No Electricity To #5 Injector.

No Electricity To #5 Injector.
At the injector connection what am I looking for?
1-A constant Ground?
2-A Constant Positive?
3-A pulsating Ground?
4-A Pulsating Positive?
Let’s assume it’s not the injector harness
Which wires are the ones to be checked at the ECM?
Thanks Guys

The injectors receive a constant 12v on the brown wire to them, and the other side would be an active ground (pulsating as you refer to it).
#5's active side is a blk/wht wire.

would it be the same Color at the ECM?
thanks Dude.

 

[TurboDave]

No, it changes to a tan wire at connector C111 that goes to B12 on the ECM.
