I initially had problems with the starter relay and thanks to you guys I have that repaired. But now it'll crank but no start. If I cycle the glow plugs it acts like it wants to but just won't fire off. With no glow plugs it doesn't even want to at all. I had it running the other night with a lot of cranking and cycling of glow plugs. I let it run for about 15 minutes and it ran great. Next day, no start. I replaced the lift pump and checked and replaced some hoses, tried to bleed the system but not sure of the complete process. It acts like it not getting fuel. It is puffing a little smoke while cranking. It's not cold enough to even need glow plugs, it should just fire off. So…. What is the process to bleed the air from the fuel system and how can I check to see if I'm getting fuel from the tank?? I hear alot about problems with the pick up tube but since I did have it running the other night I wouldn't think that would be an issue, any random thoughts are welcome as well.</p></blockquote><p></p>
