had very similar problem with my 2002 1.7 diesel astra
running home from shopping just came to a stop waited a bit it started and ran a few yards finally stopped altogether. Garage towed it to their work shop
Problem they said new main computer or pump required costing £200 to £500 pounds suggest scrap car. Got car home and thanks to your readers answers found and re soldered dry joint in pump ECU going Ok at the moment many thanks

Dear all. All vauxhall diesels have a very common fault. The car/van will keep cutting out and sometimes will start and drive for miles and sometimes just a couple of yards before cutting out again. Vauxhall will have you believe you need a new fuel pump and or fuel pump ecu and can cost you anything between £800 and £1200 and still not cure the problem. In very rare cases the fault may well be the pump but I haven't had one yet. My company can sort the problem for anyone with these symptons for a snip of Vauxhall's price at £300. For details call steve at S,C,M on 07737 175542. Thanks all.

I have exact same problem. Started yesterday, engine cut out, restarted a couple of times then cut out altogether. Had to get towed home. Googled the problem, found this article (and a few other websites too gave this same answer). Took the ecu off the back of the engine this morning, sure enough the soldering at the centre of the board was dry jointed and burnt the surrounding board. So i soldered a wire across the broken joint, put the thing back in the car. After a couple of attempts (by which time my heart had sunken again!), the engine fired up and has been running absolutely fine since. Took it on about 80 mile test run today and stopped the engine a few times to see woould it re-start and it has been giving no problems at all. So... THANK YOU VERY MUCH for this article!! The garage told me yesterday that it would cost €700 for a new pump + €300 labour + VAT!! And could not guarantee that would fix it, said the diagnostics aslo said possible ECU failure too. Early symptoms (I think) were an intermittant misfire, as if the engine cut out for about half a second, quite randomly, seemed to increase in regularity, until it did keep cutting out altogether. All seems well so far, only €160 down for the tow back home yesterday instead of a possible grand or more.
So thanks again - have faith all out there!!

hi mark, had what sounds like the same problem with my dads van. was it the main ecu on top of the engine that was replaced? there is also a second eco down the back of the engine which controls the diesel pump. very common fault with these is the soldering inside the diesel ecu breaks stopping the ciruit sending a signal. Remove the ecu - 4 bolts and unplug the wiring multiplug, prise off the back cover with a small screwdriver and have a look at the soldering on the ecu circuit board. If there looks like any breaks, resolder, put the back cover on and refit. If your not willing to try it yourself, various companies on ebay offer a service to carry it out if you send them your ecu. Also, if memory serves me right - fuse 16 i think - can fall out slightly from the fuse box, or be blown - in the right of the lower dash. Check this cos that also stopped a mates diesel van from running. Lets know how you get on.
