Question about 2003 Pontiac Sunfire

Open Question

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.

2003 pontiac sunfire makes clanking sound from engine, sounds like valves? lifters make more of a ticking sound...right?


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.

2003 sunfire won,t start, turns over but does not get spark, any suggestions would be greatly appreciated


Hi Alan, Have the vehicle scanned with a diagnostic scan tool. The problem may be a crankshaft or camshaft pickup sensor. The scan will pinpoint where the problem is. Regards John

My 2000 pontiac sunfire wont start when i turn the key. It just makes a continuous clicking noise for as long as I hold the key trying to start it. The. Starter had problems before but than it


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.

2003 Pontiac Sunfire - When I turn the ignition on the dash buzzes, kind of like an alarm or a loud whirring noise. The gauges do not come up right away. If I leave it for a second or 2 it will sputter...


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.

Sunfire will not start, it started for a second or two then quits could it be the fuel pump or ecm or anti theft shutting the fuel pump off i am totally baffled, 2002 pontiac sunfire


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.

2003 pontiac sunfire, key in ignition nothing. tried jumping, nothing. Left for help, came back car started right up 4 or 5 times, Now nothing. Why? ty, Sue


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.

Sunfire won't start


Have you local gm dealer run your vin "vehicle identification number" on there computer to see if the starter recall was done on it. If it has been done it sounds like it could be a bad starter.

My 1997 sunfire wont start. the engine will turn over.


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..
