WARNING
Use extreme caution when the engine is operating.
Do not stand in a direct line with the fan. Do not
put your hands near the pulleys, belts or fan. Do
not wear loose clothing.
Disconnect an injector wire harness connector for a
moment, then reconnect it. Repeat this on each of
the other injectors.
A loss of engine speed should be noticed while each
injector is inoperative.
If anyone cylinder is not firing because of an
inoperative injector, switch the wire harness
connectors between the inoperative injector and one
that is working.
If the previously operational injector does not work,
the wire harness is faulty.
