  • Fuel pump runs instead of starter wtf

    When you turn the key the fuel pump runs instead of the starter, same when you jump thee terminals on the solenoid. Also when the key is on the injectors run, what in the name of ¥£€¥ is going on?

    What has been / being done to the car ? If this is a random failure I would suggest ground issue . Back feeding the system ?
    New build on the way .

      Just put the motor in, ive checked the grounds, though it is possible I've missed something, I compared all the wiring to a running car

        Man, that sounds implausible from my understanding of the wiring. The one thing that connects them both I can think of is the ignition switch.

        I thought computer, but it doesn't switch the fuel pump, the VAF does.

          I know! You'd think arcing the the solenoid would at least run the starter, i am flat out stumped... As well as frusterated

            is it missing a fuse or are one of the wires spliced wrong?

              Fuses look good, as does wiring, compared with the car next to it

                Just for fun I'd try a remote starter switch. That just connects two terminals on the starter.

                  How do you know when you turn the key if the injectors are working? They won't do anything unless the engine is turning, because the have no signal.

                  Im trying to figure this out.

                  Was anything else done, besides swapping the engine?

                    there is a hum from the throttle body, maybe its not related? I've never noticed it on any other one anyway, I just assumed it was injectors but probably isnt. Nothing else was dont to speak of, all the parts came the original motor itself, only the basic long block of the motor was used from the donor car, no intake, distributor ect. Shadetree has been working with me on it over the phone but I can put power to the starter any which way, even a direct jumper wire from the battery and all that happens is the fuel pump runs for as long as I supply power.

                      Hum is probably the fuel flowing through the rail and back to the tank. The injectors would be a pulsing sound.

                      This is weird.
                      Any difference that makes no difference is no difference.

                        Pull the main fusible links (replace w/ long leg cartridge fuses later). Then try to jump the starter with a screwdriver or fancy alligator clip remote start button. Maybe the starter solenoid wire is back feeding the system somehow.

                          I did try swaping them all out with jumper wires with no luck, I immediately assumed it was in that block as well, unless its the block itself, the fuse links are not. I am going to put a differnt starter in it tonight, even if its not in the starter that is an easy way to eliminate that as an issue, just to narrow it down a little bit, if it does happen to be the starter that is the strangest starter failure I have ever encountered

                            Is it possible you reversed polarity at the battery?

                              Was the starter! Although now the thing won't accept fuel:banghead: will run on carb cleaner AND has fuel at the rail but won't run off of it
