Help with hard starting issue when warm outside

[Juice75]

So for the last two years, my truck takes three cranks to start if the temp is warm outside. It almost acts like it isn't getting gas. Once it has started, it will start on the first try, unless it has sat for about an hour. Then it takes three again.

I've done all the regular stuff like plugs, wires, pcv, airfilter, fuel filter, etc.

Any ideas on what might be causing it? The weather is warming up, and this is starting to drive me nuts already.

yes sir, my truck did same thing for years. inside the fuel pump there is a check valve that holds pressure in the fuel lines after the pump is turned off. if the valve goes bad(which mine did and sounds like yours did), once the key(fuel pump also) is turned off the open valve allows all the fuel in the lines to gravity feed back down into the tank. to test this theory, get in your truck, turn it to the on position but do not crank it. do that once or twice, then fire the truck up. the turn or 2 of the key prime the fuel lines again and itll fire up. unfortunately you have to replace the pump to fix this issue. but if the valve is bad, id personally expect the pump to go anytime

Thanks for the info. I'll give the key test a try today. Isn't the fuel pump inside the tank? How do you replace that? Or is that something you just have to suck up and pay someone else to do?

u can do it yourself in a few hours. run the truck super low on gas before the job, that way you wont slosh a half a tank of gas on yourself. theres multiple how to videos on youtube

May I also suggest an oem fuel pump. If you go cheap, there's a chance you will be replacing the pump again real soon.
