Starter

first dis connect the neg. batt. cable , you may need a memory saver , I've heard on a 9 volt batt. hooked to the lighter for this , then you get underneath and hopefully there's nothing in the way of a couple of bolts holding it in , there should be small nuts above the big red wire for the solenoid wires , clean all electric contacts and make sure no wires are touching , the starter probably isn't cheap but buy a quality one , they usually don't have them in stock , they "guarantee " them but you still have to do the swap , see if there's a delco oem dealer near by

make sure it's not a relay or something before you replace it
