Just throw parts at it. Always buy the MOST EXPENSIVE part first
1....Best battery you can find
2....Next the starter. Most expensive one you can find
3.....Next the battery cables. Use those huge oversized "diezal buzz" ones
4.....Next buy TWO starter relays, one in case the first is still not working!!!
5.....Next, go to the hardware store and have EVERY SINGLE KEY on your ring duplicated "just in case."
