Question about 1998 Pontiac Sunfire

98 Sunfire 2.2L automatic 210,000km Starts and in a second stops, can do 20 starts and same thing. Pump can be heard loud and clear. Gas pedal to the floor or not it just won't keep running? Happened several times last year, but then ran fine after several attempts to start it. Haven't used the car for months after that, but now just won't keep running after it starts..

Try turning key to on (not start) 3 or 4 times first, ( to prime it more) then try start and see if it runs a little longer. If it's been sitting there is a chance gunk in tank has plugged up filter as well. Make sure you add some fresh gas, as well as some "Heet" to remove any moisture that may have collected as well in tank. If it continues to not start and run, you may need to have a fuel pressure test done to see if pressure is where it should be. Pump getting noisy is also a sign that it may be weak. If pressure is low, change filter first and try it. If no improvement, you'll need a new pump. You'll want a new filter on there if pump needs replacing anyway, so try changing it first, it just might do the trick.

I HAVE A 2004 AZTEK AND HAVE VIBRATION WHEN PRESSING GAS PEDAL. WHAT CAUSES THIS?


you don't say where the noise is. that is important to give a clue where the issue is. when stopping on the brakes 3 things happen. you press the pedal and the abs pump starts pumping fluid. the second is the brake capilers start pushing on the rotors to slow the car. the rotors are attached to the wheels and that stops the car. so if the rotors are warped you will feel a vibration in the steering wheel when stepping on the brakes. if its your foot feeling the pump working that is normal for abs pumping. you should feel it and holding the pedal will keep it working and stop you from skidding if everything is working correctly

Try cleaning the throttle body and butterfly plate. If that doesnt work, replace the IAC (idle air control) motor.

I am having problems starting my 2000 Olds Bravada in cold weather, even only 11-20 degrees. I have to pump the gas pedal in order for the vehicle to start, after a few tries. I can hear the pump working...


The pump is supposed to stop when the fuel rail has enough pressure so the 5 sec. thing is normal.Sounds like you need a throttle position senser replacement.

Fuel pump or filter possibly


the idle control sensor could be bad give these websites a try www.alldatadiy.com and www.autozone.com if all fails stop by your local GM dealership and ask for the manager and he can tell you what is going on if that fails stop by your local library and get your hands on a Haynes auto repair manual for you car wish you the best Michigan Man.

It takes a few seconds with the gas floored to get it going. once it is warm it starts fine. I did smell a faint gas smell a week ago. it has 50k miles on it. wondering what it is and what it should cost


Possibly a leaking fuel injector(s). When you floor the gas pedal when cranking it puts the computer into clear flood mode which shuts off the injectors.

98 pontiac Sunfire shuts self off


You might not need a tumble, the sys is controled by the key, and transponder, and the ecm. Most auto locks smiths can come out and check the system, might just need a key re-programed
