Last two days tuff starting and VERY RUFF IDLE for about 3-5 seconds then everything is OK. Any educated ideas? No CEL/MIL.

Air in Fuel?

Clogged Fuel Filter?

Bad Glow Plug? (with no CEL)

In the morning check for a soft plunger on the primer pump I'll bet it's soft. Since there's no mention of a lift pump in your sig that would be the first thing to check. And it's easy to check too

I'm experiencing the same issue. Was this the solution? If so, how do I check?

Before you start the vehicle push the primer pump handle. If it does not have resistance, then you have air in the lines. It is located under the hood by the firewall on the drivers side. The fuel filter will be sticking out under it. It is black plastic and has a spring loaded plunger towards the passenger side. The plunger is the primer pump. That is what you push.

Forgot about this post. I bled the system and all is well...

Is it time for the lift pump mod?
Gmctd is a great source of inspiration and information.
Is the old hound in love and out of touch?

I thought my primer was firm...until I added the mopar/cummins pump. Now, it feels like the consistency of a racquetball, very firm. I never realized that for 2 years, no matter how many times I pumped, I never bled it completely. I don't know if the stock head is even capable of getting all the air out on its own.
