i went to start my 99 rk the other day, and when i hit the starter, it turned over for a second and quit. now when i turn the switch on start, it does nothing- like the battery is unhooked. but when i turn the switch to the acc position, the dash light comes on like normal. i have checked the fuses, tightened the battery posts, even changed out the ignition switch, and still nothing, someone said it may be a starter relay, but i don't know which one out of the 4 is the one i need to check. if anybody has any ideas, i would appreciate them.
