    Toyota EFI fuel pump ?

    where are the relays and all the related goodies like fuses etc. that one would need to check if the fuel pump is not working on a 1987 4runner?
    I'm looking at one right now to buy and I want to hear it run before I buy. The fuel pump no worky.
    Any susbstitute cheap ticks to fix the current one by changing just the motor on the pump?
    Any cheap sources for a new pump? The ones I have seen are over $100. Is that what they go for?

    the charlie truck is wired up as a 87 4-runner.. there is a jumper wire under the hood i believe to check the fuel pump. put a piece of wire in there and it fires up.

    find me a stock 83 toyota tank and some beer and ill pull my tank out and trade you.

    i have a computer for a 87 runner also

    no its on the drivers side, there are two little ports... just two wire the meet in a plug but nothing connected to them... stick a wired to close the circuit and the fuel pump should turn on...

    one is the fuel pump and the other is for diagnostic shat... makes the check engine light flash in sequences

    grayson, coops charlie truck had some goofy ass relay that controlled the a/c and the fuel pump. toyota schematics are horrible so you might just want to cut the loom open and look if its that important.
