I have an 85 with a 22re and I am having a problem with the motor. Cylender 2 and 3 are not fireing, they are getting spark but 1 and 4 are the only ones turning the motor over. Any help?

Thanks ed

 

if the fuel injectors are not firing. all four fire at the same time, trust me on this. down by the ac compressor in the wire hardness, wrap in tape, they is a splice that is common to break. thats your problem.

 

Ok ill try it thanks

 

well i checked all the wire connections and they look good. Now as far as I know there is no fuel filter on the truck. Could the middle 2 fuel injectors be clogged?

 

Ok I found the filter and still no luck! anyone have any ideas?

 

did you check the metal splice in the hardness itself, its wrap with tape so you cant see it.

Ill check them again thaks for the info

 

I have the same problem with cylinders 2 and 3 not firing. Check the splices and they are good. Any other ideas?

 

The only other things I can think of are that the fuel injectors are clogged or there is something wrong with the valves. Im gonna check and clean up the splices more and if that doesnt work im gonna tear it down and check things out.

 

Ok I cut the old splices off and reconnected them and still nothing! Any other ideas???

 

I pulled the wires off cylender 2 ahd put a noid light in it and started the motor and the noid light lit up and blinked as i reved the motor. So that means its the injectors right?

 

Even though the injectors all fire at the same time they ARE on different circuits from the resistor on the wheelwell. Generally 1 & 3 are together and 2 & 4 are together but they may have been switched without affecting the performance. On mine, I couldn't find the break in the wire and ended up running new wires from the resistor to the injectors.

To tell for sure...take a long thin stick or a mechanic's stethoscope and listen to the injectors. They should be clicking when the motor is running. It's sometimes noisy down there so compare the ones that you know are working to the ones in question.
