I have a Toyota Noah checked all electrical and sensors but vehicle has no spark. Where should I start from?

Its only giving me P1755 and P1760. These codes are for transmission. Can these codes make a vehicle fail to start?

It is a Toyota Noah (Voxy type) with a 1AZ engine. It also has the injector drive ECU.

Hello,

It sounds like the crankshaft angle sensor has gone bad which is common for these cars. Here is a guide to shot you what you are in for when changing the sensor.

and a guide (below) so you can see what it is like on your car.

The transmission codes will not make the engine not start.

Please let us know what happens.

Cheers, Ken

Expect to find a lot of other blown fuses. There are a lot of complicated computers on cars today that will be damaged from reverse polarity. They have diodes built in to create a short on the line to force fuses to blow before that damage to the computers takes place. Most of the time those diodes save the computers.
