92 sunbird cold start
 

i just bought a 92 sunbird le with the 2.0 and it does not like to start when the engine is cold unless you keep cranking and once it does start it starts fine until it has sat for 4 or more hours then does it again.
where should i start looking, could it be the plugs or? i haven't had a chance to pull them yet to have a look.
thanks
