I got a 1995 camaro 3.4l v6 i just bought it for my son it is his first car. It was running fine for about a week. Then he got in it one day tryed to start it and it won't start up, all it does is crank. We have changed the throttle body sensors, the harmonic balancer the crank shaft positioking sensor, the ignition control module, we also by passed the vats, it seems like the car is not getting spark for some reason. I need advice from people who nows what's up with this.

 

I forgot to mention that i noticed that the fuse under the hood marked ignition keeps blowing out every time i crank the car

 

We also have changed the fuel pump

 

Is your check engine light on? Have you scanned for codes?

 

get it scanned for codes (its obd1 even though the plug is obdII autozone cant scan it)

 

there may be some variation this is from the 93 book.

 

Never doubt that the spark plug wires/wire to the coil are the issue. My 94 z28 went from firing up incredibly fast to one day not starting at all. We had the waterpump off intending to change the optispark when the coil wire boot fell off and the wire inside was shot..got a new wire and it fired right up.

 

You need to find out why the IGN fuse is blowing, otherwise you will never get spark.

 

Till I got to this response, I thought I was the only one who caught on.
Does this mean the guy was still trying to start the engine, and was throwing parts at it, all while knowing the ignition fuse is blown? That's how it reads to me.

 

I noticed it after we changed the harmonic balancer and the crank shaft position sensor and the fuel pump.
