nope. The batteries tested good. still got a short crank and then it fires up n dies all in 2 seconds or less. I still wont consider taking it to a shop...not yet. But it is getting old. maybe tonight is the night

Checked all the fuses with a test light. And the ones that are only active with the key on. Simply getting light on both sides of the fuse with the probe means all good for sure? Means the circuit is good?

Take a look at this thread. It pretty much describes the issues you are having.

I guess I did leave out a key part of replacing my injectors..or maybe not, IDK, but I also did a vavle adjustment. Ive heard both that you dont need to do one and that you should do one since youre in there anyway. I followed the .012 spec and made sure the line on the balancer was perfectly lined up when 1 was TDC and when 4 was TDC and adjusted the valves accordingly. Once they were tightened, I went through a second time making sure the .012 gauge went in and had a little resistance pulling out. Could adjusting the valves cause no starting issue? Was there something else I should have done after adjusting them?

Also I turned the balancer 360 degrees( 1 time ) in between the adjustments for 1 tdc and 4 tdc
using the alternator pulley to turn

Thanks

I have my batteries getting load tested right now. Im gonna pick em up in a few hours if good and maybe try looking for a air leak on the low pressure side? from the filter back to the tank. Will it help to prime the filter housing still and spray some soapy water all over the rubber lines?

Could Fuel pressure regulator be bad and not show any codes? If I have enough rail pressure, then it has to be a leak on the low side or something electrical right?

Thanks
I would say you have a pocket of air somewhere that is not moving. Get yourself a gauge/hose assembly to connect to the fuel system Schrader valve connector on the RF to see if you are losing fuel system pressure. I installed a Kennedy Lift pump and added a Mega filter assembly about 3 months ago and bleeding ALL of the air is paramount to firing it off.

Like OkDually said you need those batteries to be fully charged.
