Okay, I just got done swapping in some new fuel injectors. My #4 cylinder wont fire. How amazingly unsurprised I am, it seems anything I try to do with this car turns into a nightmare. Well, my ignition cable is working, and I swapped out a spark plug, neither seemed to help much. when I first started up the car they all worked fine, but then #4 went out after about 600 feet of driving. These are MSD IGNITION 354cc 2ohm injectors. Any help is appreciated thanks.

 

Do you mean you don't get spark in #4? How do you know it isn't firing?

Is it possible you have an injector problem & your spark is OK? Why don't you suspect a fuel problem - that's what you just worked on...
