Mazda 6 cutout while driving now only fires on cranking

The clue maybe in the push starting.
Check your start position on the ignition switch and don't replace anything else until you have evidenced a fault. It just wastes money and may introduce another fault.

reasons for no spark
cam crank position sensor failure
broken timing belt/chain
immobilizer activated
failure of the ignition control module
run the fault codes to find which has happened.

Before it cuts out does it buck, jerk or skip ?

tune it up n check the timing belt

Hi,

This is likely to be electrical related.

Your vehicle's On-board diagnostic (OBDII) computer will have stored the applicable fault codes.

Have your computer scanned by your local Mazda dealership (or approved agent) for these codes, which will immediately identify the circuit/component causing this condition.

Cheers,

no the bad oxygen sensor never affects misfire it affects only the air/fuel mixture
those are causing misfire (a bad coil, ignition module, distributor pickup, crank sensor,).
and i doubt the crank sensor cuz computer says sensor even if it said to be o2 but no its the crank one its ok if computer fault
i hope my answer was useful

The ecm receives a signal from the crankshaft position sensor and sends timing signals to the ignition control module, whick fires the coil. The problem can be the crank sensor or the control module. The crank sensor is inside the distributor. I have pasted a test procedure below to help you troubleshoot.
1994-95 ACCORD EXCEPT V-6
See Figures 8 and 9
Remove the distributor cap, rotor and the inner cover.Disconnect the wires from the igniter.Check for voltage between the black/yellow wire and ground. Battery voltage should be present with the ignition ON . If voltage is not present, check the black/yellow wire between the ignition switch and the igniter.


Fig. Fig. 8: Terminal identification on engines without VTEC
Check for voltage between the green wire ("BLU 2" on VTEC) and ground. Battery voltage should be present with the ignition ON . If voltage is not present, check the ignition coil and the green ("BLU 2" on VTEC) wire between the ignition coil and the igniter.


Fig. Fig. 9: Terminal identification on VTEC engines
Turn the ignition switch OFF .Check the yellow/green wire between the engine control module and the igniter for continuity. Then check the BLU 1 wire between the tachometer and the igniter for continuity.If the wiring is OK and a problem still exists, the igniter is probably at fault.

Non -vtec engine

Further test showed that the Crank Position Sensor was bad. Replaced it and the vehicle was fine.

Sounds like your fuel pump is going bad. Have your mechanic do a pressure test on it.

the crank shaft sensor is bad, it is heating up, and that is why it works after the water being poured on it, it is cooling it off.....
