I've already spent over 200 dollars on a fuel pump that I just found out I don't need....the old one is working fine, but I am still not getting gas to the engine and cannot get the car to start....Does anyone know where the relay switch is or what else could possibly be wrong? Thanks for anyone that can help.....I'm going to lose my job if I can't get this fixed soon.

Thanks,
Trish

What to check next

Diagnostic guidance. Suggested checks and possible repairs are separate from the owner's reported results.

Document which ground connection was repaired. If the fault returns, have the relevant circuit checked under load before replacing another pump or control component.

I am not an expert but had similar problem with my maxima. First it was the fuel injection system. Had to replace a part.

And 2nd time it was due to the Distributor cap. Distrubutor cap was cracked . Car was cranking but no spark was generating. Hopefully it helps

Why do you say it's not getting fuel? Take the fuel filter to engine hose off, have a friend crank the engine, if you see fuel coming out then its probably the pressure regulator has taken a dive. If that's the case try back flushing it with Berrymans carb cleaner. If it still doesn't start try replacing the regulator. But its an expensive part $100+. Post your results.

Discussion summary

The owner of a 1990 Mazda 626 2.2 reported a no-start believed to involve missing fuel delivery after an apparently unnecessary fuel-pump replacement. The final update attributed the problem to an improper ground.

Reported outcome: The owner reported that the problem was fixed after the grounding issue was addressed.

The exact ground and test results were not supplied. The reply suggesting cranking with an open fuel hose is not a recommended test.
