Truck won't start after sitting for longer than a day
Original Post: 2003 Chevrolet S10 V6
2003 S10 V6. If the truck is started everyday it starts right up with no problems. If left sitting for at least 24 hours it is hard to start it. It cranks up and tries to start but never actually starts. To be able to get it to start the truck has to be primed with the key and then put the gas pedal to the floor while cranking. I have recently replaced the fuel filter, air filter, and fuel pressure regulator in attempt to fix this problem. When the truck is turned off the fuel pressure reads strong but when running fuel pressure begins to drop off. Any ideas on what is wrong?
Is this a good question?

Hi,
I'm wondering if you have a fuel pump problem. Here is a link that may or may not help. https://www.youtube.com/watch?v=piOzN1tZ...

I don't think it is the fuel pump because I can hear it when I cycle the key and the truck does start just not after it sits for over 24 hours. I also noticed this morning that the truck is idling low and makes a weird growling noise when in first and second gear to keep the rpm up. That issue started after replacing the fuel pressure regulator.

Hi,
Wondering if you can get hold of a scan tool and connect to the OBD2 port.
You might get an indication of what's happening. This may help if you can.

Ok I will go get that done today. The growling noise started after replacing the fuel pressure regulator. I at first thought it was my clutch going out but now don't think that is the problem. I also did get a check engine light test done when the growling noise started and it was telling me that I was getting a lean mixture which was causing low RPMs.
