    Simmilar, it back fires throught the carb and exaust, and now wont startat all. I have checked the timing chain and it's ok. it's in a 1993 Olds Ciera, 3.3L auto. here's what I wrote to as friend:

    I have a serious problem with the 1993 olds ceira 3.3! replaced a coil pack a couple weeks ago. now it quit on me and sounded like it jumped time, however, when I look at the timing chain it'seems to be ok...loose but ok.

    when it quit I was trying to start and let go of the key prematurely and it did that kick back run-on hiss kinda noise, so then I started it and it would not stay running and had a bunch of pinging and knocking like run on after a car is shut off.

    I really goofed as I didn't check the codes first (but I didn't pull the Bat yet so if I put back together codes should still be there), oh, it also back fired through the carb(injection) and exaust...almost took the mufler and might have plugged the cat. but i don't think so.

    anyway, you know with a back ground with these types of motors so I thought I'd give a yell.

    I guess I don't fully understand the timeing on these types of motors with the c oil packs, anyway any thing you can tell me to trouble shoot would be greatly appreciated.

    Replaced intake valve on 1997 Olds. Bravada, now it won't start. Should I check timing, and how?

    Something has caused the ignition timing to change.

    You didn't list the model year so we have no way of knowing whether your car has a conventional ignition system or not.

That system should be pretty conventional so you need to check ignition timing if you have a light to do it or have a service shop do it. They shouldn't charge much to check it or, as far as that goes, to adjust it if needed.
It doesn't sound like a serious problem and you can check before you go (engine off) to see if the distributor can be moved by trying to rotate it.
You should put some kind of mark to show where it was before you try this since you could otherwise make it worse.

You have to expect though that with almost 30 years 'experience' you may need the distributor and if they are original, perhaps ignition wiring too, replaced.
A rebuilt will do fine; new, they can be costly.

Pull the air cleaner off and crank the engine. If puffs of air come come out of the throttle body when cranking the engine then the timing is not set correctly. Otherwise, after cranking pull a spark plug and see if it is wet with fuel and if so this indicates an ignition problem (coil, distributor/cap/rotor or faulty ECU).

Your vehicle explained it all to you. Take the vehicle in for maintenance. Your car is cutting engine power until your problem is repaired.

Car will not run. push button light is green. car acts like it hits (starter engages and cranks and cuts off). Car has gas(put 2 gallons in to make sure gage is good. Battery is good.I Even tried to...

The 2006 has an engine imobiliser in the ignition and micro chip in the key fob. There could be a low battery in your key fob. Take your spare key or your good key and hold it right beside the push button when cranking. See if that allows the engine to fire and remain on. If so replace the battery inside the fob. You can do this by pulling the glove box (silver) key from the end of the fob and inserting the tip of the key into its slot sideways to pop open the **** shell housing and expose the internal battery.

Car wont start

The problems could be:
1- Check your spark plug. -see any fire come out- " dirty or clean"
2- check the crankshaft sensor - ( you can clean it)
3- check to see the gas go to the fuel injector/caburator line
* If your car use caburator- you may have gas over flood in the cabu. like your father said. IF there is no gas flood- try to spay the cabuator start bottle that you can buy any where in car part store.
I have all three different problems above since I am driven. Good luck.
