Turns Over but Won't Start
Hi all,
Drove my *automatic* '95 for an hour to a store, parked it, went shopping for an hour, came out, and the Miata would not start. It happily cranks but does not start. Noticed that the 'hold' light on the dash blinks continuously (this is an automatic) and believe that it is trying to tell me something. Have seen the hold light lit when turning the key to start the car but never saw it blink before. There is no mention of an error code for a blinking 'hold' light, neither online or in Rod's manual. I get the impression that there may be some failed relay that is restricting spark, perhaps 'thinking' that the car is not in Park. I moved the shifter about rigorously, exercised the hold button, giggled the key in the solid feeling ignition, but no joy. Any idea what it might likely be? There is some talk about a EMI (?) relay, and a 'main' relay that can go bad unexpectantly and have the symptom of cranking without starting. If that sounds like the likely cause can someone please tell me where this relay is located (in fuse box under hood, or under dash) and what the part number is? Or if you have some other idea what the problem might be I would greatly appreciate your advice. Thanks in advance for your thoughts or suggestions. Regards, |

Continuing to drive your Mazda in this condition could cause damage to your transmission." But it doesn't say it should not start... so I wonder if they are talking about the hold light blinking while the engine is running or car is driving, and that the blinking hold light might mean something else when the engine is off. Any thoughts on this? Thanks! |

Don't have any suspension, rollbar or top issues, do you? :-) If you haven't already done so, it would probably be best to post this question on the moderated, (ugh, I hate that word), forum on Miata.net. Someone there should have some suggestions for you. This group is seriously down to like 10 people or less that post regularly, so it is becoming a poor source in general for Miata technical advice. 8 years ago, almost any question asked was answered within the hour, although sometimes by Leon, which didn't really count. ;-). Ahhh, the good old days......... Pat |

Pat, don't forget it's quality, not quantity (of posters) ;-)
My thought would be; your timing belt may have snapped. It's a long shot but worth mentioning. I think you can have someone watch thru the oil filler cap (while cranking the starter) to see if the valve train is operating. Good luck, there's few and far between automatics so, if it's related to that, might be a bit more elusive.

Thanks for your input Chris. I had that thought too.. but the timming belt
was done about 25k ago, so it seems unlikely. Will let you all know what the mechanic says. It would seem logical that the flashing hold light would be some sort of error code related to the transmission... like it does not 'think' it is in Park, or the pringle switch on the transmission is bad (if this model has such a thing)... to be continued.

Agreed, but as already mentioned there aren't too many automatic owners here and I'm guessing the electronics are different? Can you get any help from Google? I found this on Miata.net: ================================================== ================ The HOLD light flashes a code similar to the Check Engine Light. You can cancel the codes from memory by removing the negative battery cable for at least 20 seconds and pressing the brake pedal. You might want to try doing that first. To pull the code, connect the TAT and GND terminals in the data link connector with a jumper. Turn on the ignition, and the transmission control module flashes the Hold light with the code. The codes are 2- digit and are as follows for the 95 (I assume the 94 is the same): 06 - Vehicle speed sensor or circuit 12 - Throttle position sensor or circuit 55 - Input/turbine speed sensor or circuit 60 - Shift solenoid A or circuit 61 - Shift solenoid B or circuit 62 - Shift solenoid C or circuit 63 - Torque converter clutch control solenoid valve or circuit 62 - 3-2 control solenoid valve or circuit ================================================== =========== Here is whe http://forum.miata.net/vb/showthread.php?t=267081 -- XS11E, Killing all posts from Google Groups The Usenet Improvement Project: http://improve-usenet.org |

Thanks XSE11. How did you find that? I searched and searched and only
found talk of a flashing hold light while driving and nothing more. Sadly I didn't watch the flashing hold light long enough to distinguish a code pattern, just saw it as continuous blinking. It is at the shop and connected to their computer... will know the results soon. Thanks again.

I was searching with 'flashing' not 'flashes'.... but as it turns out the light continiously blinked, no pattern to represent a code. The main relay was replaced, and that made the flashing and other lights appear normal again, but it still would not start. The coil pak registered just 1v instead of 12v and so that was then replaced. Now things seem good again. But no explanation as to what may have cause this failure. Thanks everyone for you input. I appreciate all the help on this and from the group in general. Regards, |

Did your tach vary erratically before the non-startage? The first sign of poor grounds is the tach; the final sign is coil pack failure. -- Lanny Chambers St. Louis, MO '94C |
