So i left my truck sit in 5-15 degree temps for about 3 days and now i can not get it to start for the life of me. I plugged it in over night and now I'm almost certain my block heater is broken because nothing has changed, crawled under and nothing was warm, no snow melting anywhere, etc. I had the correct amount of PS winterized antigel stuff in the tank, but now either the lines are gelled anyways or i have an air leak in the fuel line somewhere. I'v had a good bit of priming issues recently but never to this extent. I replaced the fuel filter, wif sensor, and filled it with fuel and a little PS, but it still won't prime. The primer will not get hard ever, and no fuel comes out of the bleeder screw when its open, even with the newly replaced filter with fresh diesel in it. I greased all around the priming pump hoping to seal any air leaks, but nothing helped. When i press the primer i can hear air come out, but when it releases back up i hear air going back in which I haven't had happen before. Im at a loss here, Idk what to do at this point to get it to prime, so hopefully someone can chime in with some advice.
