Answer 1

Well it's obvious there is a problem and your dealer does not carry the technicians needed to help you. Your problem is probably intermittent and is the reason they can't find the cause. More than likely a sensor, but there are a lot of possibilities to the cause of your problem. First, when you put your foot to the floor on a fuel injected engine your are not helping it any. You only introducing air and since the computer regulates the fuel through various sensors, it is very unlikely of any kind of "flooding". 2cd, check to see if your "engine light" came on, any reputable shop will have a scanner to read the code/s produced and give insight to the location of a problem. (Autozone scans for free). There are 3 things you can do yourself to make sure all the elements are there to run your engine. You, of course need AIR. Make sure your air ducts are not obstructed, collapsed or otherwise preventing the air from being introduced to the throttlebody. Next, pull a spark plug wire off and connect an old plug to it or even a phillips head screwdriver in it, place it close to a ground (the manifold or bracket made of metal), do not hold it, lay it down in a location easily visible and not in the way of the belts and have someone crank the engine. Check for SPARK. You should be able to see a spark jump at the grounded plugs's electrode or from the metal of the screwdriver to the ground. Make sure the screwdriver is not actually touching any metal tho, you need the gap to see the spark jump. Next you need to check for FUEL. If you are at all familiar with fuel injection you can try this: with the key on and engine off (not running) go to the fuel rail and look for the shraeder port ( it looks like a tire's air valve ), unscrew the cap and press the valve in quickly and stop. F.Injection runs on 20- 35 psi, it will squirt out of the valve rapidly, be careful. Those are the 3 basics needs to make the engine run. These are only some quick and easy tests for the novice, do not rely soley on my information to you, its only meant to give a little help to your situation. If you believe all are there, it could be possible for your TP sensor to be bad or even a crank or cam sensor. Those sensors control the ignition and fuel timing. I would recommend you take it to a diagnostic center near you, not the same dealer. I hope this helps - good luck

Answer 2

If you pumped the gas before you tried to start the engine, you may have flooded the engine. Then when you held the gas open, the motor got more air and finally fired up. If you are not happy with the answer that the Pontiac dealer gave you, then take it to another dealer and see what they say. Good luck.

Answer 3

I am very surprized your pontiac service dept couldn't determine the problem.
I will suggest a couple of possibilities. Have you kept the car serviced as suggested in the owners manual? These cars are very sensitive to fuel filters plugging which means that limited amounts of fuel are able to pass thru the the filter which will starve the engine, also, could possibly be your TCM (throttle control motor) these as time goes by become sluggish especially if your car is driven around town a lot.(Meaning lots of stop and go trips)if its sticking it can be disassembled and cleaned and will work as good as new.
Now--find a good reputable repair shop. They can plug in to your computer and determine whats happening to your car as your computer stores trouble codes. Good luck Jerry

I Would Say You Have Problem With Fuel Take It To Anthoner Dealer.

i could start up with ask your self absorbers or struts, counting on your automobile. in the journey that your automobile has greater suitable than 60-seventy 5,000 miles this could be a sturdy commencing ingredient. Shocks and strut overall performance starts off to circulate to pot after this mileage.

Answer 6

try this, turn on the key and count to 3 then start it, this gives the fuel time to prime. if it doesn't start right away, stop, count to 3 and it should start right up the 2nd time

Answer 7
