No-crank & no-start diagnostics
Systematic starting and engine-management diagnosis for vehicles that do not crank, crank but will not start, or start intermittently.
If the starter does not turn the engine, we evaluate battery condition, voltage drop, starter control, relays, ignition authorization, park/neutral input, security status and module communication.
If the engine turns normally but does not run, testing may include crankshaft and camshaft signals, engine speed data, injector control, ignition, fuel delivery, immobilizer authorization and ECU powers and grounds.
If the ECU or another module does not communicate, we first verify its electrical and network conditions. Programming is performed only after the vehicle is ready for it.
Text the year, make, model, VIN, ZIP code, symptoms, parts already replaced and any scan report. Tell us whether the engine cranks and whether the security light behaves differently than normal.
