Have a 97 Mazda, there was no sign of trouble. Ran into the store for 10 minutes then it would not start. Tried a jump and nothing. Get a click from the solenoid and thats it. Been told to try hitting the starter with a hammer and thats my next effort. Any ideas?: Hope someone can help!

93 mazda 626 loses power then dies by kryptonite1976

Hi guys I am also new here and hopefully I can get sum good answeres on my car problems. So it is a 93 mazda 626 4cyl 5spd with 113,000. So a little history on my car. Last year I was having problems with it with the idle air control valve code which ended up being a ghost code, as there was nothing wrong with it. But anyways I bought a used one from ebay and didnt fix the problem, bought a new one from autozone and still didnt work. Bought a good working computer from a junk yard...no go. Then I finally replaced the distributor after much reading and found that the ign system was interanl. Then the car ran great till 2 weeks ago.
 So now to the new problem as this didnt happen when I had ign system problems. I was headed home one day and I noticed my wipers were going slow in the rain then I noticed my tach drop to 0 then back to normal, them my speedometer kept dropping to 0 them back up. Then I noticed all my gauges were dropping and I was loosing power. then the car died and I got to the side of the road. About 20 min later it started back up again and drove 25 miles back home. But while I was sitting there I had no power what so ever as if the alt took a crap and drained my battery. But like I said 20 min later I had all my power again as if nothing was wrong. I am getting a code 34 again for the idle air control valve. I ended up putting in my old computer and drove it 5 miles away and it all happened again lost all power as if my battery went dead. Car wouldnt turn over and no lights or anything again. I just went back out there to try to start it and it acts like my battery is low. So could this just be a simple alt problem, funny tho that waiting 20 min it started back up and had full power when it first happened. I would have thought that it like my other vehicals when the battery is drained from the alt going bad that your not going anywhere. So hopefuly I didnt make this to lengthy or complicated.

I Own a 1998 Mazda 626 lx V6 automatic, I just purchased it 3 months ago in what I thought was great shape.. It has now began to have many different issues. First the check engine light stays on, then the RPM starts to go higher than before going up to 2500-3000 before switching. It felt like it was just delayed a few seconds more then normal. I then took it to mazda ( which of course they would say get a new tranny, but I had to know) and they said the diagnostic was "PO400, EGR system flow malfuntion which may be plugged or open " ..was causing the engine light to stay on and then they only did a drive test and said that I need a new transmission to fix the gear switching issue. Now the brake light has started to come on when I stop, but the brakes are fine. Then I went to start it today and it felt like the starter was toast, (wasn't doing anything).........I tried it a few more times then it worked.....clearly alot of issues....can they all be related to the EGR valve? I really can't think about getting a transmission right now and was wondering if maybe just the filter is clogged or something simple. I am needing some help with winter coming!!! Anyone ????

Well I installed a new alternator and that fixed the problem. It was just weird that the battery wasnt completly drained and I was able to start it after 20 min with no problems. But I drove it a few more times after this and broke down of coarse. And well the battery did eventually get drained at the end before I fixed it. Yup I know I sound dumb, just never had a battery hold juice after an alternator failure like this thing did.
