Is the security light flashing?

10

Where is that

85,565

Flashing on the dash, a red light that says security.

10

No nothing.

Well thats good at least. Sounds like the Ignition Control Module is bad, located in the distributor. It can be taken out and tested at Auto Zone, or other parts stores. There is an ignition relay, but doubt that would be the problem.

10

I got the ICM test and it's good. So the distributor?

No not really, but you check the rotor to try and spin it. It should not spin, and if it does, then the pin sheared on the distributor shaft gear.

10

It spins

85,565

The rotor spins without the motor running or you turning it over? It spins by hand?

10

I take the cap of and turn it over and it moves

10

How do I tell if the distributor is bad

85,565

The only way the distributor in that one would be bad is if the shaft bushings were worn out. There would be play in the shaft that the rotor attaches too. So, have the cap off, put your hand on the rotor and see if you can move it. It will move a little bit but what you are feeling for is if that shaft is locked in place.

10

Does it need to be pointing toward #1

85,565

No, all your checking is if that distributor gear pin is sheared or not. At this point it does not matter where the rotor is pointing at.

10

We'll it just moves a little bit.

10

Man this has me scratching my head I can't figure it out

85,565

Ok then put it back together, the gear is ok. Check the Ignition Control Module at a parts store, since there a little spendy. Also when re-installing the ICM make sure and put dielectric grease on the matting surface of the ICM (bottom side). This protects the module from heat, and makes it last longer.

10

I had that checked and it good.

10

Could it be with the ignition?

85,565

So you say "not getting fire to the coil" I took that as you are not getting 12V at the coil. Did you pull the coil wire off and check for spark? There is a fuse for the ECM you may want to check also. When was the ICM checked? You had said nothing about the Ignition Control Module.. I'll be back in a 1/2 hr.

85,565

No not the ignition switch because it is turning over.

85,565

I am back.

10

Yes I pulled the coil wire off and no spark. I checked the fuses and they are good.

10

I ran a scanner and it said catalyst monitor, oxygen sensor, evaportive monitior, mass air sensor.

85,565

The only thing holding the spark up is the Ignition Control Module, But now you say you had it tested. Other than that it would be in the security system being activated, but again, you said the security light is not flashing. Or the coil is not getting 12V. Do you have a test light? I guess the only thing to verify would be to see if there is 12V at the coil. You pull the plugin and check the terminals to see if there is 12V on one of them. One other possibility is that if the coil is not grounded good.

85,565

What you found with the scanner has nothing to do with spark.

10

I don't have a volt meter but I used a test light and it lights up when I test it

10

How do I make sure the coil has a good ground?

85,565

Clean up the contact points on the metal that run around the outside of the coil where it mounts to the bracket, and clean the contact point on the bracket to where it bolts to the motor. Is there a green wire bolted to the outer metal casing of the coil? That would need to be cleaned as well.

10

Thanks for the help by the way your the only one that has helped me. I can't even get help to do this so sorry if I ask slot of questions.

10

No there is no green wire on the side of it only the connector and the coil wire.

85,565

No problem man, you have to just be missing something we have gone over, we have gone over everything that makes it run. E-mail me if you want if you have questions about anything.

85,565

Just make sure the mounting surfaces are good and clean and tight.
