What is your question?

I have 95 Geo Prizm 1.6. It has high mileage. It was running good until this morning when i stopped to pick up a rock on the road. When i press the gas it stalled. It crack but won't turn run. I checked the fuel pump and fuel filter and they work good. Getting gas pass the filter. What do you think it is? Injectors or timing belt. Thank you, Thomas
