HI, my 98 wrangler won't start on the first key turn but starts on the 2nd or 3rd, what could it be? I replaced the starter and cleaned battery terminals

. Replace platinum spark plugs with the exact Champion plugs that came in the vehicle, if they have not been replaced in the last 3 years. Only use Champion plugs.

. Check for codes. Crankshaft Position Sensors can cause starting issues.

. Clean throttle plate, throttle body, and Idle Air Control Valve. Afterwards, clean the air box and replace the air filter.
