crsctl start crs does not work in 10gR2

How to start crs in oracle 10g , its simple first we need to check if its really exists or not :

1-./crsctl start crs

Attempting to start CRS stack
The CRS stack will be started shortly

2- ./crsctl check crs

Failure 1 contacting CSS daemon
Cannot communicate with CRS
Cannot communicate with EVM

3- ./srvctl status nodeapps -n 

PRKH-1010 : Unable to communicate with CRS services.
[Communications Error(Native: prsr_initCLSS:[3])]


4- ./srvctl start nodeapps -n 

PRKH-1010 : Unable to communicate with CRS services.
[Communications Error(Native: prsr_initCLSS:[3])]

5- ./srvctl status nodeapps -n

     --------------------------------------------------------------

./crsctl start resources
