The truck starts and some time it don't

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! Intermittent starting issues can be a real headache, especially when the problem likes to play hide-and-seek! Since the fuel pump has been cleared and the filter and sensor are new, let's turn our attention to some other common troublemakers. The ignition switch, starter relay, or even the battery connections could be the culprit. Sometimes a weak battery or loose cables can cause the truck to start only when it feels like it, especially in cooler early morning hours. Another thing to consider is the crankshaft position sensor, which can cause no-start conditions if it’s failing intermittently. It might be worth testing or swapping it out. I’d also suggest checking for any trouble codes, even if the check engine light isn’t on, as they can give a clue about what's happening under the hood. Keep at it, and I hope this narrows things down for you!
