Put a little gas in the carburetor and it hits but won't run. Runs just second and shuts off.

Hi Sue,

You have already identified the problem. It is certainly fuel related. If I recall, in 1986, these vehicles had a mechanical fuel pump. If you follow the fuel line from the carb, it will lead you to the pump. If it's fuel-injected, it's a different story.

Here is the issue. In 1986, it appears the vehicle could have come with either an electrical or mechanical fuel pump. Does the vehicle truly have a carburetor or is it fuel injected?

Let me know.

Joe
