No-start diagnostic review
A vehicle that will not start can have a module fault, but it can also have a power, ground, starter, fuel, ignition, immobilizer or network issue. The intake is designed to identify which facts the module test needs before a final service is proposed.
State whether the engine cranks, starts briefly, stalls, has no crank, or loses scan communication. Include the conditions before the failure, warning lamps, active and history codes, and what happens after codes are cleared.
Record the module part number and include scan-tool communication results along with any verified ECU power and ground readings. If a replacement ECU has been tried, include both module labels and explain what changed.
The bench review can assess the received module against the no-start complaint and determine whether testing, repair evaluation, cloning review or a vehicle-side diagnosis recommendation is appropriate. It cannot confirm an unrelated vehicle fault from the module alone.
The $150 diagnostic checkout covers intake, module identification, applicable communication review, visible inspection and estimate preparation. ECU REPAIR contacts you with the finding and any proposed next step before final work is approved.
Before shipping
No. A no-start is a symptom. Vehicle-side checks and the condition of the module received determine whether ECU service is appropriate.
If a replacement-module or cloning path is being considered, include both part numbers and describe whether the original ECU still communicates.
