Need serious help.
I purchased this 2016 RAM Ecodiesel at an auction after cranking it over there, everything sounded healthy and I knew the tone rings on these were a common problem so I thought I’d roll the dice. Well I’ve been working on the truck about a month now and I’ve now replaced a stuck injector, replaced the glow plugs, replaced the tone ring, did the fuel filter, and have diagnosed everything I possibly know how. I am getting 4600psi at the rails, all injectors are good now, lift pump is pushing 60psi up to the CP4 tone ring is replaced and engine shows RPM when cranking…..I’m stumped.
Another mention is that this truck was deleted at some point, maybe the delete tune is hiding codes I don’t know can’t access any of that and I don’t want to spend $800+ for a tune file on a truck that doesn’t start. Weird symptoms though no codes but coolant temp shows -40 degrees (replaced the sensor too), it will light off starting fluid but won’t stay running at all.
Also did a leak down test showed no loss of air in cylinder + cylinder balance test checked out so compression is good (most likely).
If anyone has a tune they’d sell for cheap or knows something I don’t I would literally pay for the right advice
