I have replaced the camshaft sensors and crankshaft sensors after light engine on and codes appeared p0016, p001. Now the car crank but not start I have no idea about the issue.

Have you checked for codes again after clearing these? If it was starting before and all you did was change these sensors, then we need to double check everything.

We need to make sure the sensors are correct for this engine and that they didn't give you the wrong ones. Then we need to make sure the connectors are fully seated. Checking codes will help with this as you should have open sensor codes if they are not plugged in.

Clearly you are aware how to pull codes but here is a guide that will help others if they are reading this:

So let's pull codes and double check the part numbers they gave you. Lastly when you crank the engine does the RPM gauge move at all?

Thank you so much for your reply.
Well, I went to the car now and it started but it shows “engine power reduced” and I struggle with pressing gas.
I will go and buy a device to check for codes, the last time AutoZone checked it for me.

Sounds great. Don't feel like you have to buy a tool. Having a parts store checking them will work as well. Thanks for the update.

Okay. That is not terrible news. It at least explains the no start issue. Take a look at these attachments and tell me if these other codes are the ones listed on this testing. The P00c8 is an open circuit DTC so maybe we should go back through the connectors that you took apart and make sure none are loose. That would explain why this started after the repair you made. It will also explain why you have a lot of other codes as I suspect they are all open circuit codes as well.
