my dear wife filled our freelander td4 with petrol and drove it home about 3 miles.the first thing i said to her was have you filled it with petrol no she replied dont be stupid so i left it at that.the next day i tried all day trying to get it started then just as i was for giving up my boss came along and said sniff the fuel cap it was reaking of petrol so after a near devorce i set about it by emptying the tank changed filter run pumps until diesel was present at the rail it now wont fire diagnostics came up as no fuel pressure should i asume the high pressure pump (injector pump) is now buggerd or is there somthing that needs reset i also cleaned fuel rail pressure sensor.

how long have you tried cranking might take a bit to get the air out of the system,have you tried cracking an injector pipe or rail feed
 
cranked the battery flat twice i cracked open the injector pipe the fuel only comes through at the rate of the low pressure pump slightly more when cranking.
 
If its any comfort I did the same to a Saab 93 diesel a few years ago, drove it straight onto the motorway after putting a full tank of unleaded into it.
Expired after about five miles, got recovered, drained down etc. After it was back on the road, I kept it for another 40,000 miles, never missed a beat!
So fingers crossed yours wont have suffered any permanent damage.

if anythings damaged it will be hp pump ,but try cranking with feed for rail off and see if its has air ,it wont pump large flow but high pressure or should do
 
hopefully not mark i think its done the hp pump as its not getting enough pressure to fire ive done a light bulb test on the injector loom to no avail.

i will try that i thought these were self priming should the diesel not be high pressured at the rail.
 
I think you can keep switching the ignition on and off. This should purge the system of air without excessive battery drain. However once you have diesel at the HP pump, you have to crank the engine. I wouldn't have thought the HP pump would be damaged in such a short distance. I add 2 stroke oil to the diesel in cases like this to reduce pump wear.
 
thanks for replies for all this car has put me through i still love it and to be fair it wasnt the cars fault this time lol.
 
The fuel system is self-bleeding in that you don't need to crack open any pipes or such to get the air out.

The way to do it is to turn on the ignition, but do not attempt to start the engine - you should hear the fuel pump whirring away and may even hear liquid moving through the pipes.

After on and a half to two minutes the pump will automatically shut off - but the air will NOT all be bled out by then - so you need to wait for 5 minutes then go through the above procedure again.

I would suggest that you repeat the bleeding sequence of switching on and waiting for the pump to shut off perhaps 5 o6 times times before turning the key to try a proper start-up attempt.

Good luck - keep us posted.

Sorry i can't suggest any further things to try.

no but the amount of fuel and its flow are important to see if you want to know pumps working properly otherwise you have no idea if it fuel to hp pump or from it where the issue is,
 
it is a pity she filled it ,if it had only been a couple of gallons then you could have filled it and got away with it , but do not be too hard on the wife as we all make mistakes, I nearly have with the wife freelander as mine is a TD4 and hers is petrol and both the same colour I have to look at the back window as mine is a sticker in it saying diesel.
