The timing belt tensioner pulley may make a squealing noise from the timing cover area on cold startup. An updated tensioner with a thicker mounting bracket to eliminate vibration may be needed to solve the problem.

1993 Mazda Protege Problems
Misfires under load (acceleration) can be caused by leaky spark plug boots. When a spark plug boot leaks, it allows the spark to arc, or jump, to the cylinder head. New spark plug wires will be needed.
An electrically shorted air flow sensor can cause a crank-no start condition. Diagnosis may show that ignition spark is normal, and there are no trouble codes stored.
A loose or corroded ground terminal on the driver's side of the cylinder head can cause a rough idle, misfires, and there may be trouble codes. Restore the ground to the cylinder head.
If the engine cranks but does not start, and diagnosis shows no fuel pressure, the fuel pump relay is frequently the problem. If the fuel pump relay is defective, the fuel pump will not energize and therefore, not generate fuel pressure so the engine can run.

1993 Mazda Protege Reviews
I bought my 1993 totaled and fixed it....it had 18,000 miles then and has 170,000 now. It has been a trouble free reliable vehicle....it gets 40mpg on the hiway if I drive at 65 mph. Iam looking for another one but they are getting hard to find.....I wish they made new cars now like they did these cars
I bought this car many yaers ago when it it had 120,000 miles on it. It has over 250,000 now. Problems I have had all seem to be the norm, struts, brakes, tie rod ends, CV joints, etc. Over all this has been a very reliable car. No auto transmission issues, engine still runs good, not as strong anymore I'm sure the compression is low, interior when cleaned looks very good. The body has just started to get a couple of rust spots. If my daughter wouldn't have ran it into a guard rail and crushed the front end I would think of getting the engine rebuilt and drive it for another 150,000 miles.
