Is there a key light or light saying security flashing or illuminated at all when this happens you may need to reprogram your transponder in your key...putting some fuel directly in the throttle body without turning the key off after this happens and trying to start it back up would indicate if it starts again that you have a fuel issue most likely… if the computer doesn’t read the transponder in the key it’ll have similar symptoms have you run diagnostics since the condition had occurred
No key light and throwing a p1400 code cold start
CommentElectrical issues bad
Chevrolet Silverado 1500 2005 230000 miles
I have this issue. My cooling fans had gotten where they would stay running after I parked it and running my battery down . Then also my fuel pump stopped working and then started working again. But the fans come on when I turn the key off and turn off when I turn the key on. Now I have no power windows or locks only half of my instrument cluster works my abs and battery light and check engine all stay on . I have checked every fuse that I possibly know of I don't know what else to do?

No pwr No start. Fuse box? Etc
Chevrolet Silverado 1500 1998 159000 miles
I have 98 Chev 1500 4x4. I was trying to crank, would spin over but not crank, kinda like fuel pump bad. But spun over few times then no pwr. Like no battery pwr. Gauges didn't react when key turn to on position. Knew had bad starter also. So replaced starter, found body ground cable from hood to firewall broke and corroded. Replaced. But still no pwr. Checked fuse etc. Under hood.no blown fuses. Tried to find schematics for fuse box under hood but no success. Any tips on where I should start tracing wires etc or what I should check next? Any help greatly appreciated

Gas gage not reading right
Chevrolet Silverado 1500 2006 Lt, 6.0, 4x4, Vortex Max 199980 miles
After the dealership replaced the sending unit in the truck the gas gage started reading full or empty nothing in between and sometimes it will throw a check engine code. Would the be in the fuel pump or would that be a problem with the computer I’m really looking for a place to start. Is there a place that i could run a meter to see what the problem is before i start tarring into things?
