Buzzing sound from the engine bay!? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I have a 93 240sx that won't start. Cranks over but seems like no fuel or spark is getting to it.

I've researched for weeks trying to figure out what it is but still nothing... It's a stock KA on coilovers. Rubbed through a little bit of the harness and found two wires that were exposed so I taped them up and tucked it more.

The buzzing sound is coming from the intake manifold side/ firewall, I take the ign switch fuse out and it stops. I step on the gas pedal and it stops. Already replaced the battery with a brand new one today and got it to run but the buzzing came back and the car won't start again . My fuses are all good too...

My terminals are good and clean, fuses are good. What else should I be looking for? I checked te main grounds to the motor but what else grounds should I look for?

Any help is appreciated!
