Where is the IAT sending unit on a 1991 Chevy Corvette and how many wires does it have?

The AC power relay is located behind the right side of the dash on a 1991 Chevy Corvette. It is on top of the plenum.

in back on top by distributor, or down on driver side engine block on the side by the bellhousing, look for wires and round unit threaded into the block.

The oil temp sensor on a 1991 Chevy Corvette is located on the bottom of the engine, near the oil pan. It constantly monitors the temperature of the oil and relays information to the computer.

Mounted next to the oil filter.

Sounds liek a job you may need some real help on so...I

check the coolant temperature sending unit on a V8 it is in the front of the intake manifold

1,8,4,3,6,5,7,2 same as the firing order

German corvette Hiddensee was created in 1991-11.

German corvette Hiddensee ended in 1991-04.

All V8 Chevrolet's are 1,8,4,3,6,5,7,2 with 1,3,5,7 on the left bank and 2,4,6,8 on the right with the distributor rotating clockwise.

Protects the wireing in case of a short, the fuse will blow insted of the wires melting.

Most 1991 sending units on a 1991 Le Sabre screw in. The exact location for the sending unit will depend on which one needs changing.

it doesnt sound orthodox but cut the tach wires to the dash, it worked on my 94 with a 350.

4.3? Follow the spark plug wires from the spark plugs, they will lead you right to the distributor.

where is thecarburetor in my 1991 Chevy caviler

if it is a V8 it is 18436572

check fuses. check bulbs. check wires. If not any of those, good luck.

if it is an 350 eng it is located at the rear of the intake manifold,on the top of the block, next to the dist.

Check for power and ground at the tank. If it is okay then the sending unit is most likely the cause.

There is no such thing as a 1991 Chevy Celebrity

No. The 91 Corvette has a larger roof panel than the 88 Corvette's. yes if you change the front anchoring brackets

all v-8 Chevy is 1 8 4 3 6 5 4 2

There is no trunk release on a 1991 Chevy Caprice.

regulates the fuel pressure.

IF IT IS A 4 CYL YOU PROBABLY HAVE A BAD CRANK SENSOR OR IGNITION MODULE.
