If you're not getting sparks on those two iginition coils, then the coils may have failed. Since you already have determined there are no sparks, verify further:
1. Engine at idle, disconnect the wiring connector on those coils one at a time. If engine speed (rpm) remains the same, that iginition coil is bad. Do the same test on the other coil. If you get the same results, then replace both ignition coils.
2. After you have disconnected the connector and engine speed drops and engine may even stall, that coil is good. If the test on the other coil is the same, save yourself money on new coils because The no spark is caused by something else.
