ok as ive been posting i have recently replaced ignition lock cylinder and now it wont start. after finish installing it fired right up. go back to start it an hour later an nothing. the lights wouldnt turn on or wouldnt crank. i figured i had probably left somthing on and the battery just died. jumped it fired up imidiatley. let run for about 20min. turned it off and nothing. wouldnt crank and lights wouldn't turn on. had battery tested at napa and said was good. reading about 13.5 volts. put new connectors on and still nothing. never had this problem before anyone have suggestions. thanks.

p.s. while running volt meter on dash reading 14. as soon as i shut it off and turn the key over wont even move the gauge.

 

sure ignition not staying on

 

i thought that but after i turn it off the radio or no lights are still on its been running for about an hour. and turned it off and it started just fine. the volt meter was reading about 14 so hopefully it was just low on charge.. i suppose will see in a few hours. it dont help its 5 degrees.
