I just rebuilt my 2003 dodge cummins. It won't start has upgrade lift pump in tank. The relay for lift pump clicks constantly bully dawg can't read dtcs and self test won't pull codes fuel gauge shows it's on empty and volt gauge wont work. Also sensor on injection pump clicks and injector solenoids click on and off. This issue has me stumped has anyone ever experienced this before? Also engine doesnt turn over fast enough it has good battery's on it.
