You should have 2 keys for the car. Try the other key !
The keys are special and have a code on them. Any other key that is not with the code will not work.

 

i don't have an other key.i changed ecu and gem module once car cranked but after again same problem. will you tell me which module is controlling key code?can i change that device?

 

The PCM has to be reprogrammed to accept the old key code. It should be done by a dealership.
On your vehicle the onboard computer (PCM) controls the PATS . Not too many places have the equip to do this. You might have some luck with a locksmith . Some of them can do this and possibly for a lot less $$$.

 

i replaced a used pcm and now crank good but wouldn't start.what to do?

 

You have two choices.
Either get the replacement ECU/pcm programmed for your only key or get the key and key tumbler from the vehicle where the replacement ecm came from. The PATS system is controlled by the PCM and will prevent the starter from working & the fuel injectors from injecting.
