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.

When turn key no fuel pump prime. Fuel pump test outside car and find to run ok. I turn the key to on and press the fuel pump relay manually and the fuel pump is running. Fuel pump relay get no power. What should I do?

Engine will start when cold but not after being ran for awhile. Will shut off engine and it will not want to start again for 15-20min. I've fixed all the spark plugs and patched the radiator hose leak. I don't know what else could be causing this problem. It's a 99 Mazda Protege DX

2003 Protege would crank but not start. I figured it was the fuel pump and so I replaced it. It's under the back seat bottom. It wasn't hard to do and it then started right up. Now, one year later, I have the same problem.
My Mazda 1.8 is in a Miata. I have the same symptoms. Any ideas? Where is the fuel pump relay that needs to be changed? Thanks

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.
