1989 Buick Park Avenue ? Didn't have ParK Ave. that year . Buick Park Avenue
It became an Electra trim level in 1978 and its own model starting in 1991 after the Electra was discontinued. Two generations of the Park Avenue were manufactured in the United States until 2005, while in 2007 the nameplate was revived on a large Buick sedan built by Shanghai GM for the Chinese market based on the Holden Caprice from the WM/WN range. The nameplate is derived from the affluent

Gasoline Engines The starters on some engines require the addition of shims to provide proper clearance between the starter pinion gear and the flywheel. These shims are available in 0.015 in. (0.4mm) sizes from Buick, Oldsmobile and Pontiac dealers. Flat washers can be used if shims are unavailable.

1. Important: disconnect the negative battery cable before proceeding.
2. Raise the vehicle to a convenient working height and safely support it with jackstands.
3. Remove the exhaust crossover pipe.
4. Disconnect all wiring from the starter solenoid. Replace each nut as the connector is removed, as thread sizes differ from connector to connector. Tag the wires for later connection.
5. Remove the flywheel housing cover and disconnect the oil cooler lines at the transmission, if necessary.
6. Starter removal on certain models may necessitate the removal of the frame support. This support runs from the corner of the frame to the front crossmember. To remove:
   1. Loosen the mounting bolt that attaches the support to the corner of the frame.
   2. Loosen and remove the mounting bolt that attaches the support to the front crossmember and then swing the support out of the way.
   3. Install the crossmember and mounting bolts. Torque the bolts to 80 ft. lbs. (109 Nm).
7. Remove the front bracket from the starter and the two mounting bolts. On engines with a starter solenoid heat shield, remove the front bracket upper bolt and detach the bracket from the starter.
8. Remove the front bracket bolt or nut. Lower the starter front end first, then remove the unit from the vehicle.
9. Installation is the reverse of removal. Make sure that any shims removed are replaced (please refer to the shimming procedure). Torque the two mounting bolts to 25-35 ft. lbs. (34-48 Nm). Connect the starter wires and install heat shields if removed.

The solenoid is located in the starter, I don't know any other relay for the starter

Standing in front of the car with hood up, just below front of exhaust manifold is the starter. Should be able to see it.

May be a starter fuse - but if blown, starter will not rotate engine. More likely a fuel starvation problem. Replace fuel filter in gas line - first choice. Next, have fuel pump pressure checked. If it has failed, you will get 4 -5 seconds of engine run before stopping.

You need to replace the control assembly.
