it was running fine a couple days ago then when i tried to start it to go to work it was cranking but wouldn't turn over what could it be???

i changed my spark plugs yesterday and someone said it might not be getting spark even if you changed them

i just need a few ideas of what it could be so i can get my baby running again

 

It could be a number of things. Bad distrubutor, bad fuel pump, incorrect timing, usually changing spark plugs won't make a car just magically start running. You need to check for spark with a spark tester, check fuel pressure, see if the injectors are firing, check the timing belt to make sure it didn't break.. If you don't have the tools to do all of it I would just recommend taking it to a shop and have them do it.
