Peugeot Boxer fun...

[S2r]

I have a 2007 Peugeot Boxer 2.2, it's a motorhome so doesn't do many miles a year.

Last year, after driving for a couple of hours, it wouldn't start it just kept turning. AA recovered me to my local garage where it started the next day without a problem.

They changed the fuel filter, checked some other bits but couldn't find any codes.

I have done a number of small trips over the past year without incident, but then drove for an hour or so up the motorway and it would turn over but wouldn't start again so another call to the AA.

After leaving it over night on my drive, it starts.

Battery is around 12.5 to 13 volts, fuel is fresh, egr replaced in the last 12 months, regularly serviced, the mpg appears to have dropped recently but no obvious smoke.

Feels like a fueling issue, so injectors? Fuel pump relay?? Something else???

Obviously, it could be many things and can only really be diagnosed when it isn't starting.

Best guess from what you say would be to check for fuel at the injectors as a starting point, live data from a code reader should give you fuel rail pressures when cranking.

Fors transits with same engine had lots of problems with fuel metering valve (on pump). And pressure sensor on the rail. We would sell a pair a day at ford.

Maybe worth a look.

I didn't think that age had the transit engine?

ETA.
Were those transit engines also the ones that used to gum up the injectors?

Might be wrong on that year. But i always thought 07-14 boxers had a 2.2 based on the ford 2.2 "puma" engine.
