Baffled

[spookchucker]

Hopefully you guys can help I have a 2005 hpdi 300.
I was fishing tournament on Lake Mead everything ran fine all day 2.
The third day idiling around to pic up my AAA it quit running and I couldn't get it started.
Since I have came back the things I've done again that I did prior to leaving. I changed out the water fuel separator , bulb I also change the fuel line from the ball to the water fuel separator. Prior to leaving I also replaced the diaphragm pumps, plugs and all filters.
My issue is that i cant keep it runing for more than a few seconds.
I found one the clip from the throttle to the throttle sensor broken that I fixed. When i start the engine it seems that keeps running out of gas.
I can go back to the ball then try to prime it and see if I can feather it no change.
As soon as I hit the throttle it bogs down anyone have any clue.

learn to create sentences.

You really need to hook it up to a computer and look at what is going on.

sounds like a fuel problem so high pressure fuel reading along with low pressure should lead you to where problem is located.
VST is either running out of fuel or the HP pump screens are plugged up .
All the filters and screens need to be cleaned /replaced

Sry was talking into and didn't proof read first.
I didn't think it was a essay I just was looking for help.
Thank you for the information you so kindly was willing to share.

you said replaced filters.
did you get them all?
did you pull and clean the VST and replace the filter/screen in there?
what about the prefilter to the vst?

[spookchucker]

I did all filters including water separator.
I did not do the vst for this reason.
I replaced the 2 diaphragm pumps because at idel it seem to run out of gas some times it would and be hard to start.
I want to see if it fixed that problem before I did vst so I would know what fixed it.
I'm going to order a new pump and vst filter but not till I do a pressure test on the fuel.
I just need to find out what it should be first lol.
I also had thought since this is the first time I have ever ran the tank so low I might have a clogged filter.
