The speed sensor on a 90 lumina 3.1 should be on the drivers side top of the tranny, below the steering rod. Sould be a screw in sensor with wires attached.
There are a few reasons. crankshaft position sensor, faulty fuel pump, fuel pump regulator, throttle position sensor, oxygen sensor. Need to have it diagnosed.
In the glove box
The gas tank on a 1991 Chevrolet Lumina holds 17.1 gallons, and it takes regular unleaded fuel. The car comes with a 3-speed automatic transmission.
hire a mechanic
Should be by the alternator in the back
it is located next to the ecm behind glove box
you dont only a certified repair shop can handle R12
If it is an automatic transmission it is most often the torque converter that will cause the jerking motion of the car.. another way to tell is the car will start to die when you come to a stop.AnswerI had the same problem in my 93 lumina euro... it's most likely the fuel pump. AnswerMy 92 Chevy lumina did the exact same thing, it turned out to be my crank sensor, and crack sensor wiring.
how to add coolant to 1991 lumina?
Remove the negative battery cable then the cables off of the starter then the bolts holding it on and work it out.new answerOn the 3.1 engine, you will definitely have to remove the oil filter and possibly the crank position sensor.
no such thing
