Hi peeps, I'm new to this so bear with me.... bought an Astra 1.7 CDTI 2005, all good and ran ok, a week into owning it it won't start, turns over but that's all, I've changed the relay and all glow plugs and am waiting on a decent heavy duty battery. I'm looking at replacing the fuel pump and possibly the injectors but failing that I have no idea what the issue is. No fuses are faulty and no error codes on the dash. I do have a wire with a black and green plug at the end hanging out of the fuse box under the bonnet but couldn't tell you if it was attached when I bought it! When I work it out I'll post a pic. Any help muchly appreciated! Cheers , Michael
