if you didn't set the timing right, you could be 180 degrees out. Did you align the marks on the cams with the top of the head a TDC on the COMRPESSION stroke?

Lucky for you that the protege motor is not a 'contact' engine. What engine is in it? the 1.6 or the 1.8L? Sounds like you have the timing belt on wrong. Also make sure that the timing teeth on the crank pulley have not been damaged or bent at all.

Suggested Repair

Recheck the timing belt installation rather than resetting the computer. Align the cam marks with the top of the head at TDC on the compression stroke so the engine is not 180 degrees out, and inspect the crank pulley timing teeth for damage or bending. Confirm whether the engine is a 1.6L or 1.8L.

Conversation Summary

The owner of a 1999 Mazda Protege says the car has spark and fuel after a timing belt replacement but still will not start, and suspects the computer shut the engine down. The fuel pump does not run with the key on, although the relays are good. Experts say the timing belt may be installed incorrectly or 180 degrees out and advise verifying cam alignment at TDC on the compression stroke and checking the crank pulley timing teeth.
