This is a pretty big job, but not as bad as trying to add fuel injection to a car that came with a carb. Pull out the injected engine along with the on-board computer and harness. It might have value to someone in the used parts business. Install the carbureted engine with the factory mounts. You'll need a switched 12V source for the hot side of the coil, electric choke (if applicable), and the exciter wire on the alternator. You'll need constant 12V for the big post on the starter. You'll need a 12 guage wire connected from the other two terminals on the alternator to the big post on the starter solenoid. You'll need a wire from the start circuit of the ignition switch to the inside post on the starter solenoid. You'll either need a mechanical fan attached to the water pump or an electric fan wired to a thermostat set to come on above 180 degrees. If any of the lights or other 12V accessories don't work as a result of removing the power source, you'll need to provide a power source. Take care to note if the power source is available all the time or only when the ignition switch is on. If the transmission requires input from the on-board computer, you might be able to search the aftermarket for a solution. Summit Racing Equipment can be very helpful in this area. I've probably forgot one or more things that would need to be dealt with individually. Good luck.
cause its throttle body injection theres no carb on it its probly your fuel pump is gone
87 Caprice uses Throttle Body Fuel Injection. To put a carb on it will also require changing the distributor and fuel pump and disabling the computer. This will eliminate your cruise control and possibly mess up your speedometer.
Assuming you have a 305 V8 with a Rochester Quadrajet carb. You will have to pull the carb, and tear it apart. The TPS sits in a groove in the front of the carb body. Buy a carb rebuild kit, watch the Youtube videos on rebuilding quadrajets, and do it. I just rebuilt my carb over the weekend. My 83 Caprice now runs great.
Change the intake manifold and fuel pump. Install the carb, and you're done. I'd recommend against the swap if there isn't anything seriously wrong with the fuel injection though. Electronic fuel injection (especially port injection like the 88 Camaro has) is superior to carburetors in every conceivable way. Better performance, better mileage, etc. If you are building up the engine, you would be better off remapping the fuel table of the EFI to match what you have done to the engine than you would be bolting a carb on it.
Your 1990 would have throttle body injection, not a carburetor.
first install new carb gasket to intake manifold and then 4 nuts hold the carb to the intake studs and then install the throttle linkage to the carb.
Butterfly at the top of the carb. Controlled by Round black box at side of the carb. (Temp. sensitive)
It is fuel injection, no carb.
Need more info Model Year Carb TBI throttle body injection or MPI multi port injection
It's located in the top part of the carb
on my 87 Chevy caprice just happen today, my car would idle for a while then die. Turns up my carb was bad. Changed the carb, ran like new again.
yes it will you would use the intake and carb and you would loose the fuel injection un less you swap heads
You have to have the computer for the throttle body carb and the fuel pump to match it good luck
These days all cars come with fuel injection. Cars with fuel injection do not have a carb. They do have a throttle body, which controls the air entering the engine, but unlike a carb, do not meter the fuel at the same time.
Most '86 Caprice engines were fitted with a four barrel carb which requires occasional adjustment to keep idle at reasonable speed.
throttle position sensor located in the top part of the carb
I fuel injection its underneath near fuel tank, if carb it doesnt have one however depends on the carb type, it may have gauze filter in inlet on carb.
the fuel filter is on the carb. you have to take off the fuel line
carb, cam, intake, headers, heads, msd igntion, or a 350
Adjust your carb, otherwise, it's a problem with gas getting to the carb while accelerating.
You attach the carb to your runners, and reroute your accelartor cable to the carb. You will also need a different fuel pump, one rated about 3lbs as the stock fuel pump is for fuel injection. Brian Minson, Editor Porsche 9 Magazine www.9magazine.com
You may need to adjust your idle speed or timing.
1991 5.7 police package car should have throttle body injection - fuel filter located in passenger side frame rail. If it is a carb, its probably a quadrajet, just remove the fuel line where is screws into the carb, and there will be a little fuel filter. Should also be another along the fuel line somewhere.
