If I wanted to check resistance on the injector clips and the pins on the DME which setting would I put my multimeter on?

I'm at the horseshoe (omega?) symbol but there is

2000K, 200K, 20K, 2000 , 200 settings

which one should I use?

most meters have an auto-range on them, is yours digital or analog?

BTW, you can ohm out the injectors themselves, but if you are mearly looking for curcuit continuity, put your meter on the function that beeps when the 2 leads are touched, then it will beep if your continuity is good.

Ohming out wiring is tough because the longer the wire, the more resistance.

If you're just doing continuity testing, set it on the lowest resistance range. I don't think the wire length range involved in cars will have much effect on additional resistance. You should be getting no more than an ohm or so for good continuity.

Mine is a really cheap digital "cenn-tech" 7 function multimeter.

I just bought a noid light, that will do the same thing right?

I did get exactly 1 but before it got there it went to .947. Does that make sense or should I try again?

thanks!

sears has a pretty decent dvm for about $30.

If you are saying the digital meter read .9xx ohm then settled on 1 ohm thats insignificant and OK. Values that low may move around as things like surface oxidation where you place the probe can have an effect as great as the value you are testing. If you have a functional motor and know the specs for voltages at the components (or not) I prefer to check for voltage drops along the way rather than try to ohm out the leads.
