Nissan Altima

I have a 1994 nissan altima with 210,000 miles It turns over and gallops like it wants to start but it wont I checked the light on the computer and it gives me a code that says its the knock sensor but would the knock sensor keep the car from running and is there any way of getting another code after it says its the knock sensor cause someone said it could be the tamp sensor but the only code I got was the knock sensor
