Still intermittent no start

[speedshift]

My 81 spider has always started first turn of key for the six months i have owned it. then it happened. I finished complete body prep ( at least 40 hrs) for repaint. No start! No nothing! No starter click Googled Thads Fiat Pages. downloaded FIAT FUEL INJECTION DIAGNOSTIC MANUAL ONLINE . This is a very comprehensive do not let it intimidate you. BUT after I tested inline fuse under dash ok, fuel pump ok, double relay ok still no start. I jiggled key in switch, no start, giggled key again START! Is ignition switch bad? Re started fine then suddenly stopped again? Guess what I found. follow the wires from the ignition switch a few inches to the white connector. clean this connector reconnect and MAMA MIA ! car starta good now! How many times have i read about CLEAN ELECTRICAL CONNECTIONS RULE!!

Hi speedshift. i had same problem tracked it down to box that is in right hand footwell on side of inner wing. would just click on turn of key but light tap of box would fire straight up. sticker say,s it is something to do with seatbelt warning. Has anybody else had this problem?
