What causes a Lexus not to Start?
The most common causes that hinders normal starting operation of your Lexus IS350 are dead key fob battery, dead 12v battery, corrosion on battery terminals, bad alternator, clogged fuel filter, broken starter, blown fuse, empty gas tank, immobilizer error or any fault in the electrical system.
Why is my alternator not working in my Lexus?
With the headlights, blower motor, and radio on this should change very little. If the voltages begin to drop into the low 13 volts or below (usually rapidly as the loads increase), a failing alternator is to blame. Seen above is a factory re-manufactured alternator next to a failing unit removed from a 1998 GS400.
Can a faulty starter cause a Lexus to not start?
Faulty starter is rare, but due to the aging process, its very common problem for the first generation 1UZFE cars. This article is intended to rule out starter problem. It’s much easier to change other parts associated with starter, then changing the starter itself.
