Hello I have a 1985 blazer k5 I've replaced everything in the distributor the pick up ,the control module, condenser,check the wiring for continuity. I've got 12 volts going to 12.75 volts to the distributor I have great ground I got my secondary grounds she cranks but won't start she gets plenty of gas I don't know can anyone help?

 

how are your ignition wires.you didn,t say if had changed them,if not it could be a bad coil wire.i have this happen where a customer did his own sort of tune,replaced plugs,cap,rotor but not the ignition wires.turns out it was a bad coil wire.so i changed all the ignition wires because they were the original wires.vehicle ran great after wires were changed.hope this helps.
