How do you know if an injector is bad and how can you test it


There is a tester called a Noide light. This plugs into each injector wiring socket to see if the injector is getting a pulse. You can accomplish this same thing with a Voltmeter. Sometimes the auto parts store have loaners in Noide light kits.

But this will only show you if power is going to the injector. You need to do an Ohmmeter for continuity on each injector. This will give you a fair idea if they are passing fuel.

You will be able to tell if injectors are getting their pulse using the noide light.

How do you test the injectors on a 2003 cadillac deville?


Should be able to use a noid light to check to see that it is getting the impulse to the injector. Noid lights are available at most auto stores usually in a set and stothescope place it on the injector should be able to listen to a snapping which should speed up with higher rpms!!

1999 2door blazer installed new fuel pump 60psi when tested won't start dump gas in intake starts and shuts off ??????


Sounds like your injectors aren't opening if it holds that pressure. Get a "noid light" at parts store that fits your injector harness connection (just a few bucks). Just pull connector off injector and plug in noid light. When you crank engine, the light should blink rapidly. Try all of them, or at least one on each bank (side).
If light doesn't blink, then check your injector electrical circuit. Power to them is fed through your ignition switch, and the ecm grounds that particular injector at proper time to make injector work.

2002 hyundai santa fe 2.7 multi misfire number 2and 5 cylinders


OK IS THERE IS ACTUALLY A mis-FIRE THIS VEHICLE SHOULD BE SHAKING DURING IDLE AND ACCELERATION IF IT IS, here is what you do get a noid light this used to check injector pulse. This vehicle will set a misfire code if injector is not functioning efficiently or bad. A noid light is like a test light bulb can be bought at almost any auto store.SART UP VEHICLE AND DISCONNECT THE INJECTOR WIRE TO THE CYLINDER THAT'S mis-FIRING AND CONNECT noid LIKE TO ELECTRICAL PLUG. DO THIS ONE CYLINDER AT A TIME. The nod light should have a steady flickering light/consistent pattern of flickering. If there is Gap/irratic flickering or no flickering BINGO you have found your problem. NO FLICKERING= bad/broken injector wire if not broken BAD COMPUTER/ECU. IF THE FLICKERING IS CONSISTENT /GOOD = BAD INJECTOR..replace injector and solve the misfire problem. However is all the components tested are ALL GOOD. Then the only other SOURCE for a mis-fire is the camshaft sensor that provides reference for injector pulse and the crankshaft sensor provide reference for Spark pulse. JUST ON A LAST NOTE: make sure all oils are getting electrical power to them. Good Luck I know this is alot of info at once. Contact me if you need more help. Thanks fr using FIX YA
