bad injectors? need confirmation.
First thanks in advance for the help. I have an '06 3500 stock with 315000 on it. Its been a great truck. so far I have changed the CP3, FCA, dump valve and the # 3 injector. all about a year ago when I hit around 300k. The recent issue is when it sits overnight or a couple days it wont start unless I unplug the FCA. I am pretty sure that its time to bite the bullet and get the other 5 injectors. Am I on the right track or is it possibly my lift pump too. Mine is an '06 so its in the tank. BTW just put 35 gallons of fuel in it before this issue started (sucks)! Guessing injectors, but should I change the pump too with that many miles on it?

Probably injectors with that many miles. Of course, you need to verify LP pressures but if it runs fine once it is started not going to be the LP. You need a set of injectors, preferably something better than stock if so inclined by at a minimum new Bosch production injectors. Not sure what the single replacement was but unless it was NEW don't bother piece meal on injectors.
You can find some good deals on line, DAP, Engineered Diesel, for stock production units, or, Exergy or BBI for some better quality units. Do some research before buying.

Yes, at this point new feed tubes is a really good idea. If you stay with OE injectors chances are you really only need 5, if it was a certified NEW injector and not a reman.
Be careful with the advertised 60 HP injectors, some flaky results from them. The BMS50 is really the only production run injector that seems to have little problems and they are not perfect either. The ones marketed as BMS50 or 60 with the 124 pattern are not a production run injector so all the tolerances are solely on assembler and that is where the variances can vary widely.

Factory filter on an 06 was 10 um, the newer Fleetguard filter is 7 um, a Donaldson that fits the OE housing is 5 um. A Donaldson or CAT at 3 um between the OE filter housing and the CP-3 is about the best way to do it easily.
