Not sure on that truck but check the fusible links at the starter harness.

That 89 burb is a square body so it has a fusible link between the brake booster and the center of the firewall that should be checked. It is near the battery junction block by the booster.

For those of you that are wondering why you are not getting replies to your thread:

Did you give the model, year, engine, fuel system type, and transmission information?

If your vehicle has been altered from stock, let us know about that too.
