I am having a problem with my truck not starting. It acts as if the battery is dead, doesn't crank over and then there is barely any power. Totally acts as if the battery is dead. Then after letting it sit a minute or so the power comes back and the security system is on and the lights are blinking. I reset the security system with the key on the passenger door and retry and it does it over and over again and then finally starts. I had it happen last saturday and then again this past saturday morning. last week i only had to do the security alarm deal once and then was able to start it but had to do it about 5 times and then was finally able to start it. Any ideas? Is it a bad relay or something???

 

Check and clean your battery terminals
