you may need to run a wire from a keyed ignition source that has power while cranking and running to the fuel pump relay and bypass the pcm to test wether it will run, if it runs put a more permanent wire in place.Not too sure what tests youve done but it seems that fuel is what your focusing on so a quick test is too spray engine start up the intake tube to see if the engine trys to run if it does it eliminates a lot of other potential reasons for a no start condition.Also try squeezing the fuel return line to see if the added pressure will try to make engine run.Could be time to replace fuel pump etc anyway let me know how it goes good luck with it

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

SOURCE: mazda b2300 electric fuel pump no working

pumps are rare to fail on these. the quick easy thing to check is the inertia switch. if in a wreck or jarred hard, this switch shuts down the fuel pump to stop a fire and must be manually reset. it is located behind the lower kick panel on the passenger side of cab interior. its a little black switch with a red button facing upward. if tripped the button is up. push back down and it will re-engauge. try to start may have to crank alittle to prime. this procedure is in your owners manual too if need be.

WE PUT NEW FUEL PUMP ON B2300 MAZDA 1994 YOU PUT GAS IN THE THROTTLE AND IT RUNS BUT WILL NOT START NO OTHER WAY


New pump may be bad--it happens. There should be a check valve that keeps fuel from draining back when you turn it off. If this is not working it could cause this.

Replace fuel pump in mazda truck B2300 1996


I have seen when the fuel pump goes out, it will suck.junk up in the lines and.clog the fuel filter, so maybe.try changing that first.

did you plug.all the.wires back into.the.new.fuel pump,.do you hear the.fuel pump run when you turn your key.to the on position? now if you push your gas pedal to the.floor this will stop the.fuel from being pumped, have you checked to.see if you have fuel pressure in the.fuel rails, by either a fuel gauge, or be pressing in the Schrader valve ?\'

I replaced the turn signal switch and now it wont start. i can hear the fuel pump kick on. makes no sense


You said you hear the pump come on, then said fuel pump not running ???
Check the fuse for the pump, preferably with a test light to verify power is there. Key must be in on position. If the fuse is powered, feel for the fuel pump relay to click when you turn key to on. Put your finger on it while someone turns key to on. If it clicks, check for power at the tank connector on the pump wire, while the engine is cranked. If power there when cranking, the pump must have failed and needs replacing. If the relay clicked with key on, and no power at the pump wire at tank while cranking, then check wiring from relay to pump connector-the fuel wire may have broken.
If the relay doesn't click when key turned on, check for the power feed for the pump at the relay terminal. If the relay has power available to be transmitted to pump, then the relay's signal from the computer or the ground side of the relay's coil signal (from the computer) may need checked.
If the pump is working, and you have good pressure in the lines, check the injector circuit. Also a fused circuit, so check the fuse first. The injector should have a steady voltage signal to it with key on. The injector only has two wires, the power wire and the ground wire which goes to the computer. When the computer momentarily grounds the injector circuit, the injector "pulses", causing fuel to spray out the bottom.

1994 mazda b2300 turns over fine but won't start not getting fuel, i do not hear fuel pump when i turn key


There is a fuel pump "roll over" valve in the floorboard on the passenger side. It stops the fuel pump from running incase you roll the vehicle to prevent a fire. Check that the switch didn't trip from someone possibly kicking it or something. Then check any fuses or relays (swap relays if you have a spare or switch with the same on in a different slot). If everything checks out ok, then you probably need a fuel pump

My 96 blazer wont start it just cranks but wont start?


A typical engine needs mostly just gas and spark to run (besides air of course)
Sounds like the engine is not getting one or the other.

Fuel goes from fuel pump, to filter, to fuel pressure regulator, to fuel rail, to injectors.
You can test for fuel pressure with key on, at the fuel rail. There will be a test port on the rail that you can put a rag on top and push in the valve to see if there is pressure. (or use pressure tester)
If there is no pressure, check that fuel pump relay is working. (you can use an ohmmeter on relay to see if there is resistance). You can also test power to relay and to the pump with a voltmeter to see if pump is getting power. Or turn key to ON position and listen to see if you hear the pump turn on.

If you have no spark to any cylcinders, the crank shaft position sensor may be faulty which is very common in GM vehicles.

You can use an ohmmeter to test the sensor itself.
You can also get a spark plug tester to see if there is spark to each cylinder.
You can also remove one spark plug, plug back into plug wire, lay on top of engine so spark plug diode is 1/4" away from metal surface. Have someone else turn engine over while you look for spark. Do this to each cylinder.

Car wont turn over when started


When you turn the key to full electrical power (right before you'd crank it), do you hear a hum from behind you? It'd be the fuel pump, and it should run for a few seconds. If it does, and you have no cranking when you turn the key, check the starter relay - if it's shot, it won't allow power to the starter, and the car won't crank. If you don't hear the hum, check fuses and relays for the fuel pump first, and if they're OK, you may have a dead fuel pump.

1996 silverado 5.7 vortec cranks but wont start. fuel pump, gauges, "idiot" lights, blinkers do not work. flashers and all the rest of lights operate. Just replaced coil and this happens


Had the same problem with my '96 Silverado with 350 Vortec. The truck would only crank. It would start if fuel was poured down the throttle body. Could not hear the fuel pump hum. Fuse was good, but could not hear relay click. Relay was good, Did some electrical wiring trouble shooting. Turned out that one of the connectors that clasp onto one of the pins of the fuel pump relay wasn't making a good connection, too loose. I just stuck a peice of wire into the connector and pushed the relay back in. Relay clicked, Truck Started. It's been more than 4 yrs. since I made that McGuyver fix. Still firing.
