    1.7 Dti non start no fault code

    Hi all.
    Can anybody help on this.
    2002 1.7 DTI Sportive Van, Isuzu engine,
    About 6 months ago I had the problem with the fuel injection EDU packing up,
    I re soldered the dry joints and job sorted, running again, that was until about 3 weeks ago,
    same problem, went out to the van in the morning and it just turned over, not a glimmer.
    Whipped the EDU off again and checked for more dry joints all looked ok so tried the EDU on another van, the other van started first crack.
    Fit it back to my van still no start.
    Checked for fault codes = 0571 Brake switch circuit malfunction.
    Sure enough when I checked I had a brake light out, sorted that and cleared the fault code. still no start.
    Then I noticed this posted by jcastraDti

    1. Take the top off the fuel filter housing
    2. Fill it up to the brim with diesel and replace housing lid securely.
    3. Foot hard down on the accellerator
    4. Start the car and keep your foot planted to the floor on the accellator
    5. Keep revs high (around 4000rpm) for a couple of minutes
    6. Then just let it tick over for 10min or so

    Gave it a couple of attempts and it started, this was Saturday,
    it ran until Tuesday morning and then same again just turned over but wouldn’t start.
    Went through same procedure as before also gave it a little sniff of easy start, but nothing.
    I’ve checked for fuel leaks
    Cracked the injectors, no fuel.
    There are no fault codes showing (on lap top or using the peddles)
    But it still wont start.
    Anybody got any ideas???

    Hi ya,
    whip the control unit off again and try it on your mates van, if it goes then it's not that.

    Then take the top off the fuel filter again and check how full the filter housing is.

    If it's low then the fuel must be draining back over time or you have air getting into the fuel system from somewhere.

    Fill to the brim again, replace top, then try to start, if it goes you know t the fuel pump is ok, then you just got to find the air leak.

    It might not have started up on easy start because the route was to long.

    What fuel lines have you got, if you have the cloth covered rubber type CHANGE IT, it's crap the rubber perishes and suck in more air than a whore on overtime.

    Tried to start it again last night, must have give it a go 5 or 6 times till battery stated to go flat, nothing.
    going to try EDU again on a different van today if thats OK looks like it's going to be a hefty bill for the fuel pump.

    Well other van started ok
    so looks like it's the fuel pump.
    just a thought but is the any way of testing if there is a signal from the main ECU to the fuel injection EDU or should I get a fault code if there wasn't ???

    Hi ya,

    go straight to the fuel pump, and test for your battery live, ECU live and your earths from the plug to the pump.

    If you have all your lives and earths, make sure that your battery is fully charged up,

    Place your hand on the top of the pump then get someone to switch the ignition on, you should feel it prime up,

    if not, get the person to crank the engine over while you give the pump a sharp wack, or get underneath and wack the center of the fuel tank,

    sometimes it get the pump running again, if it goes then at least you know that you have found the fault.

    Dave

    Only just got chance to have a quick look tonight and the pump doesn't seem to be doing anything when you turn the ignition on. It's going to be the weekend before I get chance to have another look, at this rate I'm going to be still doing this next Xmas.

    Well, just to tye this thread up.
    I had enough of getting no where so off to the diesel engineers with the f**king thing.
    turns out after 5 days of them messing with it, it was the crank sensor.
    Hopefully if anyone has the same problem reading this may help.
