1990 Buick Century - Answered Questions & Fixed issues
I need to change the head unit in my 1990 Buick Century, but the wire harness the mechanics gave me doesn't fit?
The connectors for all GM oem radios for this car/year are the same. The place that sold you the new radio should be able to provide a patch cable with a connector at one end that fits the aftermarket radio, and one or more connectors at the other end that fit into the connectors in your car. If you can't get that patch cable from them, try sonicelectronix.com. These cables are usually unique to the brand of your aftermarket radio. Although it's a bit late, It's a good idea to check that these patch cables are available from the seller before buying the radio.
If you can't find a patch cable and the cable that came with the new radio has no connector(s) on one end, you will need to splice those wires to the correct wires going to the old radio connector, and for that you will need the wiring diagram for both your car and the new radio. You should be able to get the wiring schematics for your car from Alldatadiy.com, and your new radio should have come with a connector pinout description.

How can I replace starter?
www.autozone.com
should have this info, you can probably read it faster than I can write it. I'm not sure of engine size?
On the site you need to register your vehicle, then in the site search box, upper left, type in, "starter", then on right side of page should be a link for starter removal/installation, The info may be different depending on the engine size.
It's all free.

1988 buick century dies when put in gear
Sounds like the lock up torque convertor in the transmission is stuck in the engaged position.There is a sensor switch under the hood that can be temporarily unpluged but leaving it unplugged can ruin the transmission. Take it to a tranny shop.

Replaced fuel pump,strainer,fuel filter,battery,computer,car will only start when you pour gas down air intake.
Sorry this vehicle does not have a fuel shut off switch or inertia switch > that's ford ! If you pour fuel in the throttle body an it runs It's something with the fuel system , an if you replaced the pump an filter an regulator , It has to be electrical ! did you check voltage at the fuel pump relay ? What engine does yours have , 2.5 , 3.3 L ? There is a in line fuse for the fuel pump near the relay ! There are four relays front right of engine compartment mounted on radiator support cross member . The one for fuel pump is the one on the inside . Fuse is near there an there is a connector not connected to anything ,this is for fuel pump prime . Jump battery voltage to it a see if it runs then ! or replace relay !

Why does the ctsy fuse keep blowing
Fuses blow for one reason only. There is a short somewhere in that circuit. Make sure to check everything that's powered through that fuse.

IF I HAVE BAD GAS IN CAR WHAT WILL IT DO?
the gas in New Zealand in our 91 octane is 80% tolulene which is an industrial solvent, it goes off after six months, makes the engine hard to start,if at all. the engine might not run on all cylinders, the gas fouls the spark plugs. i have had to drain tanks and fit new hotter heat range spark plugs to fix some engines.
