  1. Four cylinder engines also have the #1 cylinder closest to the leading in the engine (only one banking institution).
  2. V-6 or V-8 try to find the connect that is nearest to the top of your engine, when the cylinder heads are even an alternate means of identifying #1 will be required.
  3. Don’t overlook the obvious, check up on the spark connect cable on its own for cylinder phone numbers.

  5. If you have a check resource, consider disconnecting an oxygen detector in the short term to find out which is B1 or B2. Commonly a pending code or tough code sets quickly. Also glance at the information display screen of the check tool, the voltage must typically default to .5V.
  6. If all else fails look at the assistance manual. Numerous on-line sources offer easy access to firing order and a lot more at DIY pricing.
