I have 1991 ford ranger with 3.0 engine. When I try to start it has no spark unless I disconnect and reconnect battery. Any ideas?

Maybe you need to tighten the connections. But with a truck that's almost 29 years old, there are MANY problems you might have. It would be best to replace it.

Clean and tighten the battery terminals.
