Question 1

Why does my car crank but not start intermittently?

Accepted Answer

The most common causes are a failing crankshaft position sensor, a worn fuel pump or faulty fuel relay, an immobiliser communication fault, or a dropping voltage on the ECU power supply. Because the fault comes and goes, live data capture during the failure is the only reliable way to confirm which system is responsible.

Question 2

How much does electrical fault diagnosis cost in Waltham Cross?

Accepted Answer

MnF Motors charges a transparent diagnostic fee that is confirmed before any work begins. For most intermittent no-start faults the diagnostic session takes one to two hours. Call 020 8803 1231 or use the online quote form for a firm price before you book.

Question 3

Is it safe to keep driving when my car cranks but won't start intermittently?

Accepted Answer

It depends on where and when the fault strikes. An intermittent no-start becomes a stranded-vehicle situation without warning — potentially in traffic or at night. We recommend booking a diagnostic before the fault becomes permanent.

Question 5

Accepted Answer

A thorough diagnostic session — including stored code retrieval, live data monitoring and component testing — typically takes one to two hours. If the fault recurs during testing we can often confirm the root cause the same day.
