E car turns over but no spark and I have changed crank sencer sparkplugs and wires I chane coil packs I get no spark
In the circuit between the crank position sensor and the coil packs, is the ignition control module. It not only amplifies the crank position signal, but also does things like set the ignition advance curve as rpm goes up. It is expensive, but could be bad. First check to see it it is getting power, and it is not a fuse or a relay before trying that unit.
