Question about 1997 Mazda 626

1 Answer

1997 Mazda 626 2.0 for ever to start

I have a crazy problem so to make it easy here ya go.
- 15 to 30 minutes of cranking and it will start and run fine
- cylinders will flood out on intial cranking
- fuel pressure is good
-spark is great
- timinmg belt, tension are new and right on
- noticed welding done to the exuast manifold, believe the ECU might be fried because of this.
This is just really funny, because once it starts it runs like a top. But don't shut it off. Almost forgot, no stored or current codes.

Hi,

Would initially suggest that a compression test be performed as well as check for vacuum leak especially on the intake manifold to cylinder head.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

    forgot to mention, perform the compression test on a cold engine.

I have a 1997 Mazda 626 with a 4 cylinder replaced the radiator and when we when to start it all it would do is turn over kind of sluggish it's getting fire fuel in the ground wire is getting hot


Clean ground wire on where it connects to engine block and clean connections on battery. Make sure battery is charged. If battery is low, jump battery with another vehicle and see if it cranks at normal speed and starts.

1997 mazda 626 cranks but wont turn


If you're saying the starter whirls but it doesn't turn the engine, the starter drive is defective or the teeth are stripped on the flywheel. The first it most likely the second is not common.

626 1997 Mazda want crank


Start by making sure you have a good battery, or a good charge on the battery. locate the starter signal wire on the starter , usually the small wire, connect your test light. have a friend turn the key and see if test light lights up. if so, your starters bad, replace the starter and you should be good to go.

Car won't start. The battery and alternator are


If you can jump and start the car then the starter is good.

I had a similar situation where the battery tester showed 13V and green/good LED but I could not start my car. After many tests, I found out that the battery had good Voltage (13V) but not enough Amperage to crank the starter.
I replaced the battery and the car started like a champ!.

- clue to see if you need to replace the battery is if you have used it for
about 3 years or more.
- Dead battery happens a lot more often than bad alternator.

My 94 Mazda 626 quits running while I am driving, but starts right back up. i have replaced egr valve and fuel filter. fuel pump tested out at 40 PSI


Your "crank angle sensor" may be getting to the end of its life: the fault you have described is a common symptom of this failure. The sensor is easy to replace but not cheap to purchase.
