Installed GDP pump with 2 mic filter and had some cp3 work done. Truck cranked up and ran for a few minutes then died. Put 5 gallons of diesel in it and still will not start. Its given me a crankshaft performance code even after i clear it with my BDDL. Ive returned it to stock, same thing. Im gettin fuel to cp3 and injectors, but will not start. We pulled the battery cables and now it gives a camshaft performance code. We are testing the injectors and waiting on the new sensors to come in. If anyone knows something im missing, PLEASE HELP!!! Thanks in advance.

 

List all the codes, there should be a series of P10xx, P11xx, and p12xx that will cluster when the injection system fails to sync with the camshaft sensor impulses.

Most frequently what happens is the power line to the OEM lift pump has a ground or excessive load that is pulling down the voltage available to the injectors, and that causes the sensor to generate an error code. However, it can also be dirt under the valve seat in the rail pressure relief that will cause the same symptom.
