Vehicle Starts Then Stalls? Here's Why

---

Some vehicles start, stumble, and immediately shut off—especially after parts replacement or dead battery events. This isn't a guessing game. 

At Keeney Auto & Diesel, these symptoms are approached with precision: 

• Scanner access to security data
• Scope verification of fuel delivery
• Evaluation of airflow
• Ignition behavior from startup onward

Whether it’s anti-theft, fuel pressure drop-off, sensor faults, or idle air control issues, here the failure mode is replicated, traced, and proven. No unnecessary part swaps. Just the right diagnostics, done right.

Having trouble keeping it running after a start? That’s where real testing finds what others miss.
