I got a 98 Volvo V70 xc awd turbo I had for not to long and it stopped starting no crank I can jump the starter relay fuse and get it to crank and start it will run just fine no problems except for sometimes rpms will drop randomly I've replaced the replay the ignition switch ignition coil n some other things but it doesn't help the man dome lights on the roof don't turn on when doors open but the ones in the foot well do but all the dome lights work fine if I turn them on myself that problem started after the starting problem happened and radio only seems to work when it has a fully charged battery otherwise it won't even turn on when key is on but radio works till it was to loud then It turned off again but I can't figure it out but I drive it daily but I just start it with a wire any ideas???
