    Maybe your glow plug relay is bad. It looks like a starter solenoid.

    might have water in the fuel or a cracked line. does it smoke.
    most likely your due for new injectors an 89 with high mileage would be due for injectors. I’d check the obvious then do the injectors.

    Engine Size & Mileage? How Long Does it Run before it Dies? Dies in or Out of Gear? Standard or Automatic? Starts Easy or Hard? Glow Plug System Comes On & Goes Off before Start? When Was the Last Time the Fuel System was Serviced? What Lights do you get on the Dash when it Dies?
