Engine not starting

Here is a link on how to test the fuel injectors. If the test light lights up then replace the faulty injectors. If test light does not light up then check for a short or open circuit for the fuel injectors.

This sounds like a fuel pump or the crankshaft angle sensor has gone out. When you turn the key to the on position without cranking the engine over can you hear the fuel pump run in the tank for 5 seconds?

about six months it was house garage as ideal condition it was running condition now car not starting, hence renewed wiring harness. overhauled engine with new piston ring, though tried out cranking, but engine not starting. If put some octane through inlet line engine tends to start, but finally not starting the engine.

we have no information on this car, but try to reset security system that is normally the cause if it ran before. see link.

The check engine light comes on during checks. the computer box was tested on another vitz and it works

You need to scan the system for the set fault code, do this and post the code here.

The box will not allow us to get the code.

The car was still running when I stopped it. But it surprises me, when starting it after some hours, it then cranks but could not start. I checked the fuses, spark and fuel, but those are ok. Now I don't know how to deal with these problem. Please help

engine fails to start it just cranks. I checked the timing and it is on the marks. the fuel is there and the spark too.

Check that the theft deterrent system is not activated (if equipped).
Check fuel pump fuse and/or relay. Replace as necessary. If all is well, spray carburetor/throttle body cleaner into the throttle body and then try starting the vehicle. If it starts, suspect contaminated fuel or a faulty fuel pump.
