Engine/Transmission (1998.5 - 2002) Ran great the last time it started!

I have a 2001 Ram 2500 CDT and unfortunately live in the heart of the rust belt here in Pennsylvania. The truck developed a fuel leak (due to rusting away) from the line that comes from the bottom of the fuel filter to the low pressure side of the VP44 pump. I replaced the line with a few fittings that I purchased from Vulcan that eliminated the banjo bolts and converted it a 1/2" ID rubber fuel hose. I bled the fuel system first at the VP44 low pressure side and then at the injector side. The truck started up after a few cranks and ran great during my 15 minute test drive. Parked the truck for about 20 minutes and now it won't start. It cranks and I can hear the pump running after I crank it. Checked the truck for codes and I have two, 1693 (Companion Code) and 0230. I understand this has to do with voltage out of range on the lift pump, but what does that exactly mean. I went through the VP44 testing docs from Blue Chip and found that with the key in the run position I am getting 12. 84 volts on PIN 7 of the connector for the VP44 pump. When I attempt to start the truck, the voltage drops to about 9. 02 volts. Is that too low? I hope this doesn't have to do with the VP44 pump! It is only 2 to 3 years old and has less than 25,000 miles. I can only assume the truck got wind that I am trading it in for something more reliable (and less rusty) and this is its final FU. Any help is greatly appreciated.

The 0230 is usually the lift pump has failed but could also be ECM or wiring

If you have replaced all of the lines and fittings, you might check for an air leak on the suction side between the LP and tank. this happened to me and also the LP could be bad even if it can be heard running, this also happened to me, What is your fuel pressure??
