2001 Cummins auto 4x4 Edge juice with att, intake, exhaust, and brand new air dog 150. Just installed the AD150 and now im having very very low psi.... like 12psi at idle start up, once i start driving were talking down to 3,2,1,and then at idle after running around 3-4. Code its throwing is the 230, 236 and 1693...the 230 is the one im worried about, transfer pump out of range??????!!!!!! Any help would be amazing guys/girls!

 

Wire the pump to a keyed fuse, not the vehicle wiring harness.

 

Would you mind explaining a little more in detail please? Also when I turn the key on the pump turns on for about 2 seconds and then shuts off?

 

Did you run a "new" 12V power supply wire to the pump?

 

The airdog 150 c ame with a new harness with a positive and negative, hooked them up to the battery..... and then hooked a plug into the old fuel harness in the engine bay and then a new connector to the pump new one.

 

did you install the draw straw far enough in the tank also run the power on wire to a fused key on wire

 

Recheck your connections

 

okay so i put the + and - from the secondary battery to the MAIN battery and it fixed it.... hmmmmm kinda weird? But now I got 16-17PSI fuel pressure stable!

 

Sounds like problem solved. Clear your codes and see what happens.

 

Now i got smoke blowing out of my air filter what the hell!!!!!!!???????
