Time for more of our favorite thing...VIRTUAL DIAGNOSTICS!!!!
Here's what I've got today:
Have a Jasper DT466E in a 2000, engine has about 30,000 miles on it. We got the running complete unit...meaning it had everything it needed to drop in the frame and go, minus the bolt-on accessories.
Problem lies in cold starting. Even when it's 70 degrees outside, the thing still coughs and sputters and blows white smoke until it gets a little warm.
For what it's worth, I've always thought that the fuel system didn't sound quite right. I guess the best description I can give is this...imagine that fluid-like chatter of the injectors, only more course.
Any ideas on thing we can check or try? |

Check the fuel supply pressure and the injection control pressure.
I hope the valve timing isn't off. |
If it doesn't fit, FORCE it.
If it breaks, well, it needed replacing anyway.

| Forgive my lack of experience with this engine...are these pressures checked with a manual gauge or would the ECM be able to give this info? |

Supply pressure is checked at the Schrader valve with a standard pressure gauge. 50-60 psi should register. If not, remove and inspect the rubber check valve above the 'rock catcher'.
ICP will display on the MDFleet program. |
If it doesn't fit, FORCE it.
If it breaks, well, it needed replacing anyway.
