Truck started idled went to reverse it died , now it starts but it idled and died  idk anymore the codes I get are misleading because it's **** I ****** withe 

Why are the codes misleading?

Low voltage at alternator.code, my fault I blew fuse last night , but 1689 popped up on my ob2 scanner also 

1689 is from pulling fuse but truck still wont has fuel to injectors 

What about a crank sensor???

Truck cooled off started and madesign home , please tell me exactly how to test alternator , I tried a old mopar man link but didn't work

Before you spent $800+ on an ECM that may or may not fix your issue, have you checked to see what FP you lift pump is putting out?  What were your results for testing the alternator for AC voltage? 

Hawkes hey man my alternator with negative on battery and red on the alternator main, and I get .042 at idle. .050-60 at 2k rpms

New alternator same issue

That is VAC correct?  If so that is getting high, it should be lower than that.

Don't forget to test your new alternator the same for VAC.  Many new alternators come out of the box with this issue.

Well new one test .009-19 ?  now truck won't throw any codes but it seems that injection pump is what's messing up like it's being told to stop 

My harness to pump had a tan wire inside 2 wires.and a coating of wires ?

Excuse last statement the wires I just asked because I was inspecting the wires to IP
