Start with spark.Then to fuel.How many kms has it done.Do you service regular.Have you replaced fuel filter.Spark plugs.Leads.Its a big question your asking without much detail.How longs a piece of string.Im a qualified motor mechanic many years experience diagnosing for other younger less exp mechanics.

Go over the basics- check air filter and spark plugs (make sure the gap is still within specs).
Trade it for a Honda CRV.
