1989 Mazda MX-6 sometimes starts other times it doesn't sometimes if you turn key on and off the car starts no rhymn or reason

SOURCE: check engine light Mazda MX-6

Take the car to an autoparts store and have them scan the computer for stored fault codes. The light is to alert you that the computer has noted a fault in one of the car's systems. Most parts stores will do the scan for free and getting the codes will show what faults the computer identified, so you can take appropriate action. Hope this helped and best wishes.

Fcuk I got same problem with my Mazda 3 year 2004. Noone can help me at all !!! Even in Mazda they have no idea where is problem. For me it is at the moment only in cold weather.

SOURCE: First: alarm went off on its own.(mazda 6 2003).

there is often a small back up battery in the immobiliser unit itself, if you can locate this unit and replace the battery with the ignition on / engine running, then it should not need recoding and work fine after that. The other thing that could be wrong is the key battery (if the fob has one) or the transponder chip in the key head. If the key signal is low the immobiliser lamp will light during driving, but this does not explain the alarm going off. That is more likely either a poor vehicle battery, alarm / immobiliser back up battery, or another electrical fault such as water leakage into a tail-light or even the alarm unit itself when it rains. A lot of alarms are voltage sensing and when the vehicle is parked they will alarm if the battery voltage changes for any reason, though not during driving so the battery in the immob is my first choice to look at.

The timing belt has broken. Fortunately though, according to my catalog, this is not an interference engine and the engine should not be damaged internally.
