spark problem

[Tyler Scalise]

i have a 1996 gmc k1500 5.7 vortec I have no spark i changed the distributor and rotor ignition coil plugs and wires still nothing any help????

Do you have power at the distributor?

 

Are there any ignition related relays or maxi fuses?

I had same issue i thought it was cap rotor dist related added new ign coil module plug wires etc no luck  ended up being relay to fuel pump...idk why or how just swapped it as a hail mary and truck fired up so try that if all else fails
