This is usually a 10 amp fuse located under the driver side dash. If it is not this it should be a relay located above the fuse box.

89 tracker 5 speed 4x4 will not run motor cranks,has fuel pressure,plugs are firing,will run if gas is poured in throttle body.injector is not pulsing.no voltage going to injector.checked wires all way to...


Check the oil. A few of them cars back in the 80's had a low oil switch to prevent the engine from running if the oil was low by turning off the fuel pump. But if it runs when you pour gas in it, and you say it has fuel pressure? Why is it not getting fuel? There has to be shut off somewhere in the line that is preventing it. Try removing a battery terminal to kill the entire system then, retry it. You never know.

Is it possible that the computer on my 92 geo tracker is what's keeping it from starting???? will the engine turn but no strat????


turn the key to acc mode and if the check engine light is on then the computer is working. check for spark. listen for the fuel pump to turn on its in the back passenger side if both those work and you didnt mess with distributor plugs rotor or cap then you may have to bypass it. or the fuel injector could be clogged. take off the metal air intake to get to the fuel injector and pour a little gas directaly in and see if it starts. if fuel pump spark and pouring gas into were the fuel injector is then it might be a bad fuel injector or it needs to be bypassed.
