Ok guys I am new to forum posts so bear with me, I have a 90 accord with the f22 and it has a rough running problem, the injectors seem to be testing ok the compression checks out within specs and I have spark but when I pull off cyl 1 and 2 plug wires there is no change in the way it runs. It's only running in cyl 3 and 4 that I can tell and I'm kinda leaning towards the fuel pump, but any suggestions on what to do or anyone's experiences would be greatly appreciated ! Thanks!

 

What compression readings are you getting?

How did you check the injectors?

 

Compression is consistently 170 on each cylinder and I checked the key on voltage on each plug to the injectors,and checked the resistance of each injector,all were the same.

 

A resistance test on the injectors doesn't rule them out. Probably the easiest way to rule out injectors is to switch them with a good cylinder and see if the power balance test results are the same.

I wouldn't jump to the fuel pump until you do a fuel pressure test. Your accord has an access port on the rail. You may be able to get a loaner tool from a parts store with the proper adapter.
