If you just unplugged the Edge but didn't plug the map sensor back to the block the truck wouldn't recieve a signal because the map signal goes through the Edge.

Sets a fault then goes into limp mode where you can maybe go 20mph if your lucky

Yeah, that's it !! Do you think it's the Edge or something else?

I only unplugged the harness from the Edge, not from the MAP sensor. Did I also hafta unplug it from the MAP sensor as well? If I did that, would I then have to put that MAP cap back on the sensor? The MAP cord just had a cap of some sort on it before I plugged the Edge onto it.

i have a 2000 dodge 2500 cummins i put edge juice on it and 2 days later i turned it up and got on it and then it died i think i fryed the injector pump any ideas? fuel pressure was low like 5.

5psi is fine at wot. You may be having a bad connection on your pump wire.

My truck did the same thing a few weeks ago. Right after I was taken it easy on her. But since then I have got on it a few times and it hasnt happened since. I have been keeping an eye on it though.

I found out today the lift and injector pump is gone something inside of the lift pump was bad so guys if u have a cummins with 100 thousand miles or better put a lift pump on before a programmer it will save you money thanks bluecummins
