Hey y’all, my trucks giving me problems. In the morning no matter the temperature when I get in to start the truck I’ll crank it over for about half a second and it’ll crank and run for about 5 seconds. After that it dies and I have to crank it again but this time I have to crank on it for 7-8 seconds 1 or 2 times before it cranks. After that I can drive it and kill it and it start up perfectly fine and stays running. Any ideas? Glow plugs? Injectors? Pump?
