The ignition interlock provides a control mechanism to keep drivers from driving intoxicated. With the use of interlocks more lives will be saved, serious injuries can be greatly reduced, and roadways will be safer. According to MADD, studies have shown that the devices are up to 90 percent effective in keeping convicted drunk drivers from recommitting the crime, as long as installed on the vehicle. Decreasing recidivism, the re-arrest of an offender who has completed the interlock program and regained unrestricted driving privileges, is a primary goal of the interlock program.
Alcohol ignition interlocks are required to meet standards established by the National Highway Traffic Safety Administration (NHTSA). The NHTSA standards ensure the device is reliable and are tested by independent laboratories.

If your license was suspended because of a DUI/DWI offense, the court may require you to get an ignition interlock device to fully restore your driving privileges.
