P1833 Code

Perhaps the major effect of injector letdown is due to the injectors taking extreme return flow or back leakage.

This reasons a drop in rail compression which consequences in hard starting or not starting at all. You should check these things: Fuel Composition Sensor Circuit Malfunction, Cylinder 1 Injector Circuit Low and Crankshaft Position Sensor B Circuit Malfunction. Fix the car engine properly and solve the car engine. Test the car engine when you need to know that the car engine is ok.
