wayno Posted May 1, 2014 Report Share Posted May 1, 2014 It's likely the fuse block, mine did the same thing, and it was the fuse block, heater fan stayed on also. Quote Link to comment

EastBay521 Posted May 1, 2014 Report Share Posted May 1, 2014 alternator has been replaced along with the engine.but its been doing it ever since he got the truck like 2 years now? Quote Link to comment
ggzilla Posted May 1, 2014 Report Share Posted May 1, 2014 Wrong alternator can cause the engine to keep running. Does the alternator have F N on the back, or L S ? Quote Link to comment
wayno Posted May 1, 2014 Report Share Posted May 1, 2014 Pull all the fuses, does it keep running? Quote Link to comment

banzai510(hainz) Posted May 1, 2014 Report Share Posted May 1, 2014 unplug the volt reg then sut off. Heard of bad volt reg but if wrong alternator that could be it also Yeallas if your alternator has the black cage in back then its the stock alternator and most likely the volt reg. get a solid state volt reg.
