1992 Geo Metro will not start on its own

Are you saying it cranks over and will not start or just won't crank at all/nothing

Cranks over and will not start:

disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, cap and rotor /distributor pick-up coil, ignition control module, ECM, Ignitor cam and crank sensors- Note: If it doesn't apply disregard it

No crank at all/nothing:

Could be the battery and connections, starter, starter relay, clutch switch and ignition switch
