The car runs but it's only running on four injectors(drivers side) and the other four on passenger side don't work. I have changed the edu, distributor, fuel regulator, fuel pump, injectors, distributor and still the same, what else can it be. It's an 1989 chevy camaro 5.7 TPI
I have an 1989 chevy camaro and the injectors on passenger side don't work?
I would suspect either a blown fuse.....check the fuse with an ohm meter.......or you could have a wiring issue....if the fuse checks good keep the ohm meter out and star checking for breaks in the wires!!

i would check the relay.
Blame the passenger and get them to fix the problem , thats the way the world now works
If you don't have some one to blame it means you are responsible
It's just the fuel injector fuse for the right bank! LOL
Sounds like you may have an electrical problem, maybe a blown fuse, maybe a problem at the electrical connector going to the passenger side injector bank, or maybe a PCM signal problem to that bank. The TPI injection system is bank fired (aka batch fired) and so it is common for an entire bank of injectors to fail if there is an electrical problem.
First I suggest you check your fuses. They are in the fuse block beneath the instrument panel and they are marked %26quot;INJ 1%26quot; and %26quot;INJ 2.%26quot;
If the fuses are okay then I suggest you unplug the electrical connector going to the passenger side injector bank and use a volt meter to verify that there are 12 volts on one of the two leads on that connector. If there is then next you need to check that the injector driver in the PCM is pulsing a ground to that bank. You should use a fuel injector noid light to do that by inserting its prongs into the electrical connector going to the passenger side injector bank. You can buy a Bosch PFI noid light for $15 or less at most parts stores.
Although a noid light will not tell you the quality of the ground or the width of the pulse it will prove whether or not you are getting a signal to that bank from the PCM. If the noid light is not flashing while the motor is cranking then there is no signal to that bank from the PCM.
If the noid light is flashing and the injectors on that bank are not firing then I suggest you take it to a shop that can test the injector driver function in the PCM by doing a pulse width measurement and testing the ground signal quality from the PCM to that bank using a digital storage oscilloscope.
Hope this helps and I hope you get it figured out.
