Does not start?

Hi,

Most commonly, a loss of spark is caused by failure of the crankshaft position sensor. By chance, do you have a live data scan tool? If you do, check to see if there is an RPM signal when cranking. If you don't, if the vehicle has a tachometer, see if it moves at all when cranking. If it doesn't, suspect the sensor.

I don't know if this happened all at once but take a look through this link and let me know if anything seems to mirror what you have experienced:

If you find this is the issue, here is a link that explains how in general to replace one:

I attached a pic below showing the sensor location.

Let me know if this helps or if you have other questions.

Take care,

Joe

See pic below.

When i changed the sensor, it sparks but he doesn't start. Later I checked it back he doesn't spark again if the crankshaft bank1 sensor1 and crankshaft bank1 sensory are not the same, can it cause it?

This is the engine that bring.

That is the two sensor I change crankshaft sensor the down one it spark in the first place later it doesn't spark anymore please I also use MaxiScan OBD2 it also detect the two sensor and I have change it but still the same thing.

Hi,


With the scan tool connected, do you get an RPM signal? Since you got spark and then lost it again after replacing the sensor, what condition is the wiring and connector to the sensor?

Joe

The wiring is okay, because if the motor starts now it can work for good 5 to 6 months without doing anything.

Hi,

I understand. What you need to do is check when it won't start for you. Hopefully, it will never happen again. However, if your luck is like mine, it will.

Keep in mind, moving the connector and wiring may be allowing a good enough connection for it to run. So, if it happens again, check for an RPM signal first. If there is none, disconnect the sensor and reconnect it to see if you get one.

Let me know.

Take care,

Joe
