02 Chrysler Voyager engine misfire?

There is a misfire in the engine and a check engine light for a 02 Chrysler Voyager 3.3L engine. The code came out injector1. Replaced the ECM first and it stopped the miss. The next day started it up and it was misfiring again. So I replaced the fuel injectors. Fired it up and misfire. What I noticed was the two wires going from the injector to the ECM were positive. Usually it's one wire positive and the other negative. Frustration has gotten me here hehe. Any suggestions on what I should check next? Thank you!!

check the fuel pressure as low pressure will cause this code. ppressure shold be 53-63 psi but you need a scan tool to activate pump to do it correctly.
