let me first start by saying I just recently purchased a 1 owner 97 cummins with 250k for $3000 the truck is in excellent shape with a new turbo new tires and new trans. i feel kinda bad as the dealer told him it needed a new injection pump which would run him over $2500. any way i cleaned the fuel filter and screen and now she runs great lucky me!

so on to my question on startup i have to bump the throttle to get it to start hot or cold after that it starts up fine. it's been in the 20's these last couple mornings so i have had to feather the throttle to keep her going for the first few seconds but after it evens out it runs great. is this normal to have to bump the throttle at start.

thanks

man mines ran like that since Ive had it .Ive put on over 100,000 miles like that.It always needs a bump when its been sitting.Yours probably could use the idle turned up a bit

 

check the idle, you should never have to hold the throttle on these 6bt's

 

even when ice cold no block heater?

 

check the timing. and or idle adjustment

 

hi
mine always likes a very light touch on morning fire up also , idels fine after a few seconds ?????

 

idle needs a bump or maybe if its got a 3k gov spring it might be a tad tight just my .02

 

yep, of course its gonna white smoke for a little but thats it.

 

Mine LIKES a bump, it will start without it in the cold.
I personally would rather have it fire immediately, so I just feather the throttle.

 

yeah mine will start faster with a bump but its not needed and i just hate all the smoke it gives off at statup when i do that.

 

What RPM does the truck idle at?

My dually used to idle around 450 or so, it didn't like to start without me resting my foot on the throttle. I bumped the idle up to about 950 in park now, in drive its about 600 or so. I don't have to rest my foot on the throttle any more when starting either.

 

Mine starts great without any throttle unless it's very cold out and it wasn't plugged in; then it tends to stall without a bit of throttle. After warming up my idle rpm's show around 800rpm when in drive.

 

Mine will start without a bump, but with a slight bump right when hitting the ignition it will fire in less than a revolution.

 

Mine will start without it but likes it under 30 deg.
