2002 Chevy Silverado won't stay running
It started running bad ( cutting out while driving,
idling rough) finally died and would not start again.
I have replaced crank sensor pick up coil, ECM,
ignition module everything I can think of...it has
spark and fuel pressure
Water in gas.this time of year.pour dry gas a full tank oh high octane gas
Check for codes, you may have a plugged catalytic converter
Carb filter. Dry gas. Then high octane gas.few drop down the carb
Fan in heater under dash
Carb filter. High ocrane gas
After taking to Chevy place to have knew computer programmed I am now getting a u8100 code and my brake and abs light is on. Was running for a day then completely stopped again.
Replaced catalytic converter
Are you sure of that code U8100 and not u1800?
Yes accident sorry...typing for my husband while he is under the hood
You need to go back to the shop that programmed the computer cause that code is for diesel engines, It's looking for an FICM (Fuel Injector Control Module) which your truck does not have
It was the Chevy dealership
Let them know
Sorry U1000 code
Ok that sounds more related to your truck. U1000 is no communication between PCM (main computer) to BCM (Body control Module) Check for loose or corroded ground connectors there's a green wire between the 2 that I read it goes bad. If not you need to have the BCM checked
Could a bad BCM stop it from firing and and stop the fuel pump relay from priming
Pulled wiring harnesses yesterday someone had pinched wires between transmission, replaced those wires it started working. I would crank it then I would give it gas, it would die. Now it ain't firing at all. I'm at a loss and in usually a pretty good diagnostic guy.
