I have a 2001 s10 Blazer 4wd Automatic 4.3L. It will crank over but won't start. Fuel pressure is good and ignition (key) start sequence appears to be fine. Security light goes out when attempting to start also. It is getting no spark. We have retrieved mil code of P1351A Ignition Coil High Pulse Ground Cylinder 1. We have replaced coil, ignition module, crank sensor, inspected cap and rotor and most wiring as well. Any other ideas on why no spark?
