injector block off via cap vrs electronically

[sandmanxx]

Question on isolating bad and /or possible bad injector using:

hard line cap (no fuel to injector) and electronically via scanner or injector wiring.

Question is if isolating via wiring (two wires to injector solenoid ) and still having fuel sent/stuffed down injector tube (by not capping of the hard line) would this flood the cylinder
with fuel and cause problems if you outback somewhere and trying to get to town. I mean if you "know" the cylinder in question is the issue and where trying to get out of the middle of nowhere. Are does the solenoid not firing keep fuel from cylinder??

The only sure way is the cap,injectors can drip fuel with out being fired.My Baja trips always had at least one cap along for the ride
