assuming things were working okay and u aint altered things since u parked up..
if the main pump isnt working the residual fuel pressure in the system isnt enough to work the main injectors but it is enough to work the extra cold start injector.. so if its the main pump thats the problem ie not working.. when u first turn the key the engine will give a brief cough from the fuel being squirted in from the cold start injector but no more cos the main injectors wont work.. this one is simple.. the brief cough and then nothing tells u the story..
if the main pump is okay but say the cold start injector is leaking or even one of the main injectors is leaking over-night.. due to the residual pressure in the system the system will be over rich and have too much fuel in the mainfold before the key is even turned and the cold start injector squirting an extra dollop in there will mean one dead car that makes no attempt to fire at all.. ie.. no little cough at the start..
i wouldnt dream of mentioning the myriad of other "simple" things that one should check first of course..
remind me to keep out of "my car wont start sometimes" threads... he he he
