check your entire ignition system especially the ignition control module

understand this is only a estimate, base on you have all the tools and parts. If this is your first, you are looking at approxmiately 8 hours. no include testing and readjust.

DO YOU HAVE 12 VOLTS ON INJECTOR WIRE ON ONE SIDE WITH KEY ON? IF SO ARE YOU GETTING SPARK? IF YOU HAVE NEITHER YOU MAY NEED A NEW CRANK SENSOR. VERY COMMON ON THIS ENGINE WHEN THERE IS A LOSS OF SPARK AND INJECTOR PULSE. INJECTOR PULSE(GROUND SIDE)IS CONTROLLED BY THE COMPUTER. IF YOU HAVE SPARK BUT NO INJECTOR PULSE AND 12 VOLTS ON INJECTOR FEED WIRE YOU MAY HAVE A FAUTY ECM(ENGINE COMPUTER)

SOURCE: fuel injectors spraying to much gas

to be honest, with an 89, all you can do is replace the injector. how an injector works is there is a small amount of current that is run to a coil around a rod (if you are unaware, this produces magnetic fields). the magnetic field produced pulls up what is usually a small ball, allowing fuel to go through the tip of the injector nozzle. all you can do to fix this is to buy different injectors.

just a question..why do you think they are spraying too much fuel? because it may just be that you have excessive fuel pressure and your fuel pressure regulator is bad. hit me back.

Sounds like a bad fuel pump.
