1999 Other Plymouth Models Automatic

I have a '99 Plymouth Neon DOHC 2.0L & on saturday it sounded like I hit something as I was driving to my friends house the car road fine and when I was leaving her house I noticed alot of water on the ground again on the way home the car ran fine I stopped at the store and when I started the car back up it sounded like I needed an oil change then on the way home it just started coasting til I turned it off now it will not start. I didn't overheat but as you put water in the radiator it runs right out. I was told it was a bad water pump and that I should replace the timing belt as well. What are the possiblities of me also having a blown head gasket?

What are the possiblities of me also having a blown head gasket?

Have it block and pressure tested-do the block first to pinpoint a combustion leaking into the cooling system or a gas analyzer to sniff for hydrocarbons at the radiator fill neck.

Pressure test: do not do a pressure test if there's leakage at the headgasket this might cause coolant into the cylinders and lock it up or bend a connecting rod if cranked thereafter. The headgasket should be repaired before doing the pressure test.

If the block and pressure test passes check the following:, Pressure test the Rad. Cap, Clogged radiator, air lock in the cooling system, Fan clutch, Radiator electrical fan, collaspe hoses, water pump.
