Question about 1991 Mazda B-Series
Posted by Anonymous on
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

yes it isn't that much if you buy them.they slide inside the coupler and release the line.

are there any fault codes present? i was looking at the fuel injection diagram on autozone.com and the only thing i can see that controls injector pulse width is the pcm. are all the injectors open for 15ms? you should also check fuel pressure. if you want to look at the diagram, go to autozone.com. register and enter you car. select repair guides, chassis electrical and the wiring diagrams

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.
