K 2500 Suburban 4WD V8-5.7L VIN R (1999)
Fuel Injector: Description and Operation
Testing of the fuel injector circuit is located in the Fuel Injector Circuit Diagnosis Table.
A fuel injector which does not open may cause a no start condition. An injector which is stuck partially open could cause loss of pressure after sitting,
resulting in extended crank times on some engines. Also, dieseling could occur because some fuel could be delivered to the engine after the key is turned
OFF.
