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?
