20 Most Recent 2012 Mazda MX-5 Miata Questions & Answers

When you turn the key to start, what happens ? Does the engine turn over and not start ? Or does it not do anything ? When you say that the starter seems ok, have you tested it ? Did you jump starter/solenoid and see if the engine turns over ? Are you getting power to the starter when turning the key to the start position ?

The Mazda dealer should be able to help you.

wheel bearing is the first to be check. lift the car on the lift and push/pull the wheels in and out. if excessive play replace the bearings.

Question edited for clarity. Question moved to model category. Yes, you are correct, disconnecting the fuse box has broken the pairing between the key and the immobilizer system. Did you remove the main connection plugs to the fuse box? My thought is that those connectors have never been removed since the car was built and breaking a remaking the connection, you might have some connections that as not as good as they should be. Pull the connectors again and give them a good spray with electrical contact cleaner (that is NOT WD40). Then reconnect. There is various ideas on resetting the Immobilizer here. https://www.google.com/search?q=mazda+miata+immobilizer+system+reset Or a Mobile Auto Locksmith https://www.google.com/search?q=mobile+auto+locksmith+near+me Just for fun, here are the Fuse Box locations and diagrams. They have changed over the years, and as you didn't state the year, here is all of them.

The engine number should be at the back of the engine on the right hand side on a 1.6 liter engine and on the left hand side on 1.8 liter engine. Do expect it to be hard to read. You can also check the right hand side door frame for car details like VIN and engine number.

Question edited for clarity and to remove phone number. This site gets 11 million views a year and some would love to put you on a sales cold calling or India scamming list. Only our sister site www.6ya.com does phone calls. Lots on the Mazda 3, but try there https://www.google.com/search?q=2008+mazda+5+fuel+cut+off+switch+location& ..

You're supposed to take note of what wires go where as well as the length of each prior to removal, or better yet, replace them one by one. If you didn't do that, then you need the firing order diagram, which I am providing below....

1-3-4-2. You can find other specs at https://mossmiata.com/miata-1993.

Try and check the cable that runs to the trunk. the cable may have been worn out and the little metal at the tip of the cable must have been dull or broken or either removed. Specially if there is no more tick sound when you pull the lever.

I just went through this problem myself, I was getting code number 16 (something about BCM/ECU/Immobiliser not communicating) I got it down to the ignition relay in the fuse box under the bonnet being faulty. You can actually swap it with the headlight relay above to test it as they are the same spec. Removing the relay entirely causes the same problem to occur for myself now so I'm 99% sure that was the problem and it wasn't just coincidenceObviously this is just what worked for me but it's something work checking for anyone with the same symptoms

If you have a manual, it will tell you. I will give you a site that has the icons on it. There are several red cars so check it so you can see if one is the one you are seeing. http://www.mazdaoflodi.com/blog/what-do-mazda-dashboard-warning-lights-mean

Sounds like you need a new window regulator, could be the switch, or wiring, get all checked out then you'll have a better idea.

Stick is wrong way round possibly?

Try using some spray lubricant ( WD 40 or the like) on it, there are several joints that are likely a little dry that you can get to when it's about half-way down. It's a good idea to check these and spray every year.

Hi James This could be an easy diagnosis or a real head ache. If you have had this vehicle for some time with no issues and this fault has just occurred as you say in the last 100 miles. I would start with the basics. What has occurred prior to this have you refueled, have you hit any pot holes or any scrapes to the underside of your vehicle? Does this fault occur every time you start the vehicle morning lunchtime evening or just when its damp outside? I would First start with checking fuel quality, low pressure side only I.e feed up from tank. Be careful your dealing with a highly inflammable fuel that will be under pressure. safety precautions need to be taken. An engine fuel feed hose needs to be removed and placed into a clear jar watch closely as the jar fills and make sure a second person turns the ignition off as soon as the jar is 1/3 full do this at the worse time when engine is likely to play up. If it is contaminated (normally water) It will separate after a short period. If there is contamination this would be the first to come through the fuel line hence difficulty when first starting. I would expect there to be a minor amount of water if it runs ok after. See what happens after next refill. If it happens first thing in morning and possibly at night does it get damp outside in your area. If it does and this is when fault occurs it may be electrical check all the high tension circuit. If neither of these ideas work get it into a Garage. My advice would be to take it to a garage if you are not confident with working with fuel under pressure. Good luck

Bad connections, weak battery or a blown main fuse .
