According to my info there isn't one. There should be a fitting or something on the end of fuel rail, then you use an adapter and pressure gage for that adapter. You may have to get fittings and adapters from your local dealership. I tried looking up the part numbers, online search, I didn't see it. The part numbers are, j34730-1a--gage----- j3470-262-fitting. Maybe you can find the numbers? There may be another way to check fuel pressure, but, I can't see anything from here. Don't want to cause additional problems.

This might help:

Google, or library usually has repair manuals with diagrams.

Probably bad bearings somewhere. could be constant velocity joints, Transmission oil level, even bad wheel bearings.

the reason of tapping could be: a) a low quality gasoline with low octane rating below 98/95 b) wrong adjustment of carburetor c) valves need adjustment d) high mileage on the engine

Check fuel filter, pump pressure , MAP sensor

you will probably find it easier if you just take out the clocks and unplug the loom from them then its just twist and turn the bulb out find a replacement and hey presto

this isn't something I would recommend unless you have extensive mechanical experience as you'll have to carefully disconnect plugs on the back side of the instrument panel... plus isn't that a digital dash ???

I am only guessing without seeing it, could it be the ones for the transmission?
Located near the front side of the engine, to the drivers side?

Can't help you on this directly, but you should be able to find the schematics for your car on a site called ebsco.com. You need to be a paid member to access the site. However, most libraries have accounts. Go to your local branch and look it up using their system. Using it from there will be free. If you have a library card you can sometimes get online access from your home computer by using your card number and the u/n the library provides. Call them and ask, it may save you a trip.

Because that is the only kind or type done, in the last 25 years Google what it is & all the reasons for wheel alignment Most vehicles have adjustments in the rear, as well as the front, or parts that can be changed to make adjustments,depends on the vehicle platform design

Their are two fuse panels one is under the hood, right behind the battery, the other is accessed by opening the passager door and removing a side dash panel... not sure where the headlight fuse is but hope this helps

Why would you not have the key cylinder replaced, if that is even the problem ? That makes no sense to use a car like that Now your new battery will go dead & be ruined

If you have the 3.1 engine, that is a very common issue. Nothing to worry about if it indeed does go away. It's when the noise continues that you need to be concerned.

change your thermostat it may not be opening all the way

Check air filter,clean throttle body,could be TPS sensor,the last IAC sensor.

Depends how fast is idle but it could be normal when a/c is on idle should raise and cooling fan on hope it helps

Fuse probably.

There are some resistors on your cluster circuit board that have corroded and thus, no longer making a good connection for PRNDLL/odo display. This is a common issue with 1997-2004 Buick Century/Regals. Look for a gauge repair service in your area or on the web. Good luck. Ron @ Speed-O-Repair

Put the key into the ignition and turn it to "Run." Don't start the engine. Press down slowly and fully on the gas pedal, then release it. Do this three times in five seconds. Watch for the "Service Engine Soon" light to start blinking. This indicates that the system is resetting itself. Turn the ignition to "Off" and wait one minute. Start the Century's engine. The Service Engine Soon light will flash for a moment, then turn off. If it doesn't do this, repeat the process.if all else fails...Disconnect your battery for one minute and then reconnect it again that should reset it, if the problem that you have in your car is still there then that light will come on again after whille then you gona need to run diagnostics on your car to find the problem if it will not come on again then that should take care of it.9-08-2006Let me tell you about my experience with my 1995 Buick Century.When my buick sits for a while while running, the radiator fan comes on, you know?Well, after the fan does its thing, SOMETIMES the "SERVICE ENGINE SOON" light comes on.THEN.....when this happens again, it may take a couple times of after the fan comes on, then....the light goes off !!!Its like it needs to go thru some sort of "CYCLE" , THEN THE LIGHT GOES OFF...Who knows though,you may have LEGITIMATE problems with your car.good luck.
