idle surge then dies at start up

Anotger member may come along with a smoking gun.
But, usually when I have a 24v that has a starting issue similar to yours, it usually indicates an injection pump in the process of failing.
Its possible that that it’s s sensor, an intermittent short, an ecm issue, and a handful of other things. But most times your symptoms are indicative of a vp44 issue.
Do do you know how to isolate the injection pump from the ecm to illuminate that possibility?
I can type it up tomorrow if you don’t. I just walked in from my shop or I’d do it now.

What Lift pump do you have in truck. Usually if you have fuel drain due to leak or bad pump its a long start not a start surge then die. cycle the key and see what codes slide through the odometer. Sounds like a bad VP. especially if you had to put in a new lift pump due to the old one being bad, coudlve fried the ECM on the pump
