Suzuki's compact Vitara sport utility vehicle replaced the Suzuki Sidekick. It is available as a four-door wagon with a four-cylinder engine and as a two-door convertible with a shorter wheelbase. There are several reasons why these cars might not start.
Fuel Pressure Regulator Problems
The 1999 through 2001 Suzuki Vitara models were recalled due to a fuel pressure regulator defect. At cold temperatures, moisture can form in the fuel pressure regulator, which can cause fuel leakage and problems starting the engine.
The Suzuki Vitara's engine control unit, or ECU, is manufactured by Mitsubishi Electric. Because of manufacturing and design defects, the ECU has been failing, which will cause the engine to not start.
If any of the spark plug wires are defective or have become loose or disconnected, this will cause the car not to start. Check to see that all plug wires are firmly connected on both ends and are free of damage. Tighten any loose connections and replace the wires if they appear to be defective.
