What is the plug for on my fuel bowl

[erbilabuc]

I noticed a plug in the back of my fuel bowl because it wasnt plugged in. I plugged it in and now my truck wont start. What is this plug for?

i think it is for the heater in the bottom of the fuel bowl.

Fuel bowl heater, you probably blew a fuse when you hooked it back up. Unplug it and check your fuses.

yep heater in the fuel bowl. Its a common problem for it to have a short in it and will blow fuses. The easiest way to fix that problem is to just leave it unplugged.

Yeah Im just going to leave it unplugged. I dont understand though why it would cause the truck to not run when its plugged in but whatever.

being unplugged equals open circuit which is same as blown fuse. Its kind of backwards if you ask me.

The fuel bowl heaters will sometimes short out and blow the PCM fuse. If your heater was shorted, and that is why it was unplugged, when you plugged it in it would blow the pcm fuse again and cause the no-start. I dont rememeber the fuse number, but I think its 17 or 20 (I'm really not sure so dont quote me)

the bowl heater runs on the same fuse as the PCM...if the PCM has no power the truck cant run...we get 30 bellow 0 quite often up here..i have no fuel bowl...my spin on filter sits down on the frame rail and my truck has never gelled...leave it un plugged and forget about it...
