Vauxhall Z22YH Engines
Having been the proud owner of a 2.2 Direct auto since Oct 2007 about 2 months ago it decided to die a death. At first it was annoying, but it soon became an opportunity to learn exactly what is under that bonnet. To start I got an £25 adapter of flea-bay to read the ECU code, once I had some inkling of the problem it was time to resolve it.
Firsly the local D(st)ealers price for repair was a whopping £871+VAT, ridiculous. Then when I tried to source the faulty part (fuel pump) myself I soon realised they were both rare and damn expensive. In the end I forked out just over £300 for one, again of flea-bay but the key thing is to make sure you buy a Continental pump NOT the Siemens branded one.
Secondly you need to change it, now this is something that initially filled me with a little fear. In fact the job was easy, the only difficult bit being the darn retaining clips (TIP: another pair of hands and 2 smallish flat head screw drivers does the trick!!!). Take out the Siemens one…
Once you get the old one out then replace it with the Continental model, and away you go! Not quite, it takes a while before the engine pressure gets back to normal, don’t drive it straightaway – let it idle until the dashboard warning light goes off (picture of car with a spanner). Then leave it running for a while to ensure no cut-outs into limp or dead mode.
My Vectra C is zooming again, oh and don’t forgot the silent (shhhhhh!), yes blinkin SILENT RECALL for all Z22YH engines for a new FUEL PRESSURE REGULATOR. This will be done by your local stealers for free, I suggest you ring in advance to ensure your engine type is covered by the recall.
Next, it’s the Throttle body and then the Mass Air Filter to sort out…perhaps a engine flush too. Need it running as sweetly as possible!
