Won't turnover in cold ?
Team,
need your help asap please.
10/24 @ 6am 45° my lexus wouldn't start up. It cranked, started, shutoff all in 2 secs.... I first thought it was the key pad. Tried other one and it started. Changed both key pad batteries. Drove rest of week fine...
10/30 @ 7am same thing around 40° Called AAA. Before he got here, it started right up around 57° . They told me weak battery. So I replaced it.
11/5 @ 6am same thing around 40° crank start stop. wouldn't start just crank at 32°. Waited 1 min and started right up....
12/10 @ 5am 28° cranked. Started up , rev to 2krpm. Shutoff... I tried to start all it does is crank ,but won't turn over. Pedal real stiff too... wait few seconds pedal move but still no start up. Cranks fast not like dead battery. Has 700cca 850ca. Battery good. Keypad good. What could it be?
ideas: battery (replaced) ; colant temp sensor,

The sensor is not expensive, just kind of tight to get to it.

From what you explained it seems like the cars not getting fuel. From what you explained to us it turns over normally just doesn't fire on and does not show codes. Many have experienced these issues of intermittent starting, they would either disconnect and reconnect the plug and the car would start.

Update: took to dealer. They said it's code: B2784 Certification ECU. - Smart key system. Antenna Coil Open / Short. Its either the engine switch ($300) or Certification ECU ($1100) Plus $300 for diagnosis & labor.
