fuel injectors

[john ardito]

I have a 1994 Q45 Inifinti. I get no ohm reading on number 5 injector. I have read on your site a high reading means a bad injector, but nothing when you get no reading. Does this mean it could be a electrical problem not the injector?Thanks John

"No ohms" are you saying very high resistance or zero.

An open circuit is either in harness, connectors, or injector.

If you're measuring directly on the injector top it means you have a dead injector. If you're measuring at the connector you have either a dead injector or a bad injector harness. Do you have injector symptoms- rough idle? What's the reading on the other fuel injectors? 10.0-14.0?
