I'll have to check the pump shaft should the engine run good when you run the hot wire mine runs rough when I do that

The injectors I put in are Bosch 275 hp i'm wondering if it's because the engine was cold when I tried it maybe I should warm it up first

Ok now I see it my truck runs with the hot wire bypass to the vp44 pump but it runs rough and idles at 900 rpm

Cummins tech your discripion says that pin 7 is on the bottom and your pic shows it on top can you clarify please

my truck is not throwing any codes at all only if I unplug something like the apps then it will other than the high idle and a very slight sputter when I rev it up alittle in neutral say 2000 rpm it runs great I will try a hot wire to the vp pump and see what results I get and let you guys know

How do I do a blue chip hot wire test? what trucks would have the same ecm as mine

Yep I set the apps sensor below tag limit I even unplugged it to see it would run off the soft wear in the computer and a reset of the apps but there's no change

I tighten the crossover tubes first then the injectors but this problem was happening before I changed them operating temp driving is 89 degrees Celsius is what my scanner is saying

Hi this is my first post on this site so please bare with me I have a 2002 Dodge Ram Cummins 1 ton 6 speed manual it idles at 1000-1200 rpm with the engine hot or cold the only mods are a banks big hoss tuner and banks air intake I just replaced all six injectors, the lift pump, the cam sensor i've also checked the apps sensor with a multi meter and a scan tool the truck is not showing any codes other than a faulty air intake heater relay I'm not sure what to try next
