97 740 wont start

ok here is what happened. 1997 740 IL was sitting in my garage for about 3 days ( riding motor cycle) anyways i go to start 740 and engine cranked SLOW too slow. so I went to autozone got a Heavy duty battery 950 CCA because i thought maybe battery was on its way out.... that wasnt problem. ( battery was old anyways ) now it still wont start, it cranked way too slow again and now it wont even crank! battery is good!!!

so i got my meter out and had person turn ignition on ..no voltage going to starter.. im thinking 2 things 1.... maybe the chip in key ( of course no 2nd key )or 2. starter relay is shot

any help would be nice

LASERBOY:

how many miles on the car explain ur problem more

Oh ok I kinda see ur problem check ur starter,starter relay.cords,make sure nothing is burned around the starter and check all fuses.and then get back to me

there is 140,000 miles on it... I will hopefully get a chance today to look at relay.

replace main relay above drivers fender.
