Question about 1994 Oldsmobile Eighty Eight

1 Answer

Car constantly shuts off and won't start sometimes

I recently change my module, spark plug coils, harmonic balancer and crank seal. My car still hesitates until it's warmed up. I have difficulty starting it in the morning and sounds like no gas is getting where it's supposed to go. Need help and answers

    my car will start up, then after a while it will bog down and stall; also, it seems like im getting no gas and the car has no power, however the motor idles and runs fine...( if i slam on the breaks it stalls too. )

    Run a fuel pump leakdown test, test the MAF sensor. Check for trouble codes

Try changing the crankshaft position sensor - I hear this is a common problem for the 88's, and the part is only about $30.

Cranks but no spark


could be a lot of things . crankshaft sensor, ignition module, coil module. you need more test, look crank sensor behind harmonic balancer remove crank sensor to see if it touch the metal.

Check for spark. My guess would be the ignition module going out, but could also be the crank sensor. The module sits under the coils. Check all coils for spark. If any coil doesn't spark, you can try replacing just that coil, but the problem may still be the module underneath. If you have a meter, run a resistance check on each coil from the terminals to ground. If the same coil that doesn't fire aslo has a different resistance, replace that coil.
If you have a meter, check the AC voltage on each of the crank sensor wires shown as compared to ground or battery positive. If the AC voltages are different on the three wires, suspect the sensor is bad, but also check the tone ring on the pulley (Fig 2 below) for any damage.
Please see my tip at http://www.fixya.com/cars/r5821173-doesnt_car_start_gasoline_engines for how to check for spark. These are genericinstructions.
The 3.3L engine is the only one with the C 3 I system. REMOVAL and INSTALLATION C3I Module See Figure 1
  1. Disconnect the negative battery cable.
  2. Unplug the 14-way connector at the ignition module.

Fig. Fig. 1: Distributorless C 3 I coils and module system - 3.3L engine
  1. Tag and disconnect the spark plug wires at the coil assembly.
  2. Remove the nuts and washers securing the C 3 I module assembly to the bracket.
  3. Remove the 6 bolts attaching the coil assemblies to the ignition module.

To install:
  1. Install the coil assemblies to the ignition module and install the 6 attaching bolts.
  2. Install the nuts and washers attaching the assembly to the bracket.
  3. Connect the spark plug wires.
  4. Engage the 14-way connector to the module.
  5. Connect the negative battery cable, then reset the clock, radio and any other accessories.

Ignition Coil(s)
  1. Disconnect the negative battery cable.
  2. Tag and disconnect the spark plug wires.
  3. Remove ignition coil attaching bolts, then the ignition coil from the module.

To install:
  1. Install the coil(s) and attaching bolts.
  2. Connect the spark plug wires.
  3. Connect the negative battery cable, then reset the clock, radio and any other accessories.

Dual Crankshaft Sensor
See Figures 2, 3 and 4
  1. Disconnect battery negative cable.
  2. Remove serpentine belt from crankshaft pulley.
  3. Raise and safely support the vehicle.
  4. Remove right front tire and wheel assembly, then the inner access cover.
  5. Remove crankshaft harmonic balancer retaining bolt and crankshaft harmonic balancer.

Fig. Fig. 2: Harmonic balancer with interrupter rings on C 3 I system
  1. Unplug the electrical connector from the sensor and remove the crankshaft sensor from the vehicle.

To install:
  1. Loosely install the crankshaft sensor on the pedestal.
jturcotte_1658.gif

Fig. Fig. 3: Dual crankshaft sensor - C 3 I system
  1. Position the sensor with the pedestal attached on special tool J-37089.
  2. Position the tool on the crankshaft.
  3. Install the bolts to hold the pedestal to the block face. Tighten to 14-28 ft. lbs. (20-40 Nm).
  4. Tighten the pedestal pinch bolt to 30-35 inch lbs. (3-4 Nm).
  5. Remove special tool J-37089.
  6. Place special tool J-37089 on the harmonic balancer and turn. If any vane of the harmonic balancer touches the tool, replace the balancer assembly.

A clearance of 0.025 inch is required on either side of the interrupter ring. Be certain to obtain the correct clearance. Failure to do so will damage the sensor. A misadjusted sensor of bent interrupter ring could cause rubbing of the sensor, resulting in potential driveability problems, such as rough idle, poor performance, or a no start condition.
  1. Install the balancer on the crankshaft and install the crankshaft balancer bolt. Tighten to 200-239 ft. lbs. (270-325 Nm).
  2. Install the inner fender shield.
  3. Install the tire and wheel assembly. Tighten to 100 ft. lbs. (140 Nm).
  4. Lower the vehicle.
  5. Install the serpentine belt.
  6. Connect the negative battery cable, then reset the clock, radio and any other accessories.

My 1994 park ave, sometimes it starts, sometimes it wont, it does not matter if is is hot or cold, when it is running it runs smooth like there's nothing wrong. I replaced most of the fuel system, spark...


You have three choices. First, check the spark and coil system to ensure you are getting a spark. Pull off a plug wire from the coil pack and crank. Have someone watch to see sparks snapping off the coil pack. If you don't have any replace the control module under the coil packs.

Second, you may not be getting enough fuel pressure. Put a gauge on the fuel pressure test port. You may have a bad oil pressure sensor, located down above the oil filter. Check that oil pressure sender and make sure the connector is pushed in. The power to the fuel pump runs through the oil sender. If the engine starts and oil pressure doesn't come up quickly, the computer will shut off the fuel pump. Check this and you can also manually engage the fuel pump from the relay block down by the passenger feet.

Third choice, and it's a long shot, check the harmonic balancer and the crank position sensor. If the sensor is bad, the computer has no idea when to fire the spark plugs. A magnet is on the harmonic balancer and flys by a sensor to induce a voltage in the coil and tell the computer what position the crank is in.

You also may have a bad computer.

You can figure it out.

When Im driving my car it shuts down while im driving. when i go to start the car it just turns over and doesnt start for awhile, i took a plug off and turned it over and there is no spark but it will...


It could be as you think....but it is more likly the crank postioning sensor...the 3.3's have this issue...by the way it's located behind your harmonic balancer so balancer removal is a must

Your Crank sensor is broken. You have to pull the Harmonic balancer off, it is behind it.
