Engine shuts off intermittently while driving

Hi,

The neutral safety switch will prevent it from cranking if it isn't in park or neutral, but it won't cause the stall.

To me, it sounds ignition related. If you allow the engine to idle, does it stay running? If not, do me a favor. Check to see if the coil power supply is losing power when this happens. I have no schematics to look at because of the ignition change, but at the distributor, there should be a power supply for the ignition coil that is hot with the key on and in the start position. If you find there is a power loss, I would next check the ignition switch for wiring issues.

Let me know what you find.

Take care,

Joe

Ed,

I suspect it is ignition-related, but the idea that it idles makes it a bit more difficult. If it was fuel-related, it would take cranking for some time to refill the carb bowl and not start immediately.

Do me a favor. When it is running (idle) wiggle the wiring harness to the distributor. If there is no change, do the same with the wiring to the switch.

Let me know if anything changes.

Ed,

I am going to ask another tech that is better than me on the older vehicles. Let's see what he says. Hang in there.

Also, let me know if you checked the ignition control module.

Hi,

I wanted to let you know I got a reply from the site owner. I asked about your problem. Here is his reply to me:

"I have seen the fuel lines at the tank do this, even if they don't leak, they can allow air to enter the suction side of the pump which will stop the pump operation"

It may be worth checking to see if they are in good condition.

Let me know.

Joe

Hi,

You are very welcome. I hope everything is okay at home. Take your time and let me know when you get a chance.

Take care,

Joe
