Check that the vacuum hose from the intake manifold to brake booster is hooked up. Might try replacing the cam sensor, lastly, crank sensor, it's behind the starter. Sorry, that's all I can think of.

 

Did you ever figure out why it wouldn’t start ?

 

 

I have some problems hits but want start

 

 

Head gaskets are a one use only thing. If it is pulled back apart a new gasket goes in, as well as new head bolts.

 

Timing is off. The VVT engines are tricky to time. The timing marks dont make sense.

 

Sorry for the long post, but I'm at wits end with this. Nearly 2 weeks without my truck and the last week just trying to get it to run.

To start, I had a bad lifter tick with a #6 misfire code. Had a locked up lifter roller which took out the cam lobe, so I put new ones in, new camshaft and 16 lifters. Got it all put back together, and started putting coolant in when I saw it was starting to come back out at the front of the block. I swapped the head gaskets left to right. Apparently right is as you are sitting in the truck, not standing in front-always got that backwards. I cranked it up for maybe 20 seconds to listen, and everything seemed ok. Tore it back apart, swapped gaskets around (THINK it should be ok?? open to opinions), and put it back together again.
This time, it won't start up. If I let it sit, it will try to start up right away, then fizzle out, then hit a little towards the end of the start cycle (didn't know the starter would keep turning for a few seconds till this experience). After reading a little on the internet, I tried to start it with WOT and it did start. I can keep it running if I keep the RPM around 2000 or above, and it starts out rough and gets a little better, but if I let it try to idle it stumbles and dies. I pulled out random spark plugs and they are black and wet with gas, and when I started the job they looked normal-about 15-20k miles on these. No check engine light except multiple misfires.
I read some more and thought it might be leaking injectors, so I pulled the passenger fuel rail, cycled the key 2-3 times and no fuel leaking. That's the way I understand to check for that, may be wrong. I pulled connectors off random coil packs to see if I could find a missing cylinder, and found nothing. I don't really know how to check the crank or cam sensors, but I pulled the connector off the cam sensor and I got a code and it wouldn't even hit once.
I keep thinking I screwed up when I didn't get a new head gasket and maybe should go back to there, but it doesn't really seem to fit with the symptoms. Any ideas would be greatly appreciated.

Did you ever get this figured out. I am having the same problem with my 2013 ram. Just installed a 6.4 cam and now it will not start. All the same symptoms you had. Any help would be appreciated.

 

Its timing.

make sure the cam phaser is right.

 

All timing marks are lined up plus top dead center on one. Is there something special about the cam phaser I don't know about?

 

I had the same issue where it wouldnt start after changing the lifters, cam, and head gasket. It ended up being a pushrod that was slightly bent.

 

I am currently having this problem with a 2013 Ram 5.7 Hemi with a mopar Non-MDS cam and lifters. Did anyone figure it out?

Found this last night, pretty much describes what I have going on so I’m going to look in to it. Hope this helps some one!

Check the push rod make sure there are in the right place there a second hole for oil to go throw that the rods can go throw

Did you get it fixed ? What was it ?

 

Ik this is late but this might help anyone who might have this issue. Check the pushrods. When you install new lifters, MDS or not, you have to make sure the push rods are seated into the slot correctly. It will make a click noise and push a little more in. Make sure the rocker arms line up and nothings bent or damaged.
