I have toyota nadia 1azfse car that cant start but if i put some petro in the manfold it start then dies

You haven't supplied much information.

The common rail system, while technically correct when describing a typical petrol engine is usually used to describe the more modern type of diesel engine.

It isn't a good idea to put petrol down the inlet manifold of a diesel engine.
This test when applied to a petrol engine proves the ignition system is in working order and the timings and the compressions are reasonably fit for purpose. The test would be better performed by an ether spray.

It seems the fuel in your car is not finding its way to the cylinders.
Possible reasons are the fuel pump fuse, relay, wiring or the pump itself. A blocked filter or fuel line is possible.

An electrical or electronic fault could be preventing injection even if sufficient fuel is available at sufficient pressure.
Certainly a systematic process should be gone through in order to discover the cause of your problem.

My toyota sienna jerks a lot. the first place said it was water in my gas and then someone said it was transmission. it does not seem to have any issues shifting but it seems to be missing alot when you...

I think I would be running the fault codes first to find exactly what is the problem. Missing is from fuel pressure and injectors or HT leads and coils and this will show up in the fault codes.. If you got water in the fuel then may be the filter is blocked so check that out.. If injectors show up it may be low fuel pressure in the manifold so have a pressure done there to check fuel pump/ pressure regulator and filter.

Toyota 5s fe engine stalling when hot no fault code

check for a bad coil. it may be shutting down engine when the thermostat opens. if bad it will not produce enough spark under warm or hot conditions. if this did not do it! check the fuel pump it may be getting hot and shutting off the engine. change the fuel pump relay with another of the same size. and see if thats your problem.

Toyota Nadia Stops suddenly

Check the fuel pressure when it stops ,could be a faulty fuel pump or even more so a faulty connection plug on the top of the fuel pump gauge sender unit
