Hold on a sec.A lot of trouble shooting needs to be done before you start replacing expensive parts.
First, if you have no spark, check the connectors on the distrubuter for loosness or corrosion.
Check power supply to the ignition coil. Turn on the ignition switch, and check if there is battery voltage at the ignition coil (+) terminal. If not, suspect ignition switch. If good voltage, check the resistance of the ignition coil. Resistance cold should be Primary 0.4-0.5 ohms and secondary 10.2-14.3 ohms. If good check resistance of the signal generator pickup coil. Resistance cold should be G+ and G- 185-265 ohms NE+ and NE- 370-530 ohms.
If this is good check for air gap of the distributor. Should be 0.2-0.4mm (0.008-0.016 in).
If that is good, check IGT signal from ECU.
Judging by the symptoms, it does sound like a bad coil, but its always best to trouble shoot.
