No crank
The engine does not turn when the key or start button is used. Battery, cable, control, security, and starter circuits are tested.
No-start testing · We come to you
Vehicle won’t start?
Test it where it sits.
Avoid replacing a battery, starter, fuel pump, or sensor on a guess. We separate no-crank from crank-no-start conditions and test the system responsible.
When to call
Problems we
handle.
Truth Mobile Diagnostics focuses on evidence-based testing. We verify the complaint, test the affected system, and explain what the results support before recommending a repair.
Cranks but will not start
The engine turns but does not run. Fuel, spark, injector control, compression, timing, and security inputs may be checked.
Intermittent starting
The vehicle starts sometimes but fails under certain temperatures, key cycles, or operating conditions.
Starts and stalls
The engine runs briefly and shuts off, requiring testing of security, fuel delivery, sensor data, or module control.

Common questions
Before you book.
Do I need to tow the vehicle first?+
Usually not. The purpose of mobile no-start diagnosis is to test the vehicle where it is located.
Can you replace the starter or battery?+
Yes when testing confirms the failure and the repair is safe and practical at the location.
What if the vehicle starts before you arrive?+
Intermittent starting problems can still be evaluated using history, stored faults, voltage tests, and monitoring, but the fault may need to recur for final confirmation.
Will you just jump-start it?+
A jump may be used as part of testing, but the service is diagnosis—not merely roadside assistance.
