And we need more detail. What happens when you turn the key,
Nothing at all?
Dash lights come on but starter does not turn - do the dash lights dim when key is at starter position, can you hear clicking?
Starter spins but is it engaging, is the auxiliary belt turning, is the cam belt/chain turning?
Is the engine spinning faster/slower than normal?
Was it running ok prior to this?
Is the EML flashing?
Impossible to answer this question without full information.
