MX-3 V6 97 will not start!
MX-3 V6 97 will not start!
1 day my mazda was running on idle outside my garage, i was about to check something so i removed 1 spark plug connector while the engine was running. Suddenly the engine stopped. I connected the connector to the spark plug again and than I tried to start the engine again, but it would not start!. It is only the start-motor who is going around not the motor. After some time i recharged the battery and tried again, no luck, i checked that fuel pump, OK, checked fuses, OK checked 1 plug for spark, OK. What can the problem be?

Re: MX-3 V6 97 will not start!
You checked the fuel pump, how did you do this? Did you attempt to start the car and wait for the pump to prime?PDP wrote:1 day my mazda was running on idle outside my garage, i was about to check something so i removed 1 spark plug connector while the engine was running.

Does the starter click rapidly? Or does the engine attempt to turn over? It's possible it's the distributor, it is a very common problem with these cars. I haven't personally had a problem with it, but there are multiple threads on the forums which describe the problem, causes, and fixes... all in great detail.

Re: MX-3 V6 97 will not start!
Your ECU could be the cause of this. There appears to be a safety feature in the unit that protects it agains some of the stupid things we do. When my engine wouldn't start I simply disconnected the neg on the battery and depressed the brake pedal for 15 secs and this reset the ECU and the engine started fine. In fact I had to do this twice as I did two stupid things the same day. ![Laughing :lol:](./images/smilies/icon_lol.gif)

I know you believe that you understand what you think I said but I'm sure you realize that what you heard is not what I meant.

Re: MX-3 V6 97 will not start!
I disconnected the hose from the fuel pump before it goes into the engine and than tryed to start the car, result was alot of fuel comming:) And it smells fuel when i remove the spark plugs and starts to spin the engine.
The starter clicks rapidly, and the pistons goes up and down. I have now tried to mesaure the primary side and the secoundary side of the coil, and they are OK compared to the design.
What i am not sure about is the resistance of the different high-tension leads. I get one small blue spark from the spark-plugs if i take them out and hold them 5-10mm away from "ground-", but maybe this spark is to little?
What more can i check?
I also tried to remove the -pole on the battery and pressed the break peddal for 15-20secounds, than reconnected the -pole and tried again, no success. Can it be anything else?
What i PCU, ECU?

Re: MX-3 V6 97 will not start!
What you did was EXTREMELY DUMB, and could've resulted in your car being engulfed by flames. There are other ways to check the fuel pump.PDP wrote:I disconnected the hose from the fuel pump before it goes into the engine and than tryed to start the car, result was alot of fuel comming:)
Do what Dan said. Chances are that will solve your problem.

What did Dan say? To disconnect the -pole on the battery and press the break pad down for 15 secounds?

Re: MX-3 V6 97 will not start!
Tried that 2 times, but sadly no sucess:( Any other good tips of what i can do to find out of this? Can it really be bad compression in the engine?

Re: MX-3 V6 97 will not start!
You already know you have fuel. Now, check if you have spark. Take a spark plug lead off, and put the tip of a phillips screwdriver in the connector. Place the shaft of the screwdriver near (about 2-3mm away) a bolt head, and, while NOT TOUCHING ANYWHERE NEAR the screwdriver shaft , have somebody crank up the engine. You should be able to clearly see the spark.

Re: MX-3 V6 97 will not start!
The spark plug wire should spark without anything in it. It should jump from the lead, a half inch to a ground.

Oh! I've never even tried it without the screwdriver... ![Embarassed :oops:](./images/smilies/icon_redface.gif)

Re: MX-3 V6 97 will not start!
I used to have a 2002 s10 xtreme. it was running abit off one day so with the engine on i was wiggleing the plug wires to see if i got a reaction. I did. I blew the coil. The funning thing is that the engine ran perfect after a new coil. lol
Re: MX-3 V6 97 will not start!
I tried all the high-tension leads with a sparkplug in the end 5-10mm away from "ground" and the result was a small yellow spark. What can cause this fault? Is this the fault?

Re: MX-3 V6 97 will not start!
The only issues you can have with a spark is voltage and resistance.
Get a multi meter and check resistance of your wires end to end
You should also be OBDII, do you have a check engine light, or a code reader? If not, well worth $200.

Re: MX-3 V6 97 will not start!
Okei, will go down an mesaure the end to end resistance in all of my 6 high-leads cables tonight. I tried to find out what these values shoudl be, all i coudl find that it should be 16kohm per 1meter cable, is this right?
And i will try to find the diagnose box and try to find out if i have any faults. I guess i can check these without an code reader on my Mazda MX-3 1997 model? Time will show:)
I have no Check engine light visible in my car at this moment:(
