dead cylinder

[5.0Anthony]

I have an 88 gt 5.0 ho. when i got it it had two dead cylinders. the front two drivers side. i have done almost everything and i still cant get the second one to work. I changed the injectors in both the one started to work and the other still nothing. I have run out of things to try so if you could help me great

Dead??? Have you done compression check? What all have you tried. Could be many things. Let me know what you have tried and I can give you some ideas.

I have done a compression test. it is 123 psi. there is spark. i have put a noide light on it and it lit up like it was supposed to. the spark plug looks brand new still. i have aslo changed plugs and wires.

have you verified the injector is firing correctly? like move it to a different bank and see if the problem follows?

The signs that i am seeing of it not fireing is the new chrome header i put on is not turning blue or gold like the rest are and i can hear it and feel is missing in the exhaust. so how am i supposed to know if the injector isn't firing on a different bank?

Pull the plug wire off, does the car still run the same or does it idle rougher? Old fashion way of finding out. Using the Chrome Color changing isn't the most accurate way of telling. Mine still look new and have 1K miles on them.
