2007 Silverado 1500 Starting Issues

[07Silverado]

Hello-

I’ve been having issues starting my 2007 Silverado 1500 and was hoping someone could give me an idea what the problem is. 

 

- Engine struggles to turn over for 3-5 seconds before finally turning over. 

- If I turn the key to the “On” position before starting it, wait 3-5 seconds THEN start the truck it turns over immediately. 

- I can hear the fuel pump kick on when I set the key to the “On” position. 

- Battery was replaced but the issue remains. 

- Truck will start right away if it’s been sitting for less than an hour. 

- Temperature shouldn’t be an issue (30-40 degrees in the morning).

- Here’s the kicker:  If I use the remote start it turns over no problem. 

 

Any help/input would be appreciated. Thank you.

Any engine codes like Evap slow leak or similar codes? The fuel pump check valve maybe be stuck open and letting fuel run back to the tank.  So next time you need to start it, the pump has to prime the fuel line before any gets to the injectors.  If you try to start it after you just turned the engine off and it starts immediately this would be a good clue.
