How do you test the fuel injectors 2.2L DOHC 2002 chevy cavalier?

my car died on us like 20 times tryin to get home. it sounds like it's not getting enough gas or it's running out of gas. i know it's not out of gas. it was also backfiring and going 10 MPHs. Just changed the fuel pump, fuel filter, air filter, spark plugs, oxygen sensor(bank 1). Is it possible dirt, or something might have gotten by the filter before and clogged the line from the filter to the injectors? or are the injectors bad?

Test the injector resistance, should be very low. The best way to test injectors is to run an ahmmeter check when running to see what the maximum current through them is. That stated it is improbable that injectors cause this as they really have got these things figured out. More likely causes of this are corroded or open spark plug wires or coils or both. Why did you change all those parts? Guess work or was something wrong with everything? Check what was stated here and then get the PCM scanned for clues as to what is ailing your car. These cars had a problem with grounds at the battery and the frame rail below the battery that caused a lot of strange problems. You need to properly diagnose before parts are replaced. Good luck.

Have you put in a lot of %26quot;octane booster%26quot; or %26quot;Fuel cleaners%26quot;?

I did that once and found out that they eat away at the injectors. Or did you purge the fuel line when you changed the fuel pump and filter?
I guess I can't get past the %26quot;2.2L DOHC%26quot;, WTF???



Check engine light on????



Was it doing this before you changed all the parts???



Checking Fuel Injectos requires a comp scanner and some special test equipment- consult a qualified repair shop.

you can measure the resistance (ohms) of each injector. disconnect each injector and use an ohm meter across the injector terminals. should be 11 to 14 ohms. this will only tell you if the injector coil is good not if they are plugged.
