My truck starts hard after sitting over night. Cold isn't really the right term becuase it's hot out now. It always took 3 cranks after sitting overnight. Lately the truck has been sitting for long periods of time and I noticed it was taking 4 cranks to get it to fire. I swapped out the rear tank (rot) and replaced the fuel filter. Now it cranks about 6 times and coughs a little may or may not run. If it doesn't fire after coughing, it fires on the 1st crank of the next attempt. Truck runs good, but is getting bad gas mileage.

I am suspect that the fuel is draining back into the tank when sitting, but I don't know how the fuel system works.

Does the fuel pump run for a set amount of time when the key is turned or does it run untill a certain pressure is hit?

Has anyone had a similar issue?

It is drivable as is, but I love this truck and would like to make it right.

Hey I have been having the exact same problem with my 97 F-250 460 HD 4x4 At first it just took a couple more cranks but now it takes a very long time to start just sitting over night. Did you ever find out what the problem was.
