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

if you have spark at the plugs you need to check fuel pressure at reed valve on fuel rail,you will need at least 55psi to fire injectors,

1999 Mazda Miata, engine will not run, sparkplugs has got fire, fuel pump is working good, and it cranks but will not start. What seems to be the problem?


check the regulator on the fuel rain to make sure there is fuel getting to the injectors. also check the relays in the engine relay box on is for the injectors to turn on, there is also a fuse.

I was driving along and the motor just quit I tried to restart, it would crank but not start there is enough fuel, the vehicle is about 10 yrs old


You have two possible areas to check - fuel or electrical systems.

Is fuel getting to the engine? It is possible you have a clogged fuel filter OR a dead fuel pump. To check it, disconnect the fuel line from the injector system at the engine, and have someone "bump" the starter to see if fuel comes out. If it does the pump is working but perhaps not with sufficient pressure to run the engine. Checking that requires special tools, a job for a pro.


Is there ignition spark from the sparkplugs? Try pulling one of the plugs out of the engine, and lay it on the engine block in direct contact with the metal and have someone try to start the engine. If you see a spark jump the gap on the plug, you have spark. If it does work, try each sparkplug, and if there is positive spark on all cylinders it is possible the ignition timing is bad or maladjusted. In this case unless you know what you are doing it is better to have a pro mechanic work on it.

1994 Mazda PU Truck sometimes won't start if shutoff for 5-10 minutes.. Several tries later, it will start. spark seems ok, it gets enough fuel for a second, but then poops out. fuel pump shuto


Well there is no shutoff relay, but there is a fuel pump relay that powers the pump.
I would check it first. The computer grounds the relay for 3 seconds when you crank the engine to boost fuel pressure. Once the engine starts the pump is powered only if you have oil pressure.

Will crank and run fine when engine is cold go for drive come back wont start, new battery1 will turn over just like no fire is getting through1


could be a number of possible faults.1/crank sensor not working when hot,trace this and pour cold water on it(dont do this if it is not by crank pulley as water isnt good for modules etc) and retry.2/sparkplugs worn,but usually they would fault more on cold start.3/fuel pump cuts out when run,try wacking tank from underneath and retry.though I would concentrate on nil spark caused by a faulty ignition module or crank sensor.
Next time it fails to start.pull off a sparkplug lead,make a quick test plug with an old(but working)sparkplug.pull the side wire away from the center electrode 5mm and insert into plug lead.earth ground the plug on its thread against metal on the engine.crank and check for spark visually,don't be tempted to hold the plug while cranking.if nil spark we will have to test further which is faulty sensor.if it sparks ok we will need to test for fuel.
testing for fuel is easy.
when it fails,unclip air filter housing,while engine is being cranked,spray an aerosol based carburettor cleaner into air duct to engine,it should start and run while spraying and stop when you stop spraying if fuel delivery is the fault.fuel pump will then need testing/replacing.
be careful not to spray onto ignition or any areas of spark

All the light work just wont start


Engine is cranking? Check if the fuel pump is working, fuel pressure right and injectors. Check starter and solenoid. Also ignition switch. If all this its OK, then go to sparkplug, coils.

Keep us updated.

Not starting and stumped


Your pump is running but that does not mean it is actually pumping any fuel. If you have no fuel at the filter and the pump is running it is almost certain the pump is not pumping any fuel therefore it is defective.
