Default RAC man suspects fuel rail sensor….

Thought I had cam sensor issue. Non start when warm. Eventually starts after cranking 6-8 times. Visited Lancaster and got back to car. No start at all! Changed old for new sensor, still no joy! Damn. Called RAC and he (after checking fuel wasn’t the issue (UBP fine, fuel getting to it etc) he sprayed Easy Start into air intake and it starts! He thinks it’s the fuel rail sensor. I tend to agree. Where can I get one please folks? Car may or may not start in the morning for work so will need quick postage from somewhere!

I would suspect low fuel pressure to be the cause rather than the sensor itself.

Exactly as Trikey says. Especially if it fires up on Easy Start and then keeps on running.

It’s now started to stall.
Maybe low fuel pressure due to solenoid seal going?
Anyone nearby who could assist in fitting new seal and pressure sensor?

I’m still off the road and now relying on lifts, taxis and have now just booked a week’s car hire. This issue is going badly for me and the other half. Despite this we still want to keep the car going as we’re sure that is just a simple problem but its just getting the dots joined up/planets in alignment to get parts fitted. Garages around here are either far too busy or, in 2 cases, think I should go to a diesel specialist!

Hi Richard.
Have you tried to contact bigruss whom is the nearest to you with T4 and can most likely sort this out for you, got to be worth a try surely.

Highly unlikely to be the sensor itself. I would suspect the HP regulator solenoid seal on the fuel high pressure pump, There is a kit from www.darwendiesels.com CMR 1700-9 for Bosch CR-1 pump.

Do a search herein.

RAC did mention low fuel pressure hence his nod to the sensor.
Lee T replaced this not that long ago, in May. He said it’s a Regulator kit for HPFP. Some sort of seal kit.

Can I unplug it like the MAF?

Hi Richard.
As anyone done a leak back test on your car yet, if not get one done, also even though you the RAC says the UBFP is ok if you have less than a 1/4 tank of fuel it can struggle.

If you suspect the fuel rail sensor ? then drop mickyboy a PM and see if he can send you a good used one out asap, be best if you could get it on T4.

I presume this is the O-rings that Lee fitted to the regulator.
https://www.ebay.co.uk/itm/334135381254

I doubt he did a full refurb on the HPFP.

Hi there Arctic!

Lee T did that in May. I don’t suspect any injector issue. Replaced 2. The others were - one was guite good and one was good.
Also the RAC man connected up to the plug by the drivers knee area (forgotten what it’s called!) and no errors except for ‘Can’ which he couldn’t clear??
