However, I can help you narrow down the possible causes of the engine light and lack of power. Here's what could be going on:
Possible Causes of Engine Light and No Power in a 2007 Cummins:
* Fuel System Issues:
* Clogged fuel filter: A dirty fuel filter can restrict fuel flow and cause power loss.
* Fuel pump failure: A faulty fuel pump can't deliver enough fuel to the engine.
* Fuel pressure regulator issues: A malfunctioning regulator can create inconsistent fuel pressure.
* Water in fuel: Contaminated fuel can damage injectors and cause problems.
* Electrical System Issues:
* Faulty sensors: Sensors like the oxygen sensor, MAP sensor, or crankshaft position sensor can send incorrect information to the engine control module (ECM), leading to engine problems.
* Loose or corroded wiring: Damaged wiring can disrupt electrical signals and affect engine performance.
* ECM malfunction: The ECM itself could be faulty, causing various engine problems.
* Engine Mechanical Issues:
* Turbocharger failure: A malfunctioning turbocharger can reduce air flow and power output.
* Exhaust gas recirculation (EGR) system issues: Problems with the EGR system can reduce engine power.
* Intercooler problems: A damaged intercooler can affect air intake and engine performance.
* Other Possibilities:
* Engine air intake restriction: A clogged air filter or other intake obstruction can restrict air flow.
* Vacuum leaks: Leaks in the vacuum system can disrupt engine operation.
What You Should Do:
1. Check the Engine Light Codes: Use an OBD-II scanner to retrieve the diagnostic trouble codes (DTCs) stored by your engine's control module. These codes can provide valuable clues about the issue.
2. Inspect for Obvious Issues: Check the fuel filter, air filter, and other easily accessible components for signs of dirt, damage, or blockage.
3. Consult a Mechanic: It's best to consult a qualified mechanic to diagnose and repair the problem. They have the tools, experience, and knowledge to accurately identify and fix the issue.
Remember, attempting to diagnose and repair your engine yourself without proper training and equipment can be dangerous and may lead to further damage. Always prioritize safety and seek professional help when needed.
