I have a 2004 chevy impala. My car has a delay in starting up. Sometimes it starts up right away and other times it can take up to 15 minutes and many tries before it starts up. When i try to turn the car on everything else works but the engine, the radio, lights, locks comes on as intended-so i dont think it has anything to do with the battery. Also, when i attempt to start the car, it does not make any harsh noises-it just sounds like air and then a rolling sound. Recently my gas guage has started to read incorrectly-i cant tell if i have a full tank or not. I dont know if this has anything to do with the car not starting. Please give me your advise...Thank you.

Next time it refuses to start duplicate the problem and do below

Get a starting fluid or ether and spray into the carb or the throttle body on an EFI. Did it start and die? If not disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs,distributor pick-up coil, ignition control module, cam and crank sensors- Note: If it doesn't apply disregard it
