low impedence I/J, no resistor working ?!?!
hey i have a problem i have a set of 450cc low impedendce injectors, works and idles fine without resistors but with resistors it wont even crank at all.....
HELP?
im using 10 ohm 10 watt resistors..........

Don't be annoying. Posting two threads about the same thing in a few hours isn't going to make people help you any faster. Pretty sure you should be using 10 ohm 10 watt resistors.
Using a DMM what resistance do you get when testing the injector itself?

Indeed. Step 1 is to determine with an ohmmeter exactly what the resistance of the injectors is.
If you get somewhere in the 12-16 ohm range, they they are high impedance injectors. If they are in the 1-4 ohm range, they are low impedance.
For low-impedance injectors, you generally want about a 10 ohm resistor in series with each injector. The wattage is not something you need to hit exactly- it's a maximum capacity, not a precise value. 10 watts will suffice, 20 or 25 will give you a bit more headroom.

here is a resistor explanation and a calc to help you figure it out: http://injector-rehab.com/kbse/resistor.htm
it was posted in the linked thread, but figured I would put it in here as well.
