Check battery first........connectiions at battery and under vehicle at starter......You need a testlight
to check for power at starter when you try to start it....(2 man operation).....If you dont have power at starter when turning switch more than likely switch or relay is bad....More than likely have a faulty starter / battery / or bad connection

this could be a starter or the enigtion swicth yes if you crank the key to long it will kill the battery.

there located on top of engine under the cover thats says V8 FOUR CAM 32, 4 S.P. on each side,remove both covers and its easy access after that.

check the computer known for going bad. auto computer exchange in Davie fL can fix it

Check your alternator

It cranks but won't fire? Possible Fuel pump. Do you have access to a fuel pressure gauge?
