how to tell if injectors are HIGH Z or LOW Z?

is there some way to test them with an ohm- or voltmeter? I got a set of injectors, but i'm not sure what they are. The seller said they were 56lb high Z's, but i'd like to verify before I install them.

Dont know about testing them offhand. You might want to check with the mfr of them, or someone who deals alot with injs like LJ.

You could always hook one up and if it burns up in 1-2 minutes you know its LowZ heeheehee err eh

Measure the resistance.... high Z are generally 12-16ohms, low Z are generally 2.5-3ohms.
