What is the firing order?

Hello,

This engine only has one coil which feeds the distributor. If your vehicle has two ignition coils, then you are working on a 1997 model.

The firing order is the same, 1-3-4-2 with cylinder 1 being nearest to the timing belt.
See image one below.
On the vehicle using two coils the left coil fires cylinder 1+4 and the right coil, further back, fires cylinders 2+3. The coils are marked.

If the engine has a distributor, then the camshaft position sensor is located inside the distributor.

The later model has the camshaft position sensor located near the from camshaft pulley.
See image 2+3 below.

Cheers, Boris
