Next, check that the spark timing is correct and make certain that the compression is up. If the plugs have been connected wrong or the distributor wires have been replaced wrong you may not be able to start the vehicle until that problem is corrected. If the compression is down it could be because the timing belt/chain has slipped. ( don't know which is in the mazda. I haven't worked on one for a long time.)
