1991 Mazda MX-6 starts and it dies within 30 seconds or less.

First take the mass air flow sensor off and clean the small thin wires inside using a non-chlronated brake cleaner then let it dry for 10 minutes then re-install it and see if the problem still exist.If the problem still exist then check the fuel pressure while its running. It should be 30-40 psi if its the 3.8 engine non-superchared and 30-45 for the 5.0 engine.If its not within these specs then replace the fuel pump.

If your car runs while being boosted,you may have an altenater problem, i just had to change mine. it would not charge battery unless the rev's were up at 2000 rpm at idle no charge

distributor module.... any recent tune-ups? e.g= cap,rotor,wires,plugs? parts are reasonably priced and labor should be around 1 hour... start there...

Did you get fuel recently, might have something in fuel e.g water? or even the fuel filter getting clogged.

my mx6 died on me one day,same thing it would keep cranking but would not fire and start towed to a garage spark tested.NO spark changed distributor and problem fixed

fuel pump and or filter is my first guess

Not a solution but i am going through the exact same nightmare and same symptoms with my 1991 mazda b2200. I've apwnt over two grand to have my rebuilt TWICE and my alternator replaced and still does the same thing just starts only to die 2 seconds or so later unless i let it warm up to its max but will still die when taking turns and stopping at lights.

i have a 93 mazda mx6 2.5 the car stall in every gear when i depress the gas pedal in too hard,have to do that gradually in order to ride smooth?

Problem was ECU
