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

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

Will the pump run and not build pressure, if you you may have a problem with the pressure regulator. If the pump will not run at all you have a power
supply problem.

92 subaru loyale new distributor and coil still no spark


Had the exact same problem and went through the whole dance. Traced problem to relay under the dash , combination ignition/fuel pump relay. The relay was "clicking" but was internally bad, it would not engage circuit for the ignition. Power was indicated at coil and fuel pump would run but the circuit was not complete through the computer to power the ignition sensor in the distributor. I actually had to "gang" 2- 12 vdc coil automotive relays to replace the original relay. Caution... if you decide to gang 2 relays be sure to separate the two circuits, one relay for ignition, one for fuel pump and tie the coil wires together.

30amp auto shutdown fuse blows is it alternater


The ASD relay supplies battery voltage (12+ volts) to the fuel injectors and ignition coil(s). With certain emissions packages it also supplies 12-volts to the oxygen sensor heating elements. The Fuel Pump Relay is a separate relay controlled by the ASD relay input to the PCM. Fuse #12 (10amp) provides 12 volts to the coil side of both the relays and the ignition switch. Fuse #6 (30 amps) supplies 12 volts to the output side of the relay. Fuse #16 (15 amp) from the relay output to the Oxygen Sensors and Fuse #26 (15 amp) relay output to the PCM. Fuse #24 (20 amp) is Fuel pump relay output to fuel pump. Fuse #19 (10 amp) supplies 12 volts direct to the PCM.
look for burned or melted wires in the offending circuit.
sounds like you wiggled a wire while installing new relay.

No fire to distributor


I'm sure you know the fuel pump won't have any affect on the ignition.
You may need a repair book to get the procedures and wiring diagrams to troubleshoot the ignition system.
I am assuming a new coil came with the replacement distributor. Did the cap and rotor get replaced too ?
Do you have voltage going to the distributor coil ?
Is the rotor turning when the engine is cranked ?

check your spark. If you have spark check your fuel to see if the pump is working. If there's no spark, check your distributor cap. If there's no fuel check your fuel pump relay and also the emergency cutoff switch on the drivers side in the trunk behind the carpet, make sure its pushed in.

No noise from fuel pump when you turn over the car .First thing get voltage at fuel pump relay checked, is there 12 volt to the relay.If no, then problem is again the relay.--------- To reconfirm the problem, try other test, that is remove the relay and by pass the relay terminals with a jumper wire .Then with 12 volt external battery give power to fuel pump connector and see, if the fuel pump starts, then its clear that fuel pump relay is faulty.----------- Also other problem can be fuel pump inertia switch.If the inertia switch is faulty then also fuel pump will not start.-------- The fuel pump relay on a 1995 Ford Explorer is in the power distribution
box, in the engine compartment, driver's side near the firewall.----------
The fuel pump inertia switch is in the right front passenger area
it is below the dash but above the carpet in the right hand corner.--------
Its a push button type inertia switch.
--------
Fuel Pump Activation
When ignition switch is turned to START position, PCM operates fuel pump relay to provide fuel for starting engine. PCM senses engine speed and shuts off fuel pump by opening ground circuit to fuel pump relay when engine stops or engine speed drops to less than 120 RPM. When ignition switch is in ON position, EEC power relay is energized (contacts closed). Power is provided to fuel pump relay and timer in PCM. Fuel pump receives power through fuel pump relay contacts.
Inertia Fuel Shutoff (IFS) Switch
All models use an electrical interrupt switch in fuel system. During a collision or vehicle rollover, electrical contacts within inertia switch open, shutting off fuel supply to electric fuel pump. Fuel supply is interrupted even when engine is running.
A reset button is located on switch assembly. If electrical circuit trips, vehicle will not restart until switch is reset. Fuel system should be inspected before resetting switch.
IFS switch is located under instrument panel, near right side of transmission hump.
----------- If the fuel pump relay, the inertia switch and fuel pump all checked ok, and fuel pump is working with direct 12 volt source to fuel pump.Then problem relates to computer.The computer (power control module, PCM) is faulty and has to be replaced.--------- This will help.Thanks.Helpmech.

Replace a fuel pump on a 1996 cevrolet S-10 4 cylinder


the fuel pump is located inside the fuel tank.

  • Park your Chevy S10 in a safe place with a level surface. Make sure you have enough room to work around the truck.
  • 2 Unplug the fuel pump relay, which is located in the fuse/relay box in the engine compartment on 1995 to 1997 2.2L engine models. Markings on the relay or the back of the fuse box lid should identify the relay. On other models, press the small stem inside the Schrader valve--similar to a bicycle-tire valve--located on the fuel inline rail, right before the first fuel injector. Cover the valve with a shop rag as you depress the stem with a small screwdriver to catch the squirt of fuel.
  • 3 Disconnect the black, negative battery cable and raise the rear of the truck with a floor jack. Safely support it on two jack stands.
  • 4 Drain the fuel tank into an approved container through the filler pipe. Use a hand siphon pump if necessary.
  • 5 Disconnect the clamp from the filler hose at the tank with a screwdriver and remove the hose. Remove the tank shield. Support the fuel tank with a floor jack and a piece of wood on the jack pad to avoid damage to the tank.
  • 6 Remove the tank-holding straps with a ratchet and socket.
  • 7 Lower the fuel tank so you can disconnect the fuel lines from the fuel pump/sending unit assembly on top of the tank. Unplug the pump electrical connector and lower the tank to the floor.
  • 8 Turn the lock-ring tabs holding the pump/sending unit assembly to the tank counterclockwise with a drift punch and a soft hammer until the ring is released.
  • 9 Lift the pump/sending unit assembly off the tank, remove the pump and install the new pump in the pump/sending unit assembly. Discard the pump/sending unit O-ring seal.
  • 10 Install a new pump/sending unit O-ring and set the pump assembly in the tank.
  • 11 Lock the assembly lock ring by turning the ring clockwise until it locks in place.
  • 12 Connect the fuel lines to the to the fuel/sending unit assembly and plug the pump electrical connector.
  • 13 Raise the tank to its mounting position and install the tank-holding straps. Install the tank shield and connect the filler neck to the tank.
  • 14 Lower the truck, plug the fuel-pump relay and connect the black, negative battery cable.
  • 15 Refill the fuel tank, start the engine and check for leaks.

    1997 dodge ram won't start. My fuel pump does not run and coil won't spark. Iv'e checked fuses and relays and they look fine. Could a bad fuel pump cause the asd to kill power to the coil?


    First check any ignition/fuel related fuses. Check to make sure you have 12 volts coming into the pump and coil. If nothing to the fuel pump replace the fuel pump relay - if you do have power to the fuel pump then replace the pump. If nothing is coming to the coil it is either an ignition relay or a wiring issue. If you have 12 volts to the coil but no spark then replace the coil.
    Also the fuel pump/relay would not kill the coil.

    Fuel pump is not working.


    Check the fuel pump fuse and relay. If they are both good then check the voltage at the fuel pump. If you have 12 volts for a few seconds when you turn on the ignition your pump is bad and needs replacing. If you have no voltage the fuse or relay is bad. Be sure and also replace the fuel filter.

    On my 1994 plymouth voyager the 3 wire harness to fuel pump (blue wire) doesn't have 12 volts; should it? fuel pump quit then worked once when hot-wired with 12 volts. fuse and relay is good.


    The wire should not be hot until the relay is triggered. The relay does not get triggered until the ignition key is turned on. It will run for 3-5 seconds or until the system pressure it at max.

    If you are getting spark then it may be a fuel pump problem or fuel pump relay or inline fuse. Always start Fuel system troubleshooting by replacing the fuel filter or filters! You may be able to apply 12 volts from the battery (use a fused line) directly to the 12 volt side of the fuel pump and listen to see if the pump runs. Also may need to check that it is getting a good ground to the fuel pump. Then if the fuel pump does not run independently, replace the fuel pump. The fuel pump relay is computer controlled and several other things give the computer inputs which then controls the voltage to the fuel pump relay.
