Yeah I'm going to give it some more tomorrow in hopes I did give it enough time to clear out the air, with the way this truck has been thus far I'm nervous about not replacing the VP44 when I already had it removed but that will be for another day. I've dumped enough $$ into this rig already time for it to run hopefully!

If the VP is not giving you trouble l would not have replaced it.

If you have the relay wired with the ECM triggering it then you can get the fuel pump to run without bumping the ignition/starter.   You can remove the relay and put a jumper wire between terminals 30 and 87 in the plug;  as long as that jumper wire is there the fuel pump will run.

Thanks @IBMobile you have been a tremendous help today along with everyone else!! Random question, will fuel make it up to the fuel rail without the truck turning over? If I just have the pump running like you just described should I see fuel at the rail with the lines cracked open?

[IBMobile]

Yes, I've done it to bleed the system when MoparMan and I replaced the injection pump, when I've replaced fuel filters, and when replacing injectors.

Got the truck running this morning after letting the pump run some more. As I was doing a leak check I noticed two different areas are leaking oil. 
 

first is right next to the VP44 where I grounded the wires for the W-T mod. I used a red lead to show, it’s bubbling out of the grey RTV looking area. Should I just reseal this area or do you think it calls for removing the front half of the cover and replacing gaskets? ?

 

next leak is coming from the OEM fuel pump location where I installed the delete plate, it has a gasket on it but it’s definitely leaking from that spot maybe some RTV?

[dripley]

You could try cleaning up the first spot and sealing it. It might work. If not its not a tough job to pull the just time consuming. Did mine a while back. You will need a new front main seal while in there.  Rtv would work fine on the delete plate.

Thanks @IBMobile installed my lift pump relay today. 15 amp pump fuse and 2 amp ECM fuse. Thank you sir!

Looks like a clean setup, where did you get that relay from? I've been searching around town and cannot find anything with a resistor incorporated (online is next obviously).

 

Also do you mind providing me with how you have everything wired up for the FASS pump, I see you mentioned a in line fuse going to the ECM etc. I have not seen that before.

 

Cheers!

I just followed @IBMobile guide. He linked it on your thread. He even gives the NAPA part number relay that has the diode. It’s on the first page. I bought two. For a backup.

Wire your relay like this.

Thanks, guess I just blasted through that article to fast during the day! I'll have to look back over it.

They make those relays with a mounting tab so you can screw it down. May be harder to locate
