2002 Oldsmobile IntrigueI have a 2002 Oldsmobile Intrigue that started with the heater blower not working and now it won’t start. Found a blown fuse for the high blower and replaced it. I even replaced the starter that looked old. The headlights are bright and the radio/dash seem to be strong as well. I have tested all of the other fuses with a test light and all seem fine. Seems to be electrical but can’t pin point the problem. Also, jumping the car doesn’t work either.


RESPONSE

Jumping the car doesn’t work

Jumping a car rarely works after a battery has been run completely flat. Your vehicle had a short in the system and is why the fuse was blown and may have also run the battery flat. The most common reason for a no start is the battery. Either bad connections or the battery itself. If the battery is close to being 4 years old, replace it anyway. It takes very little amperage to operate the radio(5 amps) or the lights(7 amps) as compared to the 250 amps needed to turn the starter motor. You can check for battery voltage at the “S” terminal at the starter when someone holds the key in the “START” position to check the circuit.

Still Won’t Start

There is the possibility of an electrical issue in the starting circuit. Start with a fully charged battery. Check for battery voltage at the involved fuses. Check for output voltage at the starter relay. Look for voltage going to and from the neutral switch. Repair the wiring in between if any loss of voltage is indicated. Use the starting system wiring diagram for reference.

2002 Oldsmobile BravadaThis vehicle has automatic 4×4 BTW. When driving and turning the wheel, the vehicles slows down and rear tires slip as if grabbing for traction. Also, there is a hum or whine while turning and lasts for a few seconds while straightening and going forward. There are no lights on the dash at all. Just replaced the camshaft position sensor. Any help you could give would be great.


RESPONSE

Whine noise when turning

A hum or whine noise sounds like a bearing going out. These vehicles are known for hub bearing failure. Drive at a around 10 to 15 mph and sway back a forth slowly. Listen for the noise to change pitch. If it does this is most likely what the problem is. A failed hub bearing.

Hum Noise

A him noise from the rear probably indicates a defective rear axle, especially if it is louder when coasting. Check the rear axle oil level.

1995 Oldsmobile Cutlass CieraI replaced my starter and when I tried to start it kept trying after key was off. It is a 19995 Oldsmobile Cutlass Ciera SL.


RESPONSE

Starter Stuck On

This is common when the terminal ends get tightened up and touch. If this is not the case you can remove the smaller wire from terminal “S” and test for constant voltage with the key “OFF”. If there is voltage found, trace back through the selector switch and finally the ignition switch. No voltage found, make certain the big wire isn’t near or touching the small wire, reattach and test again. If the issue reoccurs you may need to replace the starter as the replacement is shorted internally(not common at all). Since you made need a wiring diagram to understand the circuit I have provided one.

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.

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).

  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.
