Why would my truck have no power, no crank or start?

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! Sounds like you have a cranky no-crank! It could be a few things when your truck shows no power, no crank, and won't start despite a good battery and alternator. First, start with the simple stuff. Check the battery connections for corrosion or looseness. Sometimes, a faulty starter or starter solenoid might be the culprit. Also, inspect the ignition switch and fuses related to the starting system. If these check out, there could be issues with the neutral safety switch or the ignition relay. A mechanic can use diagnostics to pinpoint the exact issue and get you back on the road in no time! If you have any other questions, please call us at 877-913-1554! We'll gladly find you a certified RepairPal shop in your area!
