1984 toyota pickup 22re fuel injection is not getting fuel to the cylinders


Most likely a fuel pump problem, locate the diagnostic check connector under the hood and turn the key on then put a jumper wire between the terminals FP and B+ if it start then the fuel pump is ok and the problem may be the EFI relay or efi fuse

Im working on a 1986 toyota pickup 2.4l efi non turbo 4x4 i replaced the head gasket and i have a black wire coming from the intake wiring harness that has no plug on it .if i touch this wire to a hot wire...


Sounds like this wire should operate the electric fuel pump through the fuel pump relay.The fuel pump relay should start the fuel pump to maintain fuel supply to the common fuel rail and any surplus fuel will be bleed back to tank by pressure control.The injector opening sequence is contolled by computer once the engine is properly timed.
If you say the engine runs for a few seconds it would indicate fuel pump or relay is not getting power to operate or fuel pump is not delivering enough pressure to feed the injectors

1986 Toyota rv fuel pump issues. Changed fuel pump still not not getting fuel. Can pour gas into efi and it will start could it be bad fuel pump solenoid? Where would I find that solenoid?


When you turn the key to start it, do you hear the fuel pump whine as it begins to prime the system?
if not then your pump is not getting power, it could be a fuse, a relay, or the cut off, which will kill the fuel pump if it senses force powerful enough to be a collision. Also you may want to replace your fuel filter, it could be clogged and not allowing fuel to get to the engine fast enough or with enough psi.

Hard to start


Fuel pump is a possible cause but I would check the ignition timing first.
