Which is the correct definition of ignition timing?
Ignition timing refers to the point at which the spark plugs ignite the fuel within an engine’s cylinder.
What happens if you have an incorrect ignition code?
The chip in the key transmits a specific code, of which there are millions. If this code matches the ones programmed into the vehicle, engine starting is enabled. An incorrect key code, such as from an unprogrammed key or damaged key, would prevent engine starting. Code “confusion,” such as having multiple keys can also occur, preventing ignition.
What happens when fuel is ignited at the same 10 degree timing?
As the engine rpm increases to 3,000 rpm, the fuel, — still requiring the same time to burn — would never have sufficient time to burn if ignited at the same 10-degree timing. In order to have the same result, the fuel must be ignited much sooner in the compression stroke.
Where is the optical sensor on the OIS 2000 ignition?
The OIS 2000 ignition has to have the power coil supplying power in order to operate the QuickStart, S.L.O.W., rev limiter, and fire the coils beyond cranking speed. The optical sensor located on the top is fed power from the power pack and sends crankshaft position, cylinder location and direction of rotation back to the power pack.
Can a bad sensor prevent a car from starting?
There are many reasons why damaged sensors would impact the engine starting process such as: Faulty sensors can keep your engine from starting, but this is often engineered in as a safety measure. Dirty sensors will impact whether your vehicle starts. Preventing engine damage is another reason that a sensor fault can cause a hard to start problem.

When did Johnson 60 degree ignition system come out?
We have chosen to narrow this troubleshooting guide to the Johnson/Evinrude 60° 6-cylinder ignition (OIS 2000) 1991-2003 model years. Due to the differences in this ignition system, troubleshooting can be somewhat difficult if you are not familiar with the design.
