Re: 99 blazer 4.3L no spark
Fuel pressure is way low.
Jumper the fuel pump or bump the ign a couple of times to prime up fuel pump to full pressure.
But that does not explain the no spark.
If you have crank sensor signal or rpm signal and the coil is good check ign module.

Do you have a scanner to see if the pcm/vcm is getting a rpm signal or crank sensor signal?
Any remote start or add on anti theft?
