My car was skipping a little and so I put plugs in it, the wires were fine. Now it has no spark. I have checked the relays for auto shutdown relays are good. Do I need to replace the distributor or is their any thing I've forgotten to check?

Hi and thanks for using 2CarPros.

If you lost spark, confirm that you didn't disconnect anything by accident. If everything is attached, the first thing I suspect is a faulty crankshaft position sensor.

If you have a live data scanner, connect it and crank the engine. See if there is an RPM signal. If there isn't check to make sure the crankshaft position sensor wasn't disconnected. It is located on the transmission bell housing. See picture 1

Here are a couple links you may find helpful:

IF you determine the sensor is bad, here are the directions specific to your vehicle for the sensor replacement.

Removal
To remove follow the steps listed in the image.

See Picture 2

Installation
To install reverse the steps listed in the image.

If there is a crank signal (RPM) and still no spark, here is a test to check the coil which is integral with the distributor.

See Picture 3

1. Measurement of the primary coil resistance
Measure the resistance between connector terminals 11 and 12 of the distributor.
Standard value: 0.6 - 0.8 ohm
2. Measurement of the secondary coil resistance Measure the resistance between the high-voltage terminal and connector terminal 11.
Standard value: 12 - 18 k ohm

Let me know if this helps or if you have other questions.

Take care,
Joe
