Unable to do emissions test, just installed new battery 2 days prior
Once the computer looses its memory, the car has to be driven under several different conditions before it has stored the necessary info for the emissions test.The loop includes city driving, highway driving, and more than one or two stops with the key off. The engine has to be at operating temp too. Usually 50 - 100 miles of each will do it.
Replace fuel pump
I believe that all of these cars have an access in the trunk. On my regal the back seat folds down. I was able to then pull up the carpet in the trunk, close to the back seat, and have access to the pump cover. If you back seat does not fold down, you would have to do all of the work through the trunk. There are some great videos on youtube for this. It took less time that I expected. I was very methodical and double checked everything and it took me about 45 min. I could probably do it in under 30 min a second time.
The dash lights for odometer and gear indicator is out
maybe but sounds like a couple of lights have burned out,. the owners manual should tell you where the fuse box is located. The dash light for the odometer/gear indicator may be accessible from under the dash, get an auto maintance repair manual from the local auto parts store , perfably a chiltons for about 20.00. It will help u loctae the dash lights and the fuse box more readily.
Driving through water
You'll have to treat it like any other no start condition.Check for spark at the plugs and fuel pressure at the injectors.
Cant resolve a blinker issue, Tried the easy stuff.
The signal wire going to the right front has a splice for the dash indicator, a wire branching off from the turn wire and going to the dash. It sounds like that right signal wire is broken or lost a connection before it splices off to the dash, so the problem sounds like it is under the dash, either coming out of the turn signal switch to the flasher or from the flasher to that splice. You may need a multi-meter to check voltages on that wire at various places under the dash. Ascertain which color wire you need to concentrate on. Check for voltage on it with key on and right blinker on-voltmeter will spike to battery voltage, then fall to zero as the flasher breaks voltage continuously, if checked after the flasher. If checked when leaving the turn switch, it should be a continuous signal on that wire. Think you better find a wiring diagram to find the right wire to check. Good luck.
The odometer display is out...how do I fix?
This may be something that you don't want to tackle yourself, unless you are OK with electronics. You have to pull the gauge cluster, take it apart, and solder in some new resisters. In the top left hand corner of cluster, by the reset button, there are four resistors. They are something like 150 or 180 ohms. I would de-solder all of them and put all new ones in. Once again, don't tackle if you are not comfortable with electronics and solder.
My 89 buick century 2.5L is hard to start
-You mean. crank 3-4 times before it fire...?If so. Possibly dirty injector, low fuel pressure.-Or you mean you turn the key 3-4 time before the starter crank...?If so. Solenoid has dirty contact or bad connector.Mai
Engine runs rough when idling
Check the firing order, The push rod has 2 differnent sizes for intake and exhaust, If they get switch you get the rough idle
