Why is my diesel truck in limp mode?
What are the causes of limp mode? Limp mode is triggered by the car’s computer, which receives signals from all the different components of the car. Problems which cause signals like this are usually faulty engine sensors/components/wiring, transmission issues, dysfunctional brakes and clutch, or even low fluid levels.
How do you test a CP3 pump?
You can simiulate max output for the CP3 by unplugging the FPR and fuel sensor. This forces the CP3 to put max output on the fuel rail. To do the check you will have to pull you glow plugs and watch excessive fuel from coming out the glow plug holes.
How long does a CP3 pump last?
Cp3 can go a long time more than that. 150,000 miles is the average life span of a common rail injection system, not just the LB7. The nozzle tips erode over time and the fuel spray gets distorted, mileage drops, and over all performance weakens.

Can a 2003 Cummins have a hard start?
One of the most common calls we get are from customers with a 2003-2007 Cummins that have developed either a hard start or no start condition. In order to help out, we had our very own Tyler Lucas, put together this step by step tutorial that you will hopefully find insightful.
What causes a ram truck to not start?

A lack of lift pump flow will not only cause a no start issue, but depending on how it failed, can cause other issues that we will discuss further into this post. The factory lift pumps on the 2003-2007 Cummins produce a dismal 10-11.5 PSI at idle.
What kind of pump does a 2003 Cummins truck have?

For reference, the 2003-2004.5 trucks came equipped with a block mounted lift pump and the 2005-2007 trucks came from the factory with an in-tank lift pump, yet many of the 2003-2004.5 trucks were later retrofitted with this same in-tank design.
What should the battery voltage be on a 2003 Cummins?
It is very common to have a battery read around twelve volts on a surface charge, but then drop well below nine (the minimum voltage to allow for cranking on 2003 to current Cummins) when under load. Overall, make sure that when you test the battery, you are doing so under load by cranking the engine and watching the voltmeter.
