Question about 1994 Toyota Camry
1994 toyota camery 2.2 eng. no spark at plugs. I have already replaced ignition module, still no spark. Everything else seems to be ok, eng. turns over good timing belt is intact ect... The car just shut off one day. I have also replaced cap & rotor also spark plugs. what would be the next guess? Distributor & Coil seem to be one unit.
I had the same problem recently but replacing the ignition Coil under the distributor (inside) solved the problem. Also replaced the distributor Cap and rotor at the same time.

Have a look at:
Test the ignition system output, ignition systems can vary in configuration but operate on the same principal. Ignition systems can consist of a coil, pick up coil, crank angle sensor, cam angle sensor, spark plugs, spark plug wires, distributor cap, ignition rotor and a distributor and any variations of these components. An ignition coil is a voltage stepper coil that transforms a low voltage (12 volts) signal into tens of thousands of volts needed to jump the gap of the spark plug. This coil is activated by an ignition module triggered by using the camshaft/crankshaft angle sensor, timing is adjusted by the ECM (computer). This primary electrical signal is generated by the ECM which calculates spark timing by using a variety of sensors including coolant temperature, mass air flow, and oxygen sensors. To perform a basic ignition output test you must have a test light and follow this ignition system output test video.
If the ignition system test is weak or non-existent test the car fuses, both under hood power distribution center and the fuse panel under dash. This test is performed with a test light tool. The test light should illuminate on both sides of the fuse, if not the fuse has failed and needs to be replaced. If the fuses are ok a manufacturer specific repair procedure is required and an online auto repair manual is needed to continue. If the ignition system tests ok proceed to the next step.
