Is Your 2004 Durango Running Rough?
If your 2004 Dodge Durango with the 4.7L engine is experiencing frustrating issues like stalling, erratic idling, a persistent check engine light, or a complete no-start condition, a failing Engine Control Module (ECM) is a very likely culprit. The ECM is the brain of your vehicle’s engine, controlling everything from fuel delivery and ignition timing to emissions systems. When it fails, it can cause a wide range of problems that can leave you stranded. Don’t let a faulty computer dictate your truck’s reliability. This direct-replacement engine computer is the definitive solution to restore your Durango’s performance and get you back on the road with confidence.
From the Diagnostic Bay
We had a 2004 Durango 4.7L towed in that was a real head-scratcher. The owner had replaced the crank sensor, cam sensor, and even the fuel pump, but it still had an intermittent no-start and would randomly stall while driving. The scanner showed a slew of confusing, unrelated codes. After verifying power and ground to the ECM, we connected a scope and saw a noisy 5-volt reference signal. A quick swap with one of our pre-programmed modules, and the truck fired up instantly and ran perfectly smooth. It’s a classic case of an internally failing computer causing ghost-like symptoms that send you chasing parts you don’t need. A new ECM was the correct fix all along.
