The signal flasher on all versions of the Chevy Celebrity is on the fuse block.
All 1987 to 1990 Chevy Celebrity engines use distributorless ignition. Timing is controlled by the engine control module in conjunction with the ignition module. There is no provision for adjustment.
The coils are bolted to the ignition control module, there is no coil wire as such.
There is no 1994 Chevy Celebrity. The Celebrity was discontinued in 1989, with the exception of the station wagon which remained in production through 1990. Assuming you mean 1984, depending on which engine it is, very easy or slightly difficult.
Timing on a 1987 thru 1990 Chevy Celebrity 2.8/3.1 engine is controlled by the ignition control module along with the engine control module. There is no provision or specification for manually adjusting the timing on these distributor-less models.
1990 was the last year a Celebrity was produced. It was as a Wagon ONLY, along with the Pontiac 6000. The celebrity was produced in a two and four door along with a wagon too. 1982-1983: coupes and sedans 1984-1988: coupes and sedans and wagons 1989: sedans and wagons 1990: wagons only
The last year Celebrity's were made was 1990, there was no 1994.
The 1990 Chevy Celebrity engine is distributorless, the ignition is handled by a combination of the engine control module(computer) and the ignition control module. You did not mention which engine the car has. If your car has the 4 cylinder engine the ignition control module is below the intake manifold at the rear of the engine. You can follow the spark plug wires to it. The coils are mounted to the ignition control module. If your car has the V6 the ignition control module is near the starter and again you can follow the spark plug wires to it. Again the coils are mounted to the ignition control module.
The turn signal fuse is in the fuse block. The fuse block is under the dash to the right of the steering column.
As I understand it all of the GM "A" body cars have the same roof line. That would be the Chevy Celebrity, the Pontiac 6000, the Buick Century and the Oldsmobile Cierra of the "A" body years 1982 to 1996?.
You need to be more specific. What sort of fuel problems does your Chevy Celebrity have?
The PCV valve on a 1987 - 1990 Chevy Celebrity is in the top center of the valve cover nearest the firewall.
