20 Most Recent 1989 Buick Park Avenue Questions & Answers


!.The car will jerk when you accelerate, especially if your fuel filter has been blocked due to accumulated waste in it. but you would lack power always.
cuz it's fuel injected very well might be a bad throttle position sensor. TPS for short.
one or the other is my belief. will take awhile for the tps to throw a hard code. so i'm betting on that. ck rockauto for price of the unit i don't think it'll break the bank.
Hope this helps.

Have you checked for voltage at all those locations you changed parts or checked?Have you checked for voltage back at the pump?Have you checked the ground for the fuel pump?Also,other than the priming cycle,fuel pump voltage runs through the oil pressure switch when the engine has oil pressure.
You could keep cranking the engine until you have oil pressure and the pump may just start on that circuit,

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.

It may be a battery in the remote that needs replaced, otherwise you will need to replace the remote it self. You may need to have it serviced by a qualified technician.
