Do you have fuel at the injectors if you dont then you will need a IP,generaly when a IP is going out it will fail to start when hot but you can pour cool water on it and it will work what you might want to do to rule out air in the the lines is get some clear fuel grade line and put between the fitlter and IP if you have bubbles then you are gettig air in the system

Does your service engine soon light come on when you turn the key on? If not, the light could be blown. Also have you checked fuses?

Check all fuel lines before engine for leaks

Check lift pump see if it's working

If it is check ffm see if your getting fuel or if it's cracked

Look in valley for fuel leaks

If no leaks crack injectors and see if fuel comes out
If no fuel comes out there is a problem from IP back.

t valve is fine . if i open my filter with the t valve open should a stream of fuel shot out? when i start to close the filter it sounds like air is coming out . second what is the right way to check the injetors for fuel do i jump the lift pump and make it run and then check ?


please keep in mind i can play with the gas and it runs for a second and has a weird idle and shuts down
