Re: Check engine light
Hard to say, those belts are in tight spots, a sensor could have come unplugged, a wire could have accidently been pulled off.
Take it to a garage and have a code scanner put on it to find out why that light is on.It only takes about 30 seconds, and from $60 to a $100. Yeh, that's why I own a scanner.

I have not had a Mazda but in cars I have had it seem to be something which reminds me of timing belt which has slipped a tooth. If your car has a timing belt and has not been changed at the recommended mileage it would be something to check into. Most of my vehicles have been GM and I have had to change 3 timing belt all before 65,000 miles. It never did any damage to my engine but as I understand foreign cars have closer tolerances and can damage valves and pistons. I am sorry I can't be of more help. If your car has not lost any power other than what you have stated it is probably not the timing belt.
By drive belt do you mean the accessory drive belt ? Or are you referring to the timing belt ? A broken accy belt should not cause the car to not start unless the belt slapped around and broke something in the engine area. Check all around and under the front of the engine for damaged wires or wire connections to engine sensors that may have been damaged by the slapping belt. If its the timing belt your talking about then you need a mechanic .
sound like faulty alternator.check battery voltage should be 12.6 volts.replace battery cables if they are very old.if battery and cable okay.start engine check alternator voltage out put at the battery.with engine idling.alternator out put should be 13.5 - 14.5 volts.if not.check alternator, fuse,check alternator battery feed wire and voltage regulator wires for damage or loose connections.check alternator drive belt tension.make sure drive belt not slipping,worn, glazed.replace drive belt if glazed.
With what you changed and the fact that it is a 2004, have you had a tune up in awhile? Little things like a clogged fuel filter or plugged air filter cause this too. Make sure you have no vaccum leaks on your hoses. Visually check the coil wires and make sure they are not damaged. I have seen many problems with fuel pressure to the engine on the 04, mostly hesitation from leaking injectors. That is everything I would check. If you have any more questions, feel free to contact myself or any of our associates. We are here to help you. Thanks for using FixYa. Best wishes.
First things first. The check engine light is blinking because the engine is misfiring to a point that could damage the catalytic converter. If cylinder 4 5 & 6 are all misfiring i would check the engine timing belt for proper installation. These are the cylinders for the left bank of the engine. If the belt has jumped or was installed wrong this would explain the misfires. Unfortunately this is an interference motor which means there is a high probability if the belt is on wrong, the engine valves mat be damaged. I would perform a compression test on those cylinders to verify the belt condition. Hope this helps.
ALTERNATOR DRIVE BELT SLIPPING BELT TENSION NEED ADJUSTING OR DRIVE BELT WORN GLAZED.CHECK ALTERNATOR BATTERY FEED WIRE AND FIELD WIRE FOR LOOSENESS AND DAMAGE.OR THE THE VOLTAGE REGULATOR COULD BE FAULTY.
Check the timing belt. Open the hood and look at the front of the engine and you will see a black plastic cover with10mm bolts holding it on. Remove the 4 bolts at the upper most part and pry back the cover until you can see the camshaft gears. Do you see a belt on them? If not, you will need to install a new belt. I can walk you through the steps if you want to replace it yourself. You will not damage that engine if the belt breaks. I have had mine break twice with no engine damage. Kia timing belts will go up to 60k miles in most cases before breaking or shredding.
it sound to me that possibly the old alternator spiked a surge and might have damaged something in the ECU for the ignition system which shuts the engine and everything down. something heats up over time and then shuts down. try checking the pcm, it might be malfunctioning. oh by the way, does it set off a cel(check engine light)? hope this helps out.
