I've got a 93 Camaro Z28 that is giving me DTC code 46 but I've already bypassed the VAT system with the resistor under the dash and the car will crank but no start. The Injectors are firing with the noid light But I've got no spark with a code 46 I believe that's a fuel shutdown so I shouldn't have blinking noid lights, any help would be helpful.

 

check for power at the pink wire to the coil.

Try starting with starter fluid, if it fires the problem is fuel related if not spark.
