If you are asking for the spark plug routing on a 2.8L V6, I can't post a diagram here but I will attempt to describe where the wires should be.
The firing order is 1-2-3-4-5-6. Cylinders 1,3,5 are on the side of the engine next to the firewall. Cylinders 2,4,and 6 are the front readily seen spark plugs. Numbers start at the crankshaft damper/serpentine belt end of the engine.
The spark plug wires go to the ignition module which is on the front of the engine down near the starter. The wires plug into the towers on the top of the coils. They are not in firing order. From your left to right they number:1-4-3-6-2-5
Hope that helps you.
what is the wiring diagram for an 1988 Chevy celebrity stero
There should be a vacuum line diagram on the passenger strut tower on your Celebrity.
There were no 1998 Chevy Celebrities made.
You can find the wiring diagrams for a Chevy Celebrity in either a factory service manual or either a Chilton or Haynes manual.
On some cars there is a sticker in the engine compartment with a belt diagram.
The signal flasher on all versions of the Chevy Celebrity is on the fuse block.
There should be a vacuum hose diagram on the front of the driver side strut tower.
I am presuming you mean the pcv valve, it is in the valve cover.
The firing order for a 2.5L 4 cylinder engine is: 1-3-4-2
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.
I am not certain what detail you are looking for but both my Chilton and Factory Service Manuals have the basic circuit diagram.
You can find a fuse block diagram in either a Chilton manual, a Haynes manual or a factory service manual.
