Start motor for a vehicle to go to blazes! (4,6)
I believe the answer is:
fire engine
'go to blazes' is the definition.
I can't judge whether this definition defines the answer.
'start motor for a vehicle' is the wordplay.
'start motor' becomes 'fire' (I can't justify this - if you can you should give a lot more credence to this answer).
'for' says to put letters next to each other.
'a vehicle' becomes 'engine' (engine is a kind of vehicle).
'fire'+'engine'='FIRE-ENGINE'
'to' is the link.
Can you help me to learn more?
(Other definitions for fire engine that I've seen before include "Red vehicle" , "emergency aid" , "Operate ignition" , "Vehicle carrying a ladder and hoses" , "vehicle needed in emergency" .)
