Check the diagnostics yourself......black diagnostic box under hood(close to firewall, driverside) use a piece of wire or paper clip and jump it form TEN to GRND!! Turnthe key to the acc position and the code(s) will come up atthe check engine light(longer blinks and faster blinks) let us know what they are they we could help you out more!!

The code is "no G-signal" I think that it has something to do with the distributor!! Could check for bad cap/rotor, plugs, wires??

it blinks 3 times slow waits 6 sec. blinks 3 times slow again-does not blink fast slow fast slow

sounds like problem i had with civic, it turned out to to be cap was cracked, also change your coolant temp sensor, that should help with cold starts

Follow this link & scroll to the bottom for 92 MX-3 Factory Manuals. http://www.books4cars.com/result2.htm?f ... &Submit=Go
Chilton's can get you through some stuff but can't beat the detail in Mazda Factory Shop Manuals. Not cheap but they pay for themselves many times over. If books4cars is more than you can spend, you'll see em on Ebay every so often usually at well under $50. Either the 92 or 93 factory manuals would cover your model.
