I have replaced the coil and distributor cap.
One could purchase auto parts to repair a Mazda B2000 from the Mazda B2000 Auto Parts online catalog. Other places to purchase auto parts to repair a B2000 would include O'Reilly Auto, Advance Auto Parts and also Auto Parts Wearhouse.
Dirty fuel injectors or spark plugs
plenty of things could be a starter, alternator, ignition switch, bad spark...
I see no reason why a tall person would not fit in a Mazda B2000 because the seat can be slid back. If the person is extra tall, perhaps an extended cab would be best because the seats will slide back further than in a standard cab.
cheap wires
Spark plugs not producing enough spark. Battery doesn't have enough charge. Old fuel.
Idle Sensor might be no good Spark plugs also will cause this....
I have a Mazda 929 (1993) I had the same problem last year...I got a new alternator, and some new wires and spark plugs. Haven't had a problem with it since.
The motor could be frozen up or the motor resistor could be blown. If the motor is frozen and you try to turn it on, most of the time it will blow the resistor which in my 1986 Mazda b2000, is located behind the glove box mounted in the air duct.
.044"-.052" would be fine
Is this with the filler cap off? I once cranked my engine with the valve cover off for just a few seconds. My entire engine bay was a mess with oil. Those rocker arms squirt like crazy.
For the stock XP Iridium spark plugs the gapping is .051, I would suggest not changing the stock spark plugs until your warranty has expired. Mazda tried giving me crap for changing mine.
