Frequently Asked Questions
How Do I Know if My Truck Has a Electrical or Mechanical Problem?
If your truck won’t start, has flickering lights, warning codes or unresponsive dash controls it’s likely a electrical issue. A full scan will tell you if it’s the ECU, alternator, battery or wiring.

We do ECM diagnostics and reprogramming to fix software related failures and performance optimization. In some cases ECM repair is possible but if the unit is totally faulty we recommend an OEM replacement for reliability.
