Dealer told me lift pump was bad. Replaced lift pump. Still the tank will not pressurize. Installed a new delphi pump. Key turned on no noise/squealing sound or nothing coming from tank. Per dealer , i am getting power to harness to lift pump. Is there a relay/fuse? Something im missing?

I had something similar happen a little over a year ago. I literally told them "I have no power to the pump, I can't hear it" - they tried to sell me $15,000 dollars in an entire new fuel system. My warranty wouldn't cover it either because they claimed "contamination" - I allowed them to change my lift pump, HPFP, the filter housing/heater, and even the TIPM unit under the hood - mostly for my own peace of mind. They also bilked me for a new battery north of 5-hundo. Long story short, the day I went to pick it up, it did the exact same thing I brought it in for, so they got $5800 from me, and I filed a complaint with FCA that went unanswered.
My rig sat in my driveway for 13 months after that languishing away, making payments, keeping insurance up on it ... I was pretty pissed.
Turns out the problem the entire time for my rig was the wire from the TIPM to the fuel pump itself - the one that runs down the driver's side frame-rail. There was a break in it somewhere. My neighbor who has worked on heavy equipment for nearly 40 years, ended my 13 month downtime in literally 35 minutes with $7-dollars worth of wire. It's been a while since I had the repair done, but I think he said it was a pink wire that ran down the entire frame. I'll have to look. We replaced it with a fresh 18-gauge wire and I've put on about 2500 miles on it since with zero issues.
Maybe you'll get lucky with a similar poking around with a power-probe like I did.
