Customer Question

I HAVE A 1989 BUICK ELECTRA WITH A 3.8 ENGINE. THE CAR WAS STALLING ON ME FOR ABOUT A MONTH. THE OTHER DAY WHEN I WAS DRIVING, I LOST POWER AND WAS RUNNING LOUSY. I MANAGED TO MAKE IT HOME AND WHEN I OPENED HOOD TO SEE WHAT THE PROBLEM WAS, IT WOULD STILL IDLE BUT WOULD BACKFIRE WHEN YOU GAVE IT THROTTLE. I SHUT IT OFF AND NOW IT WON'T START AND IT POPS OR BACKFIRES THROUGH THE INTAKE. I FORGOT TO MENTION THAT WHEN I WAS DRIVING, I MIGHT HAVE SMELLED SOMETHING BURNING, LIKE ELECTRICAL. MY CAR RAN LIKE THIS WHEN THE IGNITION MODULE WENT OUT SO I REPLACED AGAIN TODAY THINKING THAT WAS THE PROBLEM. I REPLACED THE COIL PACK LAST TIME WHEN I REPLACED THE IGNITION MODULE BUT I DIDNT WHEN I PEPLACED IGNITION MODULE TODAY. THE TILT STEERING COLUMN IS REALLY LOOSE SO I WAS WONDERING IF THIS MADE MY IGNITION SWITCH GO BAD OR WHAT ELSE COULD BE THE PROBLEM? IT SEEMS LIKE IM GETTING PLENTY OF FUEL PRESSURE

Special Tool; Assembly





*** UPDATED BY TSB #91-6E-5 DATE: 11/90

The harmonic balancer on these engines is now press fit on to the crankshaft and requires the use of tool J-38197 for removal. The torque specification to be used during installation has also been revised from what was originally published. The procedure to be used when replacing the crank sensor is as follows:

REMOVAL:

1. Disconnect the serpentine belt from the crankshaft pulley.

2. Raise the vehicle on the hoist.

3. Remove the right front tire and wheel assembly.

4. Remove the right inner fender access cover.

5. Using a 28 mm socket, remove the crankshaft harmonic balancer retaining bolt.

6. Remove the crankshaft harmonic balancer using tool J-38197.

7. Remove the foreign object deflector (DO NOT use a pry bar).

8. Disconnect the sensor electrical connector.

9. Remove the sensor and pedestal from the block face.

10. Remove the sensor from the pedestal.

INSTALLATION:

1. Loosely install the crankshaft sensor on the pedestal.

2. Position the sensor with the pedestal attached on tool J-37089.

3. Position the tool on the crankshaft.

4. Install the bolts to hold the pedestal to the block face, torque to 30 Nm (22 lb ft).

5. Torque the pedestal pinch bolt to 4 Nm (35 lb in).

6. Remove tool J-37089.

7. Install the foreign object deflector.

8. Place tool J-37089 on the harmonic balancer and rotate the tool. If any vane of the harmonic balancer touches the tool, replace the balancer assembly.

9. Install the balancer on the crankshaft.

10. Apply thread sealer GM #(NNN) NNN-NNNNor equivalent to threads of the crankshaft balancer bolt. Using J-36660 Torque Angle Meter, torque the bolt to 140 Nm + 56 degrees (104 lb ft + 56 degrees).

11. Install the inner fender shield.

12. Install the tire and wheel assembly. Torque lug nuts to 140 Nm (104 lb ft).

13. Lower the vehicle.

14. Install the serpentine belt.

tims auto repair :

yes..the crank sensor is a very good suspect here...

tims auto repair :
Customer :

the tilt steering column is real loose and when I would make a sharp right hand turn, it would stall before this happened

tims auto repair :

i see

tims auto repair :

i wouldnt think this is the problem sense the ignition switch is on the lower of the column

tims auto repair :

though we can not rule it out..

tims auto repair :

but,,sense it acts as if it is out of time,,,i lean torward the crank sensor,,or ignition module

tims auto repair :

these crank snsors would go bad from time to time

tims auto repair :

the engine would die as if the key was turned off

tims auto repair :

then,,after it sat a while..would restart as if nothing was wrong.

tims auto repair :

nad,,not give a code

Customer :

I was going to try a new ignition switch first before crank sensor, since I don't have special tool to replace sensor or puller to take off balancer---- as much as I dislike taking to mechanic, I might have to id rather fix myself

tims auto repair :

yes

tims auto repair :

i understand that

Customer :

maybe coil pack?

tims auto repair :

the coil pack is also posible

tims auto repair :

i always replace it with the ignition module

tims auto repair :

it is posible for the coil to go bad and send high voltage to the module,,burning it out

Customer :

ok, will try new coil pack also but ignition module was new out of box that I installed today.

tims auto repair :

yes

tims auto repair :

but

tims auto repair :

if the coil pack was bad at first,,it could have burnt up the new module as soon as you tried to start

tims auto repair :

this is why you need to have the module tested

tims auto repair :
Customer :

I also need to know how to fix loose tilt steering column

tims auto repair :

you need to remove the steering wheel

tims auto repair :

and tighten the bearing in the tilt

tims auto repair :

i will see if i have something on this

tims auto repair :

one second

Customer :

when I figure out problem, I will get you paid

tims auto repair :

i dont have allot of pictures on this old of model

tims auto repair :

but..remove the steering wheel then the spring,,then you can tighten it

tims auto repair :
Customer :
