I have an LLY 2005 bone stock except 4" diamond eye exhaust. Different truck than my sig. My wife unplugged the block heater this morning and said she heard a pop and smelt something like an electrical burn. She started the truck truck in ran a few seconds then died. It will not restart. It cranks but does not start. Any suggestions?
Wont start after unplugging block heater
- Thread starter mechman3
- Start date
No I didnt. I didnt think that would have anything to do with an electrical issue. But I will try it when I get home Thanks
The starter is controller by the ECU, so if it is enabling the starter, the ECU is alive at least. Crank but no start can be caused by a ton of things, and really requires a scan tool to log rail pressure, RPM, etc. Given it was cold enough to need a block heater, it is possible the fuel gelled slightly, and it just needs primed and some additive.
If the block heater had shorted to something important, I would imagine it would have not started/cranked at all, but the fact that it initially fired is a good sign.

Thanks Dave that is encouraging. I was thinking the same thing.
Thanks Aweta I always forget fuses lol

Maybe I'm wrong but...doesn't the starter wire come from the ignition switch? I spliced into it wiring up my remote starter. It read like 14ohms to ground, so that makes me believe that's the starter solenoid?
On another note...maybe the fuel did gel up, and the popping noise was from unplugging the block heater? Mine will arc and pop pretty good when unplugging it.
I am guessing the popping was from her unplugging it. However if it were a wire related to the starter, I do not see how it would crank and turn the engine.
Start and run for a few seconds followed by a crank no start is almost always a loss of prime situation in my experience. I wouldn't let the block heater thing throw you off too much. It may have been nothing.
Yeah block heater pulls 1000w when you pull it apart almost always arcs. The plug gets kind of warm is that normal?
OK after depressing the prime button several times and cranking and doing this 3 times the truck finally fired right up. It didnt even dawn on me that the problems were not related. I had forgotten that just this past Saturday I had the oil changed AND the fuel filter. I drove 20 miles on Saturday the truck sat until Monday. My wife drove it for work all day Monday with no issues. She is a homecare nurse so alot of visits everyday starting and parking the truck. Then today truck wont start. LOL
Thank you to all who offered suggestions I appreciate this forum more than you know. I suppose alot of help from been there done thats helps all of us who dont know or forgot

May be time to rebuild or replace the fuel filter head, Saturday to Monday is not that long of a period for the truck top sit and lose prime.
So an update. I took it back this morning and the new fuel filter was seeping at the sensor on the bottom. Easy fix. they just were not thorough in the install.
Block heater wont cause a crank no start. Glad you figured it out. The 110v block heater plug goes straight to the passenger front freeze plug.
