If you have serviced the engine, changed oil and oil filter and air filter and spark plugs and cleaned the carburettor or cleaned your throttle body and injectors, and its still heavy on fuel then try the following. Adjust the carburettor air and fuel. Take off the distributor cap and clean the rotor and spark pionts in the cap of carbon build up by means of light sand paper. Same applies to the spark/ high tension leads and coil lead metal connection points. Check distributor timing as well. If the engine smokes, do a compression test. If results are beneath factory specifications, remove cylinder head, replace the valve stem seals and re-seat the valves and or replace the pistons and piston rings. Basically engine overhall
petrol or diesel if petrol check plugs coil packs and leeds if diesel cloged injectors water in tank (change filter ) sticking valves timeing wrong head gasket could be a number of things but get the first couple checked first hope this helps ivan
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
OK WHEN YOU CHANG ANY FUEL PUMPS YOU NEED TO CHANGE THE GASKET AS THE OLD GASKET GETS EXPOSED TO THE AIR AND EXPANDS WHICH THEN LETS AIR IN IF THE CAR IS ON PETROL THE PUT IRIDIUM PLUGS IN A BMG AIR FILTER(THIS AIR FILTER IS NON THROW AWAY) THEN THE SPARK PLUG LEADS CHANGE THEM TO 10MM TOP GUN PRO RACE SERIES IGNITION SPARK PLUG LEADS THEN LOOK AT AFTER MARKET COLD AIR INTAKE PUT PRO RACE FUEL ADDITIVE PUT THE WHOLE BOTTEL IN AS THERE COULD BE SMALL PARTICALS IN THE FUEL LINES AND INJECTORS IF ALL THIS SOUNDS OVERBOAD THEN YOU COULD TRY REMOVING THE FUEL IJECTORS AND REPLACE THEM WITH GOOD QUALITY ONES UNFORTIANTLY THESE DAYS THE PETROLS WE PUT IN OUR CAR ARE FULL OF CRASP AND CAN BE VERY ABBRASIVE
