I'm having nothing but problems with my wife's Corsa C. It's the 1.0l 12v. I drained the battery listening to the radio when doing work for it's recent MOT. I recharged and it ran lumpy, mis-fired at low revs and lacked power. Two days later I went to start it in the morning and it wouldn't even fire. I've checked for a spark and all three plugs are firing fine, also fuel is reaching the cylinders but it just won't fire at all. I've even tried towing it and nothing.
All electricians I've spoken with tell me to bring it in and they'll have a look, no doubt costing me a fortune in the process and I'd prefer to narrow it down if I can before being compelled to dig deep!
It just turns as normal but with no hint of firing at all. It's the original battery but I had jump leads on it last night and also tried to tow but there wasn't a hint of it even firing. The car ran fine before the battery went flat, since then it spluttered for a couple of days, had no power and then died.
When I take the plugs out and attach them to the coil pack and rest them on the cylinder head, I get a spark. There is also fuel reaching the cylinders as the plugs are wet when they are taken out for inspection.
I've disconnected the connectors which control the injectors and taken the plugs out and turned it over to eliminate as much excess petrol as I can without adding more at the same time, (and there was a fair bit). I dried off the plugs put them back in and turned it to try and burn off the remainder and it fires ok, just doesn't start. When I reconnect the injectors it doesn't fire.
Where is the oxygen sensor? Is this the one of the manifold? If so, do I remove it completely or just unplug it? (excuse the ignorance but I am used to old Landrovers, distributors and things less computerised).
I've tried removing the fuse and it certainly fires but does not take. Excuse my dumbness but I presume that these fuel pumps are designed to halt all flow of fuel if they are disconnected at the injectors or with the fuse being taken out?
I can't get the oxy sensor out as the bottom bolt is solid.
I think the MAF is gubbed as the car was running very poorly before it conked out. It had no power and struggled along the road. It all happened after I let the battery go dead. Would a faulty MAF alone be enough for it to refuse to start? I've tried to start it with the MAF off the car and it fires as usual but does not take.
Hi, I'm having the exact same problem. I have a feeling its the timing chain. What did you find out? how expensive was the repair?
Hey mate, if you had to disconnect the battery, the cheapest a most cost effective move is to join the AA and ask them to come out. When you disconnect the battery it kicks the sensors and computer out of touch and you need to reset the service codes before it will operate properly. Hope this helps.
