On the diagnostic connector under the driver side dash, jump T1 and E1 pins and turn the ignition switch on with engine off. The check engine light will flash you the codes if there are any stored. OBD1 is not very reliable. If the light just keeps flashing then there is no codes. If the light blinks twice, quick pause then blinks six times then that will be code 26 and then it will pause and blink some other codes if any until it repeats itself.
As for the coil not sparking, you could have a bad distributor? Here is a diagnostic flow chart from the Toyota manual. Follow that chart and that should help you figure out what is going on.
Good luck to you and let us know what you find.
