Default '94 5.9 Cummins won't start unless I depress throttle

I have a '94 5.9 cummins that has just started to not start unless I depress the throttle.
I am running a cold air intake and 4" open exhaust.
other than that no real motor upgrades.
The motor has approx 300k and once started it runs very good

I am afraid this will lead to something bigger

thanx for your help

I should have maybe given more details that i just remembered:
when i say it wont start, i should have said it wont stay running.
it will start (fire) but only for a second or less...... then shuts off.
once it is running it does idle and run as it should

are you thinking i dont have the idle set high enough?
