Question about 1997 Chevrolet K1500
How to see if the fuel injectors are bad on a 1997 chevy 1500 v6
If the injectors are clicking then they are worn, the only way to test is to pull out and bench test each one to see if the spray pattern is right and if they leak, you can check for shorts with an ohm meter by disconnecting the injector harness one at a time and putting the ohm meter on 2000 ohms put one test lead on the injector pin and test to ground if it goes to 0 it's shorted, test the coil buy touching the injector pins one lead on each connector on the injector you should have a reading or 4 to 6 ohms ifit's zero then it's shorted out and needs to be replaced. you can check to to see in the pentel is activating by applying power to one side of the injector and ground the other side 12 volts on most cars, if you here a click each time you touch it and remove it and touch it again it means the pentel is working, but it does not tell you if it's leaking, only looking at the tail pipe and seeing black smoke or carbon build up on the inside of the exhaust pipe will tell you if one is leaking, again to know for sure is to pull them out and bench test them one at a time.

The injectors in the 4.3 V6 vortec are the in the intake manifold, the only way to check is to have the truck scanned at Auto Zone or any auto shop that can scan for you. Most garage only charge $10.00 to $20.00 to hook up the scanner since they want you buisness and know most larger Auto Parst store scan for free.
Good luck and hope this helps.
