my heater element finally broke loose after 129k. my truck would start and run for two or three seconds then die. question is... how does the pcm shut the truck down when fuse 22 is blown? the truck would start, so i don't think it shuts the fuel off? i'm sure someone here knows the answer. how about enlightening me.

Fuse 22 powers the PCM relay. no fuse -> no pcm.
