Turn the key until you have all the dash lights on but DO NOT start the car. You should here the fuel pump activating. Wait a few seconds (the longer the better) then try to start the car. If it starts with no problems you have a fuel pressure leak somewhere, most likely the fuel accumulator, check valve at the fuel pump, leaky fuel injector/seal among other things. If you want more specific help, have your mechanic do a fuel pressure test...Good luck!
