:CRY: Well, yall have been a big help on other issues, so, here is a new problem i am having. I am going to try to make a long story short here! I have 5 different dodge duallies. I say that to better explain my issue. The 06' that I was having problems with is now running great it was the injectors, but to figure that out for sure, before making that big purchase, I pulled the injectors out of my 05' that was running (with the exception of loss of power when loaded). When its' injectors fixed the 06', I just went ahead and ordered injectors for the 05'. I got those installed tonight, and it will not start. I retraced my steps and cannot find anything wrong! The injectors I installed were OEM Bosch injectors, I did not replace the tubes.(But I did check and clean them). I am wondering if whatever was causing the loss of power problem coincidentally went out.
I am pretty sure that the loss of power problem was or is the lift pump, because it regains power when fuel guage gets below 1/2 tank. I can hear the lift pump run, but I do not have a fuel pressure guage to check pressure.
Please HELP!!!!!!!!!!!!

ok, I checked all of the supply lines, the injector tubes, all of the injectors, just to make sure that i did not make a careless error. Everything looks great! I also checked the lift pump to ensure that it is pumping, when i pulled the injectors to check everything, they had diesel on them.So I know that they are getting fuel. Is there an easy way to check the FCA and would it cause it not to start. I shot a ittle stating fluid in it to see if it would help, it ran for about 3 seconds and died( pretty much when it burned all of the ether up)

i put the wiring exactly like it was on the old injectors. i double checked to make sure i had it right. I have also checked the 3 harness plugs, they are all in good. do you know of a way to check and see if they are firing?

ok, I just pulled the valve cover off again. i am probably going to wear the bolts out! LOL I checked the voltage with a test light to all of the injectors. They all have some voltage. Number 1 and number 5 have more voltage on one leg than the rest. I am going to test them with an actual volt meter to see what the voltage is. Am I headed in the right direction, or am I headed in the wrong direction?

I pulled the harness on the fca. Truck still did not start. I am feeling my way through this, so what exactly does the fca do, and why would it start with it not hooked up?

I installed all of the injectors, then i installed all of the supply tubes, then tightened injectors, after that, I torqued all of the keepers to the supply tubes.

Got it!!

:thumbsup:hyper: alright!!!! I finally got a chance to work on the truck again. I was getting ready to do another injector swap last night, thinking maybe I just got bad ones. And when I went to remove the number 1 supply tube, i noticed that it was not seated good. I re togeteorqued it, put it all back together, did some serious praying! Aalnd it fired right up.
Bad news is it has no power at all, apparently what ever was causing it to lose power with a load, has got worse.
maybe lift pump?
Thanks again for all yalls help,
Brent
