FUEL INJECTOR
IMPORTANT: Never mix up fuel injectors of
naturally-aspirated and supercharged 4-TEC en-
gines. Doing so will automatically lead to a
misfunction of the EMS and will cause a bad
engine calibration.
Leakage Test
To perform a leakage test, the injectors and fu-
el rail have to be removed from the engine. See
FUEL INJECTOR REPLACEMENT below for the
procedure.
NOTE: Do not detach injectors from the fuel rail.
Reconnect the fuel line and the wiring harness.
Place each injector in a clean bowl.
Install the safety lanyard cap on the DESS post to
activate the fuel pump.
Check for fuel leakage from the injector nozzle.
There should be less than 1 drop per minute. Per-
form the test for 2 minutes.
If not within specification, replace the fuel injec-
tor(s).
Properly reinstall removed parts.
