I want to remove the injectors from my spider assembly for cleaning.
Any advice on how to do it?

It would be so great if we could clean inside.

They seem completely stuck. this is 1998 4x4 blazer s10

they sell them so i know they come out.

 

i got them out with brute force not liking this project

 

If your goal is to clean the inside of the injectors then your best best is an injection cylinder which pushes a concentrated injector cleaner through the injectors while the truck is running through the fuel schrader with the fuel pump off, no disassembly required:



I don't know if the parts stores rent them.

thanks george,

after getting the injectors out, now my problem is that my injectors arent clicking off 9 volts just tried them, anyone else experience this?

ok i got them to open so i could clean inside, im an expert at this point, going to try the reinstall to see if the missfire goes away

 

I have never energized the injectors out of the vehicle so I have no idea what they sound like under those circumstances. The two standard tests for individual injectors are a balance test with a pulse box where you pressurize the lines and then pulse the injector and monitor the pressure drop, looking for balance using a pulse box on each injector ground line. Some scanners can perform this function but I have never tried that approach.

The other test is the resistance of each injector coil.


I realize that the truck has to be put back together for all of this so maybe this is for future reference. I’ll let other members who may have used your 9v battery method comment.

Here is that pulse tester:

thanks again George, I found it needed twelve volts to get them to open
still not sure if they are any good but they are clean at least

 

Can you pressurize the line and look at the spray pattern into a jar?
