2011 1500 5.7 Hemi no start

[wniem]

I was driving my truck on the interstate about a week ago. At cruising speed (70ish) I lost all engine power but not any electrical power. Had it towed to my driveway, have been trying to figure it out. Tested battery voltage, which is fine. Replaced TIPM, did not fix anything. Tested fuel pressure right before it enters fuel rail, read 20 psi which is very low. Replaced fuel pump assembly, fuel pressure still read 20 psi. Have codes P0113, P0123, P0222, and P0562. Have a suspicion that the voltage going to the fuel pump is low, any others ideas? Also replaced IAT sensor. When I try to start, it sound like it wants to crank but will not.

I dont know if you've fixed your issue. But, you may need to make a jumper to power your fuel pump . I had same problem. yoiu can buy the fuse holders at Oreilly...hope this helps someone lol

Did you determine if there's spark?

Given your fuel pressure, There's a fuel pressure regulator back below the brake booster on the fuel line. Look up Ram Fuel Pressure Regulator on youtube. There's some good videos on it. What you described sounds a lot like that. If it turns out to be it, they're not too pricey or difficult to change.
