Checking my injectors basics
While an engine is running you should be able to
hear each injector clicking as the electronic valve opens and
closes. To aid in this inspection use a stethoscope and touch it
against each injector.
Remove the injector electrical connector, turn the key to the on
position without starting the engine. This test will tell you if the
computer has proper system voltage and injector trigger signal.
Remove an electrical connector from a fuel injector. Probe both
sides of the connector with a grounded test light or multimeter
(voltmeter). Set the voltmeter to DC voltage. Have a helper turn the
key to the "on" position without cranking the engine and observe.
The test light/voltmeter should illuminate/read one side of the
connector. The multimeter should read about 12 volts. Next, switch
the test light or multimeter (voltmeter) lead (black) or to the
positive side of the battery to test the system ground injector
trigger. Disable the ignition system so the engine will not start
(disconnect ignition coil or remove the ignition fuse). Probe the
side of the connector that did not light up in the previous step,
have a helper crank the engine over and observe the test light, it
should blink on and off or the multimeter (voltmeter) should bounce
from 0 to 12 volts. (Note: if no injector pulse is present try
disconnecting the remainder of injectors and re-test, if a fuel
injector is shorted it can shut down the injector driver causing no
injector pulse. If injector pulse returns plug the injectors in one
at a time until the pulse fails. Replace effecting injector). If
this test is positive and the injector still will not operate the
injector has failed and replacement is required.
While the injector wire connector is off, test the fuel injector
windings by setting the millimeter (voltmeter) to ohms and attach
the leads to either side of the injector. Your reading will vary
depending on manufacturer. For the exact ohms reading a car repair
manual is needed. Test all of your injectors; if one injector
reading is considerably different from the others replace the
different injector.
Check the fuel pressure regulator, remove the vacuum line feeding
the fuel pressure regulator, check for the presence of fuel, if fuel
is present the diaphragm inside the regulator has ruptured and is
feeding raw fuel into the engine causing it to run rough.
