I have a problem with the transmission. When I try to start the engine, the electric motor starts to rotate and I hear it, but the gasoline engine does not start. It takes about 10 seconds and it turns off. I checked everything fuel pressure 6psi. I checked all the fuses and the relay ,I restored the hybrid battery. I have no trouble code and I have new 12v battery. I climbed under the car trying to see if the flywheel rotates when I try to start the car, but as I saw it doesn’t spin, I can hear how the electric motor works.
I don t have idea what wrong now.

Well STOP restarting it you will kill the hybrid battery

if you are only getting 6PSI at the fuel pump it's DEAD

what is the check engine light code ?? you clearly do have one as the Check engine light is on after starting as it turns off when cranking

I have a hybrid also ( so you cant' say it does not)

it's staying on when you are cranking the engine at 0:17

should be 50-65 PSI or so





Tell us the code buy a code reader that works yours clearly is broken

Sorry yes I have 60psi
So don't worry about my battery because I'm used Tech2 scan tool and charge my battery use Jump assist mode
My Tech2 not found any trouble code.

well have you tired starting it with the remote?

but you have one though as the CEL is on


are you getting spark??

does it sound like the engine is spinning?... is the crank shaft moving(look under the hood)


if not then the transmission I/O shaft is broken


it's started by the transmission via HIGH speed 1500rpm start
and not a normal starter.. no normal 12v+ starter (they should have had redundancy though)

it's the one with the large pulley on it that would have connected to a mechanical A/C if was a reg one


if it's moving then you have a issue with the ignition system...



did you clean the engine or something before this happen?

did you do anything to the car before it happened?


this has a lot of tech info for it , you seem to be very technical
this will show you have to probe the correct wire to see if it has signal output when trying to start it..

read the
Output Speed Sensor information

The error code you should be getting is P16F3,P2160,P077B,P0722... or similar


if possible,(and safe i.e flat land ) as soon as you start it put it in Drive so you can get your "check engine light"
