Fuses are good, battery's are brand new, New glow plugs, starter relay, glow plug relay, camshaft position sensor, I have 50psi fuel pressure, wait to start light comes on, rpm gage moves when I crank. And a little bit of white smoke puffs out the tail pipe, it will start and run for a sec with startin fluid so I know I have power to glow plugs.... I think it's the IDM or ecu , I have a ts6 position chip on it, "removed at the moment" please helppp!!!!

 

I would look at the ICP/IPR wiring to see if you knocked something loose there or if you have in your ICP connector. That's less invasive then starting to check wiring and voltages at the UVCH connectors. Here is a link below to a good troubleshooting document.

Just because it runs on either (which you should not do), doesn't necessarily mean you have power to the glow plugs. They will run on either without the glow plugs. Check for voltage drop across the GPR.

 

^^^^^ +1; the ether actually indicates the opposite; most likely the GPs are NOT working. If the GPs were working, they would very likely have ignited the ether and blown out the intake. There's a whole set of tests you need to do of the GP system; plenty of threads on the subject.

But rather than reading about the parts you threw at it, tell us about why? Did they all test bad? Do the replacements test good? Also, under what circumstances did it fail to start? Did it stall while underway, or did it just fail to start one morning? What might have happened leading up to it?

Edit - just realized you have another open thread on this (keeping one thread makes it much easier to follow, BTW). So in that OP, you say it stopped producing white smoke. But now there IS some smoke? That's a clue. The important thing is, of all the things you changed, at which point did it start producing smoke?

 

Yes, one thread on one subject makes it a lot easier to keep up with what's going on.

 

Check the stickies for "no start flow chart". In fact, check the stickies for everything regarding your truck. It's all in there.
