93 1.5 injector trouble one not contributing

[2civic]

i have a 93 1.5 injector 2 isn't contributing this is what i did
i pulled #2 injector wire off no change all others about kill under load (foot on brake in drive)
swapped #1 and #2 injector wires problem stayed at #2
pulled plug out to watch plug firing it did
checked valve gap fine
compression same as other cylinders good
timing belt in time
i thought it was injector replaced didn't help (burn money):screwy:

another problem i assume not related it is using 1 qt oil every 400 mi not smoking or no signs of dripping i must be blind

thanks for your help

swapped #1 and #2 injector wires problem stayed at #2

Provide more details about this^ test

i pulled the injector wires off #1 and #2 swapped them and when i restarted it and pulled #1 wire again it about killed it but when i pulled #2 it didn't change
ps i today had car out of gear and raised the rpms to over 2000 and #2 started contributed

why did you swap the wires and not the injectors themselves?

 

[2civic]

i assumed it gave same result and whole lot easier if not explain
it is a new injector i am going to attempt to look at injectors spray out of engine

i sure hope you can help of 3 web sites and 70
views you and one other answering thanks

It makes no sense whatsoever to swap injector wires. Stop improvising tests until you understand how your engine works. Like spark at the plugs, fuel injector pulses are specifically timed for each cylinder.

Have you checked whether each injector clip receives voltage and ground? Remove all 4 injector clips. Touch the power and ground terminals in each clip to the probes of a multimeter set to read DC volts. Does the voltage spike up and down as you crank the engine?

Fixed thanks

i thank you for your help
according to my research injectors all pulse at the same time which i think is stupid but that is what i found i don't claim to be a technician like you


it was a crack in the spark plug wire grounding to the spark plug tube

Post the sources for this^ erroneous research. Then discard.

You stated that injector #2 didn't spray (contribute), but it's clear now that you provided bad information. In the future, supply solid information rather than wild speculation in tech threads.

minis pulling the injector out of the intake while it was running how do you want me to know if it is spraying
i posted non this site to get help no error was intended
i will try to look for that injector firing soon thanks for your help anyway

 

[RonJ]

You did provide bad information because you did no specific tests to show that the injector was not working, contrary to your statement. The truth will set you free.

Remove the injectors with the fuel rail, disconnect the Blk/Yel wire from the coil and igniter unit inside the distributor to disable spark (safety measure), and then crank the engine and observe whether fuel sprays from each injector.

Also do the multimeter test I already mentioned.
