20v cq, injector question

Sounds like you are not reading your meter right.
In OHMS scale, touching the test leads together will give you 0.0 ohms, not
infinity. You get infinity when the leads dont touch > infinite resistance.

Most meters have their ohm scale blown out because ppl have the switch on
OHMS when they check voltages. I suspect this is what has happened in your
case.

Use deductive reasoning. All the injectors and whatever else you measured
have incorrect readings . . .yet the car engine and accessories work.
Hmmmmmmm?

Go to radio shack and pick up several resistors . .2 ohm, 50 ohm, 100 ohm,
1000 ohm, 10k, 500k. You most likely will find a pack with a whole bunch of
resistors for couple bucks. Test your meter on these resistors and not stuff
on the car.
