Injector pulsing/firing

[law]

How do I go about checking for injector pulsing? And what do I need?

 

[HISSIN50]

a noid light. It is under 5 bucks at the parts store.

WIth the key on, you should have constant 12 volts to each injector. Then the computer pulses the ground to each one (ground is easier for the computer to modulate - since injector pulsewidth adapts to reach stoich).

Good luck.

Thanks for the help!

Is there another name for a noid light. I cannot find it on a search at autozone.

Noid light is the only name I know. They should be in the tool aisle in the store. I would just call and see if they have one.

Good luck.
