Crank no start issue

I recently got a stage 2 eoc tune. Not blaming tune just giving information. When the truck has been sitting and is cold it won’t start. I hit the brake and press the start button and you can hear fuel pump prime and all that it just won’t start unless I take the starting relay out and jump the pins and then it starts no problem. I don’t have a check engine light. If the truck is warm it will start no problem. Any help would be greatly appreciated.
