Once you know the engine displacement, you can:
1. Check your owner's manual: This is the most reliable source. The firing order will be clearly stated.
2. Look under the hood: Sometimes a sticker indicating the firing order is located on the engine or the inner fender well.
3. Use an online resource: Search online using "[your engine displacement] 1994 Chevy Malibu firing order". Websites specializing in automotive repair information may have diagrams.
4. Consult a repair manual: A Haynes or Chilton repair manual for your specific year and model will provide the firing order.
Without knowing your engine size, I cannot give you the correct firing order. Providing the wrong order can damage your engine.
