98 blazer wont start after oil line blew

i have a 98 blazer i was driving it last night and the oil cooler line blew and the check guages light came on oil pressure dropped to zero and the truck lost power and shut off.. i rolled it into a parking lot and got the line fixed and filled back up with oil and now the truck will not start… i changed the battery out thinking it was that then changed the starter relay out as well the truck just makes one solid click noise
