My 2003 pontiac sunfire is having problems starting
When I try to start my car, it won't start. I makes a weird buzzing sound, and sometimes a clicking sound. It doesn't do it all the time, and it drives fine once I'm going. I don't know if it has anything to do with the other, but also the rear brakelight doesn't work all the time, and I can't see my digital odomoter unless the light hits it just right. Also I don't have a dinger when I open my door.

valves do not normally make a sound unless the seat insert is loose in the head. This will be revealed by a compression test. I suspect that a clanking sound is much lower in the engine --like a big end failure.
first off does it have a remote starter hooked to it, if so disable it, my daughters car did the same thing till I took the remote out sometime the remote won't let you start manually in it is still engaged. next make sure all your connections are tight (battery ans starter, I bought a starter at a local parts store it was only acouple of months old for her car it started to do the same thing so I took it back and it failed their test ended up getting a new one. also check the rely located on the left fender wall it is marked starter it may be bad.
The problem could be a power supply module that supplies various voltages to the instrument panel (IPC). If it is acting up, it can make this buzzing noise. If that is it, it will eventually fail and the IPC gauges will stop working.
Have somebody listen at the gas cap for a buzzing sound when the ignition switch is turned on, or if you can hear it, it only does it for a few seconds, if you don't hear it, the pump is bad and the gas tank has to be dropped to change it.
This is not recomended, but I do it all the time to make sure the problem is in the fuel system. Spray a little bit of starting fluid in the intake, if it starts, the problem is in the fuel system, but listen for the buzz sound first.
Other problem could be a clogged fuel filter, or a faulty fuel pressure regulator. Have a fuel pressure test done, that would also reveal the problem, if it's a fuel problem.
Sounds like a short in the ignition switch. Next time it does it, try shaking and turning the steering wheel while you're turning the key to start. If this doesn't work, try cycling the switch on and off several times. Chances are, this is your problem.
its a sunfire , have a buddy sit in your car and you go to the back have him turn the key to the on position... not the run position and listen for a buzz or whiiirrrrrring sounds, do this several times if no noise chances are your fuel pump is dead, a common chev problem, if it has no noise you can try giving it a few good whacks where the fuel pump is located at the tank and try again more often than not this will get your fuel pump buzzing again and then you will know if your problem is at least in the front or the back.. yadidimean Thanks Shawn
