Check all your fuses with a test light again. There is a separate fuse for the "keep alive" memory for the radio.

Also make sure that your battery connections are clean and tight. If you have a poor connection, the starter could drop the voltage enough to reset everything during cranking.





Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

Wild maybe but had the problem once like and was the rubber block with all the wiring thru firewall with a zillion connections there covered in white grease. When the load of starting it lost contact enough for other items inside. That was an '89 GM van by chance and just a slight twist on the male spades of the connections made all contacts work properly again.

As said a wild maybe??
