Hard starting, FCIM checks out. at a loss
Ever since last winter my trucks been hard starting, started fine no matter what the weather was like before last winter, But this last winter I wanted my truck to warm up faster so I bought a block heater cord and started plugging it in, about halfway through the winter I started noticing my truck getting hard to start, even had to leave it at work a few times because I couldn't plug it in. Convinced the boss to let me plug it in and it started every time so I never messed with it.
This year a about a month ago I starting it and it cranked and cranked then it would fire then die, did that a couple times then started and it sounded like it does when its cold out. was 60* btw. sounded like it was running on only a couple cylinders and loud as ****, puffed some white smoke at first but cleared up (could have been steam idk). Started plugging it in started right up ever since but still runs like **** for a min. or so then clears out and runs good.
Today I had my dad start my truck to let it run, (He starts it about every 3-5 days) A cold front moved into Kansas so it was like 30*-40*, He tried starting it and it did the same thing it did a month ago except it drained the batteries, he charged them back, tried it again, started draining them again so he jumped it with his tacoma and it finally started.
I was convinced it was the fcim so I had my dad with gpas help test the voltage, he said it stayed a constant 48v. Now I dont know what the problem is.... I had him plug my sct in and run the codes and the only code that popped up was a 90261 (#1 injector ckt low). what does that mean btw. Ik that's not the problem because I've never seen that code before and its ran like this for a year now. idk if its relevant but a long time ago my truck through codes for 1,3,5,and 7 something about the injectors but it was running fine so I cleared them and moved on. never threw them again.
Anyone have any Ideas? Glowplugs? I'm a thousand miles away from my truck until Christmas and after I plan on driving it back up here to north dakota so I really need this thing to start because its a lot colder here then in Kansas.
