Testing injection pulse

[ozfreerider1]

Hey, Can anyone tell me how to check the injection pulse, thanx

[The1]

Hook a scantool up and check the delay? pulse time in ms.

k from where to wear

[The1]

sorry mate your not making sense

[ozfreerider1]

so I guess you cant check with a multi meter, Do you need a special meter ??,

[Brett_jjj]

As The1 said,you need a proper automotive scantool, (Tech 1 etc), that plugs into the diagnostic connector.(ALDL connector).See holden or an auto electrician, they will have the proper scantool to do this.

Na mate,I wouldnt say your an idiot.You cant be expected to know these things until someone tells you or whatever.

you can check it with a noid light

[cander24]

Yeah as mentioned, the injector pulse is far too quick to measure on a multimetre. Other than a scantool, you can also use a 'noid lite'. Think of this as a light globe you plug into an injector harness clip while the motor is running and you'll get a flash of the light each time it pulses.

you can get a noid light
you just unplug your injector and put the noid light in the injector plug, you will see it flash if there is injector pulse
they are only cheap
a normal test light or multimeter wont read the pulse fast enough

heres a link to a couple on ebay

You can't use a multimeter on hertz can you?
wouldn't that give you pulses per second

[Brett_jjj]

Ah,forgot all about a noid light.Thats probably the cheapest and easiest way.
