#28 of 45 mazda cx7 stalled and now will not run by melissa1967

Heres my full story..My 2007 mazda cx7 will crank and run for about a second and then die...cannot tell if any warning lights are on due to the fact it wont stay on long enough. It first started while i was driving it.. I goosed it down a strait a way and it died..so I attemted to restart and it would start for a second to only to die again. It drove pretty good up until that moment, However I have spent 2 grand on a new timing chain and accutator about 3 months ago.. I am really regreting getting this car last year after seeing all the head aches people are having with the 07 models. And to add insult to injury I just bought brand new tires and had the oil changed and air filter changed. The car just didn't appreciate it if anyone has any suggestions please help..I really appreciate it!

I have not been able to solve my problem yet and am not willing to let the mechanics start putting new parts in it, if they don't know for sure. My starting problems only happens after I fill the tank with gas. I tried it with and without the engine running while filling but every time when I try to start it after filling the tank, it acts like it has ran out of gas. The only way to get it to start is by pushing on the gas pedal for about 10 seconds during that time it coughs and sputters. Then it runs just fine until I fill up the tank again.

Well got great news!! A mechanic friend of ours came and looked at our 07 cx7 and it took him 10 minutes to fix the problem. Come to find out..when I had the oil changed they also changed the air filter, the old one had lots of bugs in it.. well what happened was when ran the car fast that day..it blowed a leftover moth into the air flow sensor and blocked the prongs..and therefore was not getting connection..so all he done was blowed out the moth now our car runs and it runs perfect!!! I know if we had of taken it to the dealer they would have charged alot! so greatful to our friend who was so knowledgeable. If anyone is having starting issues you and needs to check your air flow sensor to see if it is bad he said to just unplug it and if the car runs even if it runs rough just as long as it runs..thats the problem.. fortunately we didn't have to buy any parts! I hope this helps.

If the battery is new and you can't even get the car to crank over-- the connections on the battery must be loose or coroded. Check the connections-retighten-and try again.

I'm JUST having this problem myself. Not sure if it's the same.
 
Occasionally, the car just won't start. No "clicking" like a dead batter no nothing. BUT, the radio, lights, etc. all work.
 
I've had it into Mazda (third time today) and they keep telling me there's no problem. They called a while ago and said there's a bad wire somewhere and in certain positions it will cause the car not to start.
 
Previously they checked battery, started, solenoid, connections, etc.
 
Hope they fix it this time, because I'm getting gun shy every time I start the car. I'm afraid of getting stuck again!

Hello Grebor,
 
We are having the same issue when we fill up with gas only then it runs fine. I have not taken it in but seems like something with the fuel pump or maybe when we had the air filter changed at the valvoline oil change place.
 
Did you have any luck locating the problem?

We never did figure out the problem. It doesn't do it all the time, but still sometimes will not start after we fill it up with gas unless you push down on the gas pedel just enought to keep the RPM's up for about 5-10 seconds and then it seems to run fine untill you fill it up with gas again. I have just been living with the problem because I have yet to fine anybody that can tell me, with any amount of certainty, that they can fix it.

Get a new battery. Or at least check the terminals. About 6 months ago, mine started to corrode a lot (on the neg terminal) ... after cleaning it up, it lasted a good 6 months before it corroded over again and wouldnt start. (I had power in the car though...theres just not good enough connection). Cleaned it up Tuesday and then by Saturday it was majorly a mess again. I think there may have been a leak at that terminal. I hear the OEM battery is not that great anyway. Should solve your problem. My Cx-7 starts so much better now! And i'd had the starter, alternator, wires, etc...all checked months ago, and everything was fine. New battery it is.
