Truck wont start
Well, looking for some help guys! Its 8 deg. this morning and my trunk wouldn't start. I had it plugged in I put in about 15 gallons of #1 a couple days ago cuz it was real cold, so I know I'm not gelled, I have just in the last couple months replaced batteries and altenator, so they are good, and I had gotten a new glow plug relay because I had a tough time getting it started last year and was told that was probably the problem. But it has always started fine *** long as it was plugged in, no today it would crank fine and there was white smoke coming from the exhaust and it was wheezing and burpoing like it wanted to start but wouldn't, sooo at 4:00 this morning thinking well my dumb a$$ is going to replace the relay now that its friggen cold out and off we will go! NOPE still just cough n weez n burp and smoke but no rattle rattle! Got any pointers? do I have glow plugs out? I was dold they hardly ever go out, kinda lost, can I either it should it start then? I had to hitch a ride to work so I cant check till I get home.
