So this is the story up to this point..
-1992 Nissan 240sx automatic with stock KA24DE
-Car has new battery that is only about 7 months old
Parked my car, in perfect running condition, about 4 months ago. Went to crank it up to go somewhere and it was dead, I grab my other car to jump it off. I get it running but it runs like shit.. We narrowed it down to being the 4th cylinder as that is the only injector we can unplug without it making a bit of difference in the way the engine runs. I've replaced the plugs and I'm still not sure why but I replaced the fuel filter as well.
I hooked up a timing light to each wire including the 4th cylinder's wire and they all make the timing light work, not sure if that can completely rule out the plug wires.. I also tried using another ECU. The first one was out of a '91 automatic that made the engine make a wonderful metal against metal squealing noise, the 2nd was out of a perfectly running '92 automatic that wouldn't even make my car crank. Put my ECU back in and it cranked right up, missing cylinder and all.
We've also tried multiple injectors, the first one ended up ohming out way too high, replaced it with one that was ohming at about an 11 and still made no difference. Not sure if I've missed everything but this is where I'm at, it's been about 4 months since the car has run right and it's been slow going even trying to check it as it decided to do this right before I moved so it's not exactly right outside my front door and with a baby on the way most of my money has to go elsewhere. Any advice on what I could be missing would be much appreciated.
