I have a 2006 Ram w/ the 5.7. Crank no start and no 12 volts at the injector with the key in the on position. The wiring under the hood is different than my 2005 hemi Ram. I have 50 psi at the fuel rail and will run briefly with some starting fluid. This does not have ASD relay like previous ones. The fuse block is totally different. I even bought a Haynes manual but did not cover the 2006 wiring. Is there something preventing the 12 volts at the injector. I'm starting to lean toward the PCM. Hopefully someone can relate.
Thanks.

I believe so since it would run on starting fluid. I haven't verified it thru my ground tester.

Did you Check Fuse 64 to see if it might be blown? PCM/Injector 25A
