1993 Mazda MX-5 - Page 3 Questions & Answers
Mx5 wont start the red key light keeps flashing
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
1995 miata 1.80l base model. 179,000 miles. starts consistently and runs well. but in the first minute or so the engine will cut out. restart and cut out again. then all is well.
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
How do you remove the cylinder lock ignition set on a 1994 Mazda Miata
It's almost impossible to do with the ignition lock assy. on the column. Easiest to either drop the column down first, remove the shear-head bolts holding the lock to the column, then drill beside the roll pins and press them out with the lock on the bench. Not for the faint of heart. or locksmith.
