Wade: You have two oil pressure sensing switches. The low pressure switch (4.4) must open between 2.2 and 6.5 psi. It is located between cylinder 3 and 4 The other switch (13.1) must close between 10.9 and 14.8 psi. It is in the vicinity of the oil pump. The flashing LED is associated with the 4.4 sensor. The flashing LED and the buzzer occur with RPM>2000 and no switch closure from the 13.1 sensor. A loose connector in the engine compartment gave me the LED/Buzzer symptom . Hope this helps Ken Lewis kdlewis@juno.com __________________ /---------/| || || / / | || || /--------------------|+========+| |[|]____[|]| _.| |==========| | | _ | _ | | ====== | / \| / \ | [__________]|_|)||_________|)|__[] \_\_/ \_\_/ \_\_/ \_\_/ 86Doublecab pickup 85GL 60 356(almost finished) 61 AH Sprite (for sale)
