2002 7.3 another hard start problem.
I have a 2002 F550 4wd 7.3. I know there are so many of these hard start problems on this forum. I know i have read a lot of them. If my truck sits for 2 days it won't start. It cranks but won't start. I have changed the GPR also the other relay heater intake relay. Then i had the glow plugs and valve cover gaskets replaced. This is where is gets so frustrating. If i plug the block heater in it does not matter how long the truck sits it fires right up and runs great. Any suggestions would be appreciated.
