No ground wire - Fluorescent ceiling light

I hope you can help, I have an older home with some new 3 wire and some old 2 wire. I am replacing a 15 year old fluorescent fixture in the basement ceiling with a new one. There is no ground wire on the line to the light. The old light worked just fine on that circuit. Now the new one won't. I added a junction box since the old wires were too short and used the ground wire on the NM 14-2 that started at the box and ran to the gound screw on the lamp. Is that short gound going to work or am I kidding myself? Will new fluorescent work in this situation? Thanks.

fluorescent lights often do not want to start without a ground wire.

as you have guessed if the ground wire does not run all the way back to the panel, then you actually have no ground wire. this is why it is a code violation to extend an ungrounded circuit with new wire that has a ground in it.

Sorry for the bad news. I think you know you will need to re-wire the circuit all the way back to the panel.
