1990 Mazda Protege ProblemsCrank but No Start Condition
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.
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.
