SOURCE: Do you know where or if a 2000 Mazda 626 has a

Hello, I am going to make a few assumptions here. The vehicle has an electric fuel pump and you replaced it. The vehicle has fuel injection. The engine is actually cranking, just not starting, when you say "car still won't crank". You are getting fire to the spark plugs at the plug ends. You checked the fuel pump for power at the pump. No power, then you back traced the wire to the fuse block and checked the fuse to see if it was blown. If the fuse is good back trace the power to the ignition switch and/or ECM for power. You have power at the pump, check the ground and make sure it is connected properly. Will the pump run when someone turns the key on? Pump runs, check fuel manifold for pressure. No pressure, check the fuel filter for blockage, or replace it. Fuel pump doesn't run, new replacement pump is defective. There is usually some type of control module for the fuel pump on fuel injected vehicles. Good Luck, RAC

You might want to check the ECU. It is common for this model to have a blown capacitor. It is in the passenger side kick panel. It is common for this model to have a this problem. I had mine repaired.

Faulty fuel pump or fuel pump relay. Locate the fuel pump relay. Remove it. And turn the key on again. Check if fuse is holding.

I have a 1993 mazda b2600i. The fuel pump randomly shuts off. Repaced fuel pump shut off relay lines cleaned tank. Once it shuts off cant even get it turn on when bypassing fuel cutoff relay.


There is a chance that your pump itself is going bad. Just like a starter that is on its way out. if you tap on it sometimes the brushes will make contact enough for it to go ahead and start, a fuel pump motor has brushes and an armature. Sometimes they will not make contact and work, then other times they can run fine for a bit.

Where is the fuel shut off switch located on a 91 isuzu rodeo v6


This vehicle does NOT have a fuel intertia cutoff switch like Ford vehicles. As a safety shutoff, it uses the oil pressure switch. If the engine stops and loses oil pressure, the oilpressure switch cuts off the fuel pump power. There is NO reset on this vehicle
