Question 1

Why does my engine crank but not start only sometimes?

Accepted Answer

Intermittent crank-no-start faults are almost always electrical. The most common causes are a failing crankshaft position sensor that drops signal when hot, a fuel pump or relay that cuts out under load, an immobiliser that loses its transponder signal, or a poor earth connection on the ECU supply. Because the fault is intermittent, it only shows under specific conditions — that is why live-data capture while the fault is happening is essential.

Question 2

How much does electrical fault diagnosis cost in Wood Green?

Accepted Answer

MnF Motors charges a transparent, fixed diagnostic fee. Unlike chain garages that charge a generic 'health check' and fit parts speculatively, we use live oscilloscope and scan-tool data to confirm the exact fault before quoting repair costs. Call us on 020 8803 1231 for current pricing.

Question 3

Can MnF Motors come to Wood Green, or do I need to get the car to Edmonton?

Accepted Answer

Our workshop is at Unit 13 Shaftesbury Road, Edmonton N18 1SW — about 10 minutes from Wood Green. If your car will not start at all, we can advise on recovery options. Call 020 8803 1231 and we will help you figure out the easiest route to get diagnosed.

Question 4

Is it safe to keep driving if my engine occasionally cranks but will not start?

Accepted Answer

An intermittent no-start is unpredictable by definition — it will eventually leave you stranded, possibly in a dangerous location. A failing crank sensor in particular can cause the engine to cut out at speed, not just at start-up. Get it diagnosed before that happens.

Question 5

Will the fault show a warning light or stored code?

Accepted Answer

Not always. Intermittent faults sometimes store a pending code that clears itself, or they produce no code at all because the ECU only logs a fault once a threshold is crossed a set number of times. That is why live-data monitoring — rather than just a code read — is the only reliable way to catch what is happening.
