When I start my truck it turns over until I stop and try again and then it starts and in the morning it will start first try?

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! Sounds like your Silverado’s got a case of morning charm but mid-day stubbornness. If it cranks fine but doesn’t fire right away, the issue might be fuel-related. A weak fuel pump, clogged fuel filter, or a faulty fuel pressure regulator can cause hard starting after the system sits idle for a bit. Another culprit could be a crankshaft position sensor or ignition module that’s temperamental when warm. Sensors sometimes fail intermittently, causing inconsistent starts. To narrow it down, check the fuel pressure with a gauge (especially after the first failed start) and inspect the ignition system for weak spark. Also, listen for the fuel pump priming when you first turn the key.
