2006 Oldsmobile 88 - Answered Questions & Fixed issues

Unless you can find a diagram for the location of the relays... unplug them one at a time... till you find the one that controls the lights

It sounds like you have ruled out some common causes for the starting issue with your 1992 Oldsmobile 88 Royale. If the battery, terminals, solenoid, starter, and alternator have all been checked and are in good condition, there are a few other things you can try to troubleshoot the problem.

1. Check the fuel system. A faulty fuel pump or clogged fuel filter could cause the engine to not start. Check the fuel pump and fuel filter and replace them if necessary.
2. Check the ignition system. A faulty spark plug or ignition coil could cause the engine to misfire and not start. Check the spark plugs and ignition coils and replace them if necessary.
3. Check the fuel pressure. Low fuel pressure can cause the engine to not start. Check the fuel pressure and make sure it is within the manufacturer's specifications.
4. Check the engine temperature. If the engine is overheating, it could cause the engine to not start. Check the engine temperature and make sure it is within the normal range.

If you have checked all of these things and the problem persists, it is possible that there is an issue with the engine itself, such as a problem with the valves or cylinders. I recommend having a mechanic diagnose the problem in order to determine the cause and recommend the appropriate repair. I hope this helps! Let me know if you have any other questions.

It sounds like you are having a problem with your 1999 Oldsmobile Delta 88. The issue you described, where the engine starts and then shuts off after a few seconds, could be caused by a number of things. Here are a few things you can try to troubleshoot the problem:

1. Check the fuel system. A faulty fuel pump or clogged fuel filter could cause the engine to shut off shortly after starting. Check the fuel pump and fuel filter and replace them if necessary.
2. Check the ignition system. A faulty spark plug or ignition coil could cause the engine to misfire and shut off. Check the spark plugs and ignition coils and replace them if necessary.
3. Check the fuel pressure. Low fuel pressure can cause the engine to shut off shortly after starting. Check the fuel pressure and make sure it is within the manufacturer's specifications.

It sounds like you are experiencing a problem with the Rochester 2GC carburetor on your 1957 Oldsmobile. The issue you described, where the engine is difficult to restart after it has been shut off for a period of time, could be caused by a number of things. Here are a few things you can try to troubleshoot the problem:

1. Check the fuel level in the carburetor bowl. If the fuel level is too low, the engine may not start. Make sure the fuel level is at the proper level and that the bowl is not leaking.
2. Check the float level. The float in the carburetor controls the fuel level in the bowl. If the float is set too high, it can cause the engine to flood when it is restarted. Adjust the float level according to the carburetor manufacturer's specifications.
3. Check the fuel pump. The fuel pump supplies fuel to the carburetor. If the pump is not working properly, it could cause the engine to flood or not start at all. Test the fuel pump and replace it if necessary.
4. Check the fuel lines. Make sure the fuel lines are not clogged or damaged. Replace any damaged or clogged fuel lines.

I hope these suggestions help! Let me know if you have any other questions.

There are a few options you can try to find this information:

1. Check the owner's manual for your car. This should have a section on the vacuum diagram and other technical information about your car.
2. Contact a Oldsmobile dealership or an auto parts store and ask if they have a copy of the vacuum diagram for your car.
3. Search online for a copy of the vacuum diagram. There are many websites that provide technical information and diagrams for various makes and models of cars.

I hope this helps! Let me know if you have any other questions.

Starter relay is on the starter motor, and the fuse box should be under the dash, in the drivers feet well.

Your best bet , take it to a qualified repair shop.

What engine. ? Did you try pressing on the gas a little to see if it will keep running ? You get no codes ? You know how to do the flash code test ? Clean the throttle bore an idle air control passages . Have you changed spark plug's & wire's ? Ever ? Fuel filter

It's probably still a problem with the ignition control module/coil, with a circuit in or attached to it heating up as the engine warms, and then the circuit opens when stopped and it starts to cool. As soon as the engine sufficiently cools off, the circuit would revert to a good connection. I would carefully check the connectors and wiring on both sides of the module, and then possibly trying another module.

Remove airbag fuse. Disconnect battery. Remove two/4 screws (usually Torx-forget the size but rather large maybe T7) from the back side of the steering wheel. Remove airbag assemble . Carefully disconnect the harnesses. Remove the large steering wheel retaining nut. Using a steering wheel puller remove the steering wheel. At this point you may need to remove the shroud from the steering column. Usually t 10 or T15 screws. Remove retaining screws from the multi function switch. Carefully un plug and remove. Installation is reverse. Highly recommend a haynes or Chilton repair manual for this job. Steering wheel puller can be rented from most auto parts chain stores.

I think all the relays are in the main fuse block. Note: there is also a temp sensor in this circuit=common part to fail.

The Internet, though, has a large number of web sites where you can buy service manuals and schematics from bookstores, publishers, and other collectors. Here is just a sampling of what sites are out there: Chilton Repair Manuals http://www.chilton.cengage.com/ Factory Automanuals http://www.factoryautomanuals.com/ web based auto repair manuals Haynes Publishing http://www.haynes.com/ Vintage Books http://www.vintage-books.com/ AutoLit.com http://www.autolit.com/home.htm RepairManual.com http://www.repairmanual.com/

Unplug the 3 wire electrical connector, remove the retaining bolt or screw, pull sensor out of the timing chain cover. It's above the crank sensor on left side of timing cover.

as another here said ..... locate your evaporator inlet outlet lines usually coming out of the fire wall. then follow the line that runs to the compressor. that is your low side line and the service port should be on that line

set the fuel pressure on the regulator. its in the fuel line in the engine compartment

NO--- if the surfaces were clean and dry prior to refitting and a quality sealant was used then when the pump is in then water can be added right away as the sealant is between the surfaces and water cannot get to it to displace it.

Bad idle control valve is the most likely problem. They carbon up and stop working. Take it off the car and clean it with brake cleaning spray or parts cleaner. Do a good job. Replace and it should be fine. They don;t "wear out," but they do gum up.
