Lately I've experience starter issues with my 2003 GX 470. When I insert the key and turn it, all dash lights come on but it doesn't start. No sound, just nothing. If I try again and again it eventually the starter engages and will turn over and start. Sometimes this takes just a few tries and sometimes 20-30 tries. It doesn't happen all the time, just when I least expect it. Any ideas on where the problem may be?
