My truck hates me
My 06 cummins had an fcm internal and left trailer overcurrent code. Dealer said replace tipm, so i did. Now 1223 and 0248 codes are coming up. Wait to start light comes on and it looses power. What could the problem be? Fp is normal 6500 at idle wide open is around 22k. Truck runs fine untilthe light comes on.

Just for giggles, try cleaning up all of your ground cables/ wires. Good electrical contact is crutial to keeping your tipm and ecm happy. Start with battery cables and move on to all ground wires you can find in the engine bay. There are several. This is simple and doesnt cost anything but a little time.
