Hey guys I had a hole in the timing chain cover and got that fixed. Now the truck will start and idle rough then die.The fuel pressure is low and have Replaced the fuel pump but that did not help anybody have any other ideas. Thanks

 

I'm having the same issue. My next step is going to be dropping the tank and clearing the fuel lines. Good luck.

 

If it ran well before you fixed the timing cover, it must be something that happened while you did that. I'm sure you looked for vacuum line problems but check for cracks that can't be seen by wiggling them or pinching them one at a time with needle nose pliers. Also, look closely at the intake hose at the throttle body. They can crack underneath or just be loose enough to leak. Good hunting.
