Re: 1992 Seirra Will turn over but not start

Looking at my factory manuals for a 90, the Ignition Module is likely the cause of your problem. Although, the ECM can be at fault.

Some auto parts stores can test the ignition module.

If you want to test it your self, remove the 4 wire connector at the distributor. Ignition on, noid light on one of the injectors, take a test light and hook one end to +12 and the other end to the purple/white wire in the 4 wire connector. Every time you remove the test light from the purple/white wire, the noid light should flash. If it flashes, ignition module is bad.

If it does not flash, it could be wiring or ECM. My money is on the ignition module.
