Strange misfire?

Hi thanks for responding,

So, the pump went out and is not working, it does not work at all, it just stopped working randomly and will not work, you cannot hear it prime. This happened awhile after I was trying to solve the misfire problem. So, I’m thinking maybe it was the issue all along. It was cylinder 1 that was misfiring for a long time and then it moved to 2. I tried swapping coils, replacing coils and plugs, checking injectors. Now all of a sudden, the fuel pump just stops working. Before I replace it, I just wanted to know your thoughts. I don’t have a live data scan tool. And the cheap tool I have won’t grab any codes till I turn engine on, as I said, it’s been awhile since I first worked on it, I had to charge battery and was hoping maybe I could grab some codes, but nothing without running the engine, at least with the tool that I have. The fuel pump really does seem suspect to me, what do you think? The 2.7 has a fuel rail and cylinders 1 and 2 are furthest from where the fuel enters the rail, may there wasn’t enough pressure from the pump to send enough fuel as needed? I don’t know, just a thought. I look forward to your response, thanks, God bless.

Hi, sorry it’s been a while. I’ve been very busy. I posted another question last night on here about my truck, now thinking of it I should have just replied to this. Sorry. I checked out relays and fuses and everything seems good. I really think it might be the ECM, I know they don’t go bad often but, the misfire that travelled randomly after a while and now no power to fuel pump, I think that might be it. Any thoughts. All of the stuff I’ve replaced also has no sign of air leaks, and it won’t let me read any codes, it won’t turn on due to no power to fuel pump.

Thanks, how would I go about checking for power, all I have multimeter, I don’t have test light or scan tool.
