Hello all!
Ive been banging my head against a wall working on this truck for months and im running out of things to check. Really hoping for some advice.
2020 Ram Ecodiesel, Tradesman 4x4, ~160k miles.
Customer stated it wouldnt start and he wanted all EGR and DPF system removed.
Truck came in with a bunch of codes, all fuel related, power related and EGR/DPF related.
I failed to get the truck running before performing the delete, I was backed into a corner with time constraints so I opted to perform multiple repairs at once. I removed all EGR and DPF systems, installed the appropriate block off plates and had the ECM tuned. After completing the delete I was still getting codes for fuel and power. I replaced the lift pump (pressure was weak) and had the dealer replace the CP4 under the recall. I also replaced the battery and crankshaft position sensor (erratic signal graphed on my scanner).
All codes are gone with the exception of two stored/permanent codes (U1267 & U0100). All fuses and relays are good, ground is good, Cam and Crank signal is good, intake valve is open, fuel pressure is good.
After replacing the crankshaft sensor the truck actually started and idled for about 10-seconds, then it sounded like it choked out and died. it has not started since.
What should I check next??
Thank you in advance for any help you can provide!
