need help with fuel injection?

Question

I have a 1995 geo tracker one day it just died i have checked everything that i know to it has fuel to it and out the return line but the throttle body stays dry the injector is not firing i was told it sounded like the computer went out but a local salvage yard has loaned me 2 different computers to try and it did the same with both it doesnt seem to be getting any power to the injector i have found no blown fuses or broken wires i would really like to get it fixed before i have to take it to the shop and pay someone to do it

Answer 1

i would check out your ignition control module...

it controls the timing of the injectors and weather or not it fires....

Answer 2

OK
When you turn on the key do you hear the pump come on and shut off. If not Check the inertia switch or fuel cutoff switch. There is a reset button on it.
If you do hear it go under the hood and on the fuel rail you will see a check valve to attach a pressure gauge to. press the valve like you would a bicycle inner tube to release just a bit of fuel....Does it escape under pressure or dribble
Under pressure - you have injector wiring issues
dribble - fuel filter or fuel pump issues. These should get you going in the right direction

Answer 3

Maybe you have a clogged fuel filter. You could use an electric tester and make sure you are getting electric current to the injectors. Make sure not to use any extra current to force the system and over power the computer.

Answer 4

Have you taken the throttle body injector out and apart,,and cleaned the screen out yet???
have you tested to power to the injector head???
TPS sensor???

Answer 5

have you checked the wiring harness from the computer? or from the power supply?

see if you can get a voltage reading from the power supply or signal from the comp.

hope this helps

Answer 6

its the ignition control moduel.it controls spark and the fuel injecters. change it out and it will live again.
