7.3 not running!
So heres the problem. Its been cold here for a few weeks now, lately been getting down into the teens, and even single digits. When I last fueled up (about a week ago) only put a half tank in. I didn't put the dieselkleen additive in (blew it off because it was starting fine lol) I sometimes plug it in, sometimes not it depends where I end up parking when I get home.. Either way plugging it in usually helps but now nothing. Anyways, I went to start it yesterday morning with a little bit less than 1/4 tank and it was plugged in. Started up fine, let it idle for about a minute (late for school haha) Took off, went down the end of my road and around the corner, stepped on it alittle to get up a hill and it kind of lost power and started loping, shut off. I let the GP's warm back up and tried again. It loped for about a minute straight and i tried keeping it at 1000rpms, warm it up a little bit more and it finally started running fine and by the time I got to school it was up to temp and running perfect.
Now, when I left school It was of course cold, started fine and then the exact same thing happened. So I poured about an OZ of the dieselkleen in the tank and got it to idle some how, eventually warmed up and I got home. Started it a few times when I was home and it was normal, fired up no problems. Eventually went out and filled the tank up and put the dieselkleen in.
This morning I went to start it, not plugged in. Cranked and got nothing. Waited for plugs to warm up a few more times. Fired up and idled for a few seconds, then started loping and died. Tried a few times and said F it and took my dads chevy to school. Got home and tried again.. same exact thing happened. It will fire after cranking for a while and run really rough, sometimes idle normal and then eventually die. I pulled the fuel filter out to check if it was gelled inside there (recent filter) and it was not. I tried the trick of putting cables from the positive terminal on the battery to the GPR, and it didn't do anything..
I'm thinking that its either gelled fuel or GPR/GP's.. What else could it be? Its been just plain cold here lately and it's been starting and running absolutely fine until these two incidents.
Anyone got any pointers..? Thanks
