I have a corsa utility 1.4 petrol had twin spark plugs in changed it to single spark plugs i tried to start it but plugs get wet from fuel i put twin spark back and it starts very heavy on fuel

Put the old one back and try again. If faulty, fit an OEM part not a fleabay/amaxon part. They don't work!

When you first start the engine on these computer-bound vehicles nowadays, the computer automatically puts the engine into "cold start" mode. If the temperature sending unit/sensor is not telling the computer to turn off cold start mode, the engine is being flooded with gasoline. This is why your plugs are wet and won't fire. Change said sending unit and all will be well.

Could be many things, but start with the basics. Use fuel pressure test gauge to check for leak down after shutting engine off. Could be leaky injectors. Could also be weak spark preventing fuel from complete burn--bad coil or ignition module. More likely bad coolant temp sensor making ECU think engine is still cold after it is warmed up. Another possibility is clogged exhaust.

You must have a fault code test run first, that is the start point on all modern systems of engine control.

Hi my bakkie is wetting the plugs with patrol on a Opel corsa 1.4 please help me

try check fuel floater..

flooding out
incorrect injectors or bad injector seals

hi, you need to take the spark plags out and clean them. the air filter must be taken off and pour an egg cup full of petrol into the carburetter, this is very important not to put too much as this will WET the spark plug and you will need to press the thottle full bore while turning the engine over. try this to test if fuel, spark plugs, points / electronic ignition, ignition, firing order (leads the wrong way around), mechanical parts, all other wiring correct, gerry

hi, the cylinders are dry of petrol fumes and you need a (good battery), if all the mehanical parts (working fuel pump and clean fuel filter) o.k. and the spark plugs are clean and the (spark plug timming leads) are correct and points are set and the (ignition coil) is o.k. this engine should start. (if not) take off the air filter and check it is clean, leve the air filter off and put a very small amount (egg cup full) of clean petrol into port the carberreter (it will not start straight away because the plugs may be wet) or wrong (timming leads) if it splutters problebly not enough petrol or ignition faults (electrical points contacts dirty) all cars need metered fuel and air to run. wish you luck gerry

Pull one plug out of one cylinder, and place the top of the spark plug on the body of the car(grounded). Start(or have someone turn the car over) and hold the plug to a grounded spot. If the plug sparks it is not an electrical problem. Also, if the plugs are coming out wet, your flooding the engine making start even harder. Also make sure the plugs are gapped to manufacturer's spec.
