1997 Oldsmobile 88Sometimes my 1997 Oldsmobile 88 has problems starting with or without an engine check light. It has 184k miles on it. Once I start driving, sometimes it just stops accelerating and once it hits 0 MPH. I have to turn the car off and start the car back up to start driving again. Sometimes the steering wheel locks up during the deceleration. What is the problem with my car? Is it the fuel pump?


RESPONSE

Problems Starting

There is no simple answer for this one. If the check engine light has come on the on board computer will have stored a code. Possibly even more than one code. These diagnostic trouble codes are vital in diagnosing issues with the engine. The good news is that just about any local auto parts store will check these codes at no cost. Once you have the codes post them below for further information.

1995 Oldsmobile Cutlass1995 Oldsmobile Cutlass Supreme. After driving awhile, usually after around 10 miles, if I am stopped at a red traffic light idling, the car sputters to a stop. And then when I immediately try to start the car, the dash lights come on but there is no cranking whatsoever. I wait at the stop light about 3 minutes and then try to start the car again, it strongly cranks right up and starts. Then to keep car running at traffic light stops, I put the car in park and feed it a little gas until light turns green. I HAVE A THEORY! There is a wire (or wires) going to the spark plugs and the wire has lost part of its plastic covering insulation. That wire is intermittently touching metal in the car and grounding out or shorting out so that the plugs are not getting electric current. Please help.


RESPONSE

Your theory is a great place to start. Wrap some electrical tape around the exposed wiring and test it out. It will not hurt to try. If that helps, Replace the spark plug wires. Let me know how it tests out.

1984 Oldsmobile CutlassI was attempting to fix a leaking fuel line on a friends car but when i got under it and actually saw the line itself it was very clear that the whole line needs replacing. My question is can i use a nylon or vinyl fuel line to replace the current steel one? If so is there a kit you would recommend? I am unsure about what kind of fittings it would take to tie into the tank and the pump(which is on the block) or if i would need to actually pull the tank to accomplish this. Any advice will be greatly appreciated, thank you very much.


RESPONSE

The fuel line from the tank to the pump is a suction line and does not under go a lot of pressure. You could use rubber FUEL line and run it from the tank all the way to the fuel pump. Or you could use a mixture of metal line and rubber line. Use 2 hose clamps to attach the rubber fuel line to the metal line. It may be necessary to drop the tank to get to a usable metal line. No kit needed. Just purchase enough hose clamps and fuel line to do the job.

Fuel Line Hose Clamps

Removal of Fuel Tank

 

  • Disconnect the negative (-) battery cable.
  • Drain tank. WARNING 
    Have a carbon dioxide fire extinguisher near the work area.
  • Use a hand-operated siphon pump, and follow the manufacturer’s instructions for its use. As the fuel tank has a restrictor in the filler neck, connect the drain hose to the main fuel pipe at the fuel pump or at the tank gauge unit. Drain the fuel.
  • Reconnect any removed hoses, lines and cap.
  • Disconnect tank unit wire from connector in rear compartment.
  • Remove the ground wire retaining screw from the underbody.
  • Disconnect the hoses from the tank unit.
  • Support the fuel tank with a suitable jack and disconnect the two fuel tank retaining straps.
  • Remove the tank from the vehicle.To install:
  • On California emissions equipped vehicles, center the fuel filler pipe in the opening as required. Always replace the O-ring when the tank unit has been removed.
  • Support the tank with a suitable jack and position the tank into the vehicle.
  • Connect the fuel hoses and electrical connectors before installing the tank straps.
  • Install the tank strap bolt and nut to 96 inch lbs. (11 Nm) and the bolt-to-body to 26 ft. lbs. (35 Nm).
  • Connect the negative battery cable, refill the tank, start the engine and check for leaks.

1999 oldsmobile intrigueJust changed the alternator and belt. Now no heat coming from defroster and temperature gauge goes up right away. Any ideas?


RESPONSE

Wondering if maybe you installed the belt incorrectly and the water pump isn’t turning?

Generally this would be an indication of no coolant or low on coolant. Since it happened after you worked on it, I would double check your work first. Then check your coolant level.

2001 Oldsmobile Alerostarts but will not stay running


RESPONSE

If it will not stay running unless you hold your foot on the pedal, the most likely cause would be a sticking IAC – Idle Air Control Valve.

If the check engine light is on, by all means get the codes pulled and post them below.

Idle Air Control Valve Replacement

Removal Procedure

  1. Remove the throttle control cable bracket from the throttle body. Refer to Accelerator Control Cable Bracket Replacement .
  2. Remove the canister purge valve. Refer to Evaporative Emission Canister Purge Solenoid Valve Replacement .
  3. Disconnect the idle air control (IAC) electrical connector.
  4. Remove the idle air control valve attaching screws.
  5. Remove the idle air control valve.
  6. Remove the idle air control valve O-ring.

Installation Procedure

 Caution! The IAC valve may be damaged if installed with the cone (pintle) extended more than 28 mm (1-1/8 in). Measure the distance that the valve is extended before installing a new valve. The distance from the idle air control valve motor housing to the end of the idle air control valve pintle should be less than 28 mm (1-1/8 in). Manually compress the pintle until the extension is less than 28 mm (1-1/8 in).
IAC 2001 Oldsmobile Alero
  1. Install the new idle air control O-ring.
  2. Install the idle air control valve into the throttle body.

Caution! Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

 

  • Install the idle air control valve attaching screws.

 

Tighten
Tighten the screws to 3 N·m (27 lb in).

 

  • Connect the IAC electrical connector.
  • Install the canister purge valve. Refer to Evaporative Emission Canister Purge Solenoid Valve Replacement .
  • Install the throttle control cable bracket. Refer to Accelerator Control Cable Bracket Replacement .
  • The powertrain control module (PCM) will reset the idle air control valve whenever the ignition is turned ON, then OFF. Turn ON the ignition, then OFF.
  • Start the engine and allow the engine to reach operating temperature.

1991 Olds CutlassI just replaced head gaskets. I get it back together have no spark. I cant get OBD codes. I jump pin a to b but there is no wire on b. Tried two that are there and nothing. I changed cam and crank sensors. Can u please help I’ve been trying to start for a week none stop. I really need this car to start. OMG thanks.


RESPONSE

If it ran before you worked on it, go back over your work and look for something unplugged. Look a the wiring to see if any wires are pulled from a connector. Double check your work.

There is a chance that your vehicle was built in late 1995 making it a ’96 model as far as computer systems go. This would make it an OBD II System and would require a scan tool to pull the codes. Most auto parts stores will do this for free. Unfortunately yours does not run so it will require some basic diagnostics to start off.

You will need to determine what the engine is not getting. If it is not getting spark or injector pulse, check ECM fuse if good replace ECM(since you already replaced the crankshaft and camshaft sensor) If you are getting injector pulse but no spark, replace the ignition control module. These are the most common part failures for this year.

How to remove steering wheel with Air Bags

WARNING 
On vehicles with air bags, disable the SIR system. The vehicles wheels must be in the straight ahead position and the key must be in the LOCK position when removing or installing the steering column. Failure to do so may cause the SIR coil assembly to become uncentered and may result in otherwise unneeded SIR repairs.

  1. Disconnect the negative battery cable.
  2. Properly disable the SIR system, as outlined in Section 6 of this manual.
  3. Make sure the ignition is in the  OFF position. CAUTION 
    When carrying a live air bag, make sure the bag and trim cover are pointed away from the body. In the unlikely event of an accidental deployment, the bag will then deploy with minimal chance of injury. In addition, when placing a live air bag on a bench or other surface. always face the bag and the trim cover up, away from the surface. This will reduce the chance of personal injury if it is accidentally deployed.
  4. Remove the air bag inflator module, as follows:
    1. Loosen the bolts or screws from the back of the steering wheel, using the proper Torx® driver, until the inflatable restraint module can be released from the steering wheel.
    2. While pulling the module away from the steering wheel, detach the SIR coil electrical connector and remove the retainer from the module.
    3. Remove the horn and ground lead from the steering column.
  5. Scribe an alignment mark on the steering wheel hub in line with the slash mark on the steering shaft.
  6. Loosen the steering wheel nut, positioning it flush with the end of the shaft.
  7. Assemble steering wheel puller J 1859-03 or equivalent, on the steering wheel hub with two  5 16 –18×4 in. bolts. Break the steering wheel loose from the shaft.
  8. Remove the steering wheel puller.
  9. Remove the steering shaft nut.
  10. Remove the steering wheel from the vehicle.To install:
  11. Route the SIR connector through the steering wheel.
  12. Align the scribe mark on the steering wheel with the slash mark on the steering shaft and install the steering wheel.
  13. Install the steering shaft nut and tighten to 30 ft. lbs. (41 Nm).
  14. Install the air bag inflator module, as follows:
    1. Connect the horn and ground lead to the column assembly.
    2. Attach the SIR coil assembly electrical connector and retainer to the module.
    3. Secure the SIR coil assembly electrical connector to the steering wheel assembly by inserting the thick section of wire into the existing retainer.
