20 Most Recent 1990 Buick Century Questions & Answers

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.

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?

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 !

The dash and tail lights are on two different circuits, and the brake and turn signals are on different circuits, so at least 4 circuits total. I would start at the headlight switch and check for power on the first two issues.

open hood look for the light assembley powercords that go into the headlamp..turn right or left to loosen ... you may have to just take a screw driver and remove the cover over the signal light. press in and turn and replace.

What was wrong,bad battery or bad alternator?

If you take the car to Pepboys, Auto Zone or just about any other parts store they will read the codes out for you and happily sell you the parts to repair it.

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.
