Hi all, im after some advice, but firstly, id like to say what a great help these forums have been to me over the last couple years with my old smiley
I own a 06 plate transit TDCI 125 (2.0l diesel), and am having a few issues with the glowplug flashing.
Brief history of the van, bought last year from trade seller, 200k on the clock. Found out it had a botched repair from a snapped cam chain, so a replacement engine was fitted (not sure what parts, but at least new block and head. Injectors and pump all set up OK (think it had 1 new injector))
Van is now at 265k, and not long after a routine service, it started losing power.
Have had it plugged in, and codes P0251 and P1211 have come up. Codes cleared, but came back after the next run out.
Took into local independant specialist (very good, have used for years) who plugged it in and tested various sensors. They came back with the following:-
No pre supply pump, HP pump sucks from tank (there is a definate HISS of air when filter is bled, so is airtight)
HP pump supplying at around 1500 PSI at cranking speed.
injector leak off test all ok
No faults with any sensors.
Fuel pressure regulator on the pump was showing erratic readings, so was changed.
Injectors not yet had a full pressure test done.
Unfortunatly, we cannot seem to get the problem to replicate when he has the van, but it seems to occur more often when carrying a heavy load, with a hot engine, accelerating in 5th from 60mph upwards.
The van generally seems to lack power when you want it, as if its being 'Choked'. Starts and idles perfectly, accelerates 1st through 3rd fine, struggles in 4th, almost no acceleration in 5th.
It doesnt misfire, but seems as if its not got any fuel?!?! (if that makes sense)
Can anybody PLEASE help, as its doing my nut it!!
