1998 Chevrolet K3500 454 vortec has no spark
I replaced the distributor, cap and rotor, plugs and wires, ign module and coil, After I replaced them the plug for the oil pressure sensor shorted out on me and had to replace that and the sensor. The compression is good on all eight cylinders, fuel pump kicks on and builds up to the recommended psi. I still have no spark which I have some what narrowed down to the switching signal is not being sent, is there something I am possibly missing for a no spark?
I forgot to mention also that there is no codes when hooked to a reader.
