Starting problem
 

Hi I'm currently having a problem with my 97 5.2 I turn the key and there's no power but I got headlights & horn the radio dash lights etc don't work and turning the key does nothing at all could it be the security or something?I don't have a remote for it

The headlights and horn are on a hot circuit that will work anytime, key or not. Check all your ignition circuit fuses and the plug that goes into the interior junction box. It could even be a bad ignition switch. The old tried and true method of checking the battery is to crank it with the headlights on. If they dim, you've got a weak battery or bad connections. I take it it won't crank either? Try jumping the starter terminal itself.
