What is the firing order for a 1985 bluebird Nissan 4-cylinder with 8 leads?

A 1985 Nissan Bluebird with a 4-cylinder engine and 8 leads likely has a distributor with dual ignition coils, meaning each spark plug has its own coil firing individually. Therefore, a specific firing order isn't as critical to find as with a single coil distributor.

However, the engine's firing order is still relevant for proper engine operation and diagnosis. To find the precise firing order for your specific engine (as different engines were used in the 1985 Bluebird), you should:

1. Check your engine's identification number: This number, usually found on a plate on the engine block, will help you identify the exact engine model.

2. Consult a Nissan workshop manual: These manuals provide detailed specifications, including firing orders, for each engine. You can often find these online (often for a fee) or at a parts store.

3. Look for markings on the distributor cap: Sometimes, the firing order is marked directly on the distributor cap itself.

Without the exact engine code, it's impossible to give you the correct firing order. Standard 4-cylinder firing orders are 1-3-4-2 or 1-2-4-3, but your engine might not follow either of those.
