Technician a is correct. All the fuel injection on an engine should have the same electrical resistance.
Fuel injection refers to the introduction of fuel using an injector into an internal combustion engine, most frequently an automobile engine. In reciprocating piston and Wankel rotary engines, fuel injection is the main topic of this article.
Fuel injection of some sort is used in all compression-ignition engines (such as diesel engines) and many spark-ignition engines (such as petrol engines like Otto or Wankel). The earliest fuel injected engines for use in passenger automobiles were mass-produced diesel engines for cars (such the Mercedes-Benz OM 138) that were made available in the late 1930s and early 1940s.
Fuel injection was first used in passenger car petrol engines in the early 1950s, and it steadily gained popularity until, by the early 1990s, it had virtually supplanted carburetors.
