Cmax titanium 2013 diesel with push 'power' button to start

This answer was rated:

Cmax titanium 2013 diesel with push 'power' button to start (and press clutch). Had it 3 days. Today left it unlocked while in a shop for 15 mins & on return turned over fine but would not fire. Tried locking and unlocking with remote - no luck. After about an hour it just started ok. Quick check revealed no fault codes but saw 'Engine fault - service now' on info didplay a couple of times. 3rd time its done this now, previously was when i pressed power button to try and liven up radio/mirrors. Then on clutch press to start it just turned over not firing. Each time after an hour or so it started normally. Ideas please?

Dealer today used proper diagnostic tool and said a fault had been stored relating to fuel pressure, so changed fuel filter. I suspect that was 'on spec' and will try to reproduce fault as above before accepting. Need another/expert opinion.

Hi Mike,

If the dealer says fuel pressure, they should be looking at the whole system, including the rail pressure sensor data.

The Ford data tool can log this on a road test.

The tech should be able to tell under what conditions the code set.

Engine turns over, no start. If it was your car what would you suspect? Is it possibly anything to do with the immobiliser?

Hi Mike,

Could be immobilzer related, but should log a code in one or more modules.

Could be a low pressure fuel pump relay, poor contact in the fusebox etc.

Difficult while it is intermittent, it will become easier once the fault is repeatable.

Have you ever experienced this fault or anything similar before? What was the cause?

Hi Mike,

Not on your model so far, but others are similar.

Being now 3 years old, I would look at the battery cranking voltage, and whether the immobilizer is reading the key correctly.

It could also have the start of a low pressure fuel pump failing.

I do hope it is not a high pressure pump issue.

Thanks

Hi Mike,

Your dealer should keep your car overnight for more testing.

Cold starts, warm restarts etc, different scenarios.

I hope my advice has been of assistance to you.

Kind regards
