Sounds like the red diesel was heavily contaminated with something, you might have been better putting cooking oil in it Spry or the likes.

Yes I agree, that would be the simplest and cheapest first option.

If it's in the limp mode then a diagnostic check and reset of the system, seems the next logical step, does it run smoothly? albeit slowly upto 30 MPH?

it runs perfect up to 30 power everything over that it dies light comes on then you have to bump start it again it will run all day ticking over been pluged in 4 times all the time same fault code low fuel rail circit

 

[gregers]

you might be able to clear the stored faults yourself by discounnecting the battery for approx 20 mins?MAKE sure you have your code for the radio.

 

[bonito]

fault codes have been removed by mechanic if i feather the accelorator it will do 45 mph but come to a roundabout or stop it will stop and cut out

 

[wotan]

The fact that it 'runs smoothly' would discount the possibility of faulty injectors, wich really only leaves the high pressure fuel pump, assuming the limp mode fault has been truly cleared.
If it is the pump then I would imagine it would be very expensive to buy new, a breakers yard would be your best option.

i was told if it was the pump take filter lid off and put oil in with the diesel and if it is the pump it will start guess what still no start ance again it will
used red diesel possable contaminated 1 gallon dieed 5 minutes later
only bump start
so all symptoms are
wont start on key
will only bump start
over 30 mph light comes on and car dies
removed all pipework cleend out cleened tank out
new filter
i now have bald patch on my head scratching it that much

 

[bonito]

hi i have just replaced the injectors and guess what it starts and im going to test drive it now see what happens

 

[wotan]

When you mention ...it won't start on the key, do you mean the engine does not turn over?
If this is the case then possibly it's being inhibited electrically, like a auto transmission car, wich will only start in P or N
If the engine does turn over but fails to fire, I cannot understand why it should then start with a bump start?
If you do manage to sort this problem out please let us know.
