If the engine is not getting spark from distributor then vehicle will not start.
The spark gets power to spark from coli packs.In this case test the coils first.

I recommend you test the coil as indicated below. if the coil tests good, test the pickup coil. One or the other is bad.

See Figure 1

See Figure 1
- Tag and disconnect the distributor lead and wiring from the coil.
- Connect an ohmmeter as shown in Step 1 of the accompanying illustration. Place the ohmmeter on the high scale. The reading should be infinite.
Fig. Fig. 1: Fuel injected engine ignition coil test
- Connect an ohmmeter as shown in Step 2 of the same illustration. Place the ohmmeter on the low scale. The reading should be very low or zero. If not replace the coil.
- Connect an ohmmeter as shown in Step 3 of the same illustration. Place the ohmmeter on the high scale. The meter should not read infinite. If it does replace the coil.
- Connect the distributor lead and wiring.
PICK-UP COIL
- To test the pick-up coil, first disconnect the white and green module leads. Set the ohmmeter on the high scale and connect it between a ground and either the white or green lead. Any resistance measurement less than infinity requires replacement of the pick-up coil.
Fig. Fig. 4: Testing the pick-up coil-separate coil
- Pick-up coil continuity is tested by connecting the ohmmeter (on low range) between the white and green leads. Normal resistance is between 500 and 1500 ohms. Move the vacuum advance arm while performing this test. This will detect any break in coil continuity. Such a condition can cause intermittent misfiring. Replace the pick-up coil if the reading is outside the specified limits.
- If no defects have been found at this time, and you still have a problem, then the module will have to be checked. If you do not have access to a module tester, the only possible alternative is a substitution test. If the module fails the substitution test, replace it.
REMOVAL & INSTALLATIONSee Figure 1
- Remove the distributor cap and rotor as previously described.
- Disconnect the harness connector and pickup coil spade connectors from the module. Be careful not to damage the wires when removing the connector.
Fig. Fig. 1: Be sure to coat the mating surfaces with silicone lubricant
- Remove the two screws and module from the distributor housing.
- Coat the bottom of the new module with dielectric silicone lubricant. This is usually supplied with the new module. Reverse the above procedure to install.
