SOURCE: 1996 mazda mx6 ls cranks but won't start

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: Where can I find free

cannot find fuel pump circuit, but here is engine. I assume fuel pump will come off the "Run" wire shown below branching below the Ignition Switch that says "To Fuse Block." The fuse block will have a fuse and/or relay for the pump and will then have a wire from the fuse box to the pump. OK?

Start and die


Go to Autozone.com site and register your vehicle so you can get a free wiring and fusebox diagram.

I have several things to contribute. The keyswitch has 2 terminals which supply energy to the spark system. The START side of the keyswitch and the RUN side both energize the Relays in the Powerbox.

Without knowing how long the truck runs with your problem at each start, I am estimating it could be getting power only while spinning the starter. The engine catches and then dies when the key is released to RUN position.

Looking at your wiring diagram find your power wire from the Ignition key and see if the power is coming off the ignition switch in RUN. If you have power from the Key, then you need to look at the Relays.

Check your fuel pressure to see if the Fuelpump relay kicked out or see if the Ignition relay kicked out power to the ECM. The wiring diagram should help and Fusebox diagrams are available as well.

I hope my info is helpful, please rate my info.

Elecric fuel pump wiring diagram needed - fuel pump not working...new relay didn't help


turn the ignition key to the ON position without starting the engine up. You should hear the fuel pump run for 5 seconds. If not heard replace the oil pressure sensor which is linked to the same circuit.When oil pressure is acheived the fuel pump relay takes over to run the pump

If it runs on start fluid and nothing else its obviously a fuel concern fuel pump ,fuel pump relay ,check fuel pressure at the regulator that you replaced.

No Power to Fuel pump


I would check the ground for the fuel pump relay that operates the switch side of the relay.
You should have 2 12v inputs to the relay. When the relay gets 12v input, it closes the relay switch on the heavy current side that sends 12v to the fuel pump.

A relay is needed because you don't want heavy current going through the switch.

Also, most cars only run the fuel pump for 2 seconds when the key is turned on because you don't want the fuel pump running without the car running. If you listen closely at the fuel tank, you should hear the pump run for 2 seconds when you turn the key to "ON"
When the key is turned to "START", the fuel pump should run continuously.
The engine computer tells the fuel pump to shut off if the engine rpms are zero.
So, I would check the switch side of the relay. Power amd ground.

No power to fuel pump or to pump fuse at fuse block


You can get wiring diagrams from autozone.com -- they have parts of repair manuals online. I have the smae problem but the person I got my 88 fox gl from wired up a switch going to the fuel pump that you have to leave on while driving. I"m probably giong to fix this soon. It looks like the wire powering the fuel pump relay comes from the ignition switch. So if the pump side of the relay is good, but aren't getting power, you may want to see if your ignition switch isn't providing power on one wire, going to the fuel pump relay.
