Knock sensor

[1992HD]

I recently replaced the air flow meter on my 1992 240sx thinking that, that was the problem. But my car still wont start and the ECU is saying now that its the knock sensor. Does anybody know if the knock sensor would prevent the car from starting? And if so, whats the easiest way to replace the it? Thankx

No it wont stop it from starting. You need to figure out what you dont have first. Fuel,spark or compression.

Thankx...I started looking at some more and now I think its the fuel pump because the line does not pressurise and the fuel just trickles out of the line. I appeciate your help!
