my truck will not start easily after it is off for more than 30mins. it’s will crank but not catch. on cold mornings my truck starts with no problem. it also starts right away after being off for less than 10mins. does this have to deal with the fuel delivery?
On a cold morning, turn the key to the on position and let it rest there for about 3-5 seconds, then try to start. If it starts immediately, the the fuel rail is losing pressure and that could be due to a number of things.
