Vauxhall Corsa engine turns over but wont start, keeps dying

To start this engine you'll need: air flow meter (if there is any), crankshaft sensor, cambelt sensor, compression and working spark plugs. First check what says ecu by flashing codes, ecu is smart and will tell you about any problem with any sensor, and much more. Good idea will be if you can check compression.
Sorry for my english.

first make sure the engine warning light is not flashing as this would indicate an immobiliser fault for example sometimes the key falls apart and the chip inside falls out.next getit fault code read as the crank sensor may be faulty or maby other things
