hmmm, got the same problem on my buddies 06 as well, still pulling out our hair

 

basically u have to get the whole injector. i think u can take it to a dodge dealer or a cummins dealer and they can use a computer to see if ur injectors are for shure not good. im getting all mine replaced with new injectors but let me warn u they are salty. i was told if ur getting one u might as well replace them all

---AutoMerged DoublePost---

i capped my fuel rail too hoping the truck would start but nothing. i would take it to someone who can look at the injectors from a computer or take them out n have them sent to someone who can test them manually

 

ok I guess I'm gonna replace all my injectors. has anyone ever had there injectors rebuilt

 

did u get them tested. u should before puttin out all that money just to make sure

 

seen 03 due same thing and replaced all parts like you did, it was a cracked fuel line.

 

was the fuel leaking out, or sucking air. which line was it. just wondering

 

There was a tbs out on the fuel line on the 03 about cracking. Have you rechecked your fuel filter?

 

any updates

 

we didn't notice any fuel leaking out just couldn't get it started on its own had to use starting fluid. to get it to run but when running it ran fine just wouldn't start on it own. and it turn out to be cracked fuel line.

 

You might check your crankshaft sensor?
