Hi Folks,
My Scudo 1.6 turbo (HDI) engine cut out at 60mph near the end of a 70mile drive
My fault code reader says p0192 Fuel Rail Pressure low.
I loosened a fuel injector pipe nut and turned the engine over,
No fuel appeared. checked that the timing belt was intact.
Was advised that the high pressure pump needed replacing,
replaced that, What A Nightmare Job, but done and no change.
still wont start. blew out the fuel pipes, and made sure there was no air in any of the pipes,

Don't have anything to measure the rail pressure except the scan tool which seemed to say 5000psi while cranking after replacing the pump.
the fuel filter was full.
I also bypassed it to make sure it wasn't blocked.
One of the first things I checked was for leaks and found none.
still no joy .
Anyone got any ideas? lost 2 days work and cant afford to lose more. any help appreicated. Regards D.

Has 5000 psi in rail when cranking


But still worth a booster cable start..or a tow
As RPM will help boost rail pressure


Lots of trying can tail off battrry power

Hi, Battery is fine, got a proper garage booster and its nearly new, still cant understand why it just stopped, TBH the high pressure pump seemed the same as the new one when turned over so don't think that was the fault :-(

Hi Folks,
Problem Solved, it was a faulty fuel rail pressure sensor, bit of a pig to get to, but it did the trick. hope this helps someone else.

Regards Donald.

Good news

So what pressures is it now showing?

Be good info for somebody looking in the future

Hi, the pressure now showing is 25000-150000 KPa or 5000-30000psi
but I now have another problem, Lack of power, it revs fine but no torque. i suspect a boost leak but can't find one. the scan tool shows a max of 5psi while driving, is this normal? what boost pressure should I expect? and where is it measured? at the turbo or inlet manifold?
Cheers, Donald.

Boost pressure should be measured by the map sensor probably on the I let manifold someplace could be worth removing it and giving it a gentle clean
