1997 gmc sierra shuts off while driving

I've changed the fuel pump,filter, coil, modulator, but the vehicle still shut down after awhile, then after maybe 5-10 minutes it will start right up. the codes don't show anything wrong other than that she runs great the engine light is not on.

Had same problem with a Yukon. Turned out to be a bad fuel pump (Won't show codes.) When cold ran fine, heated up, no pressure. Would start after sitting for about 1/2 hour. When engine dies on you check for fuel pressure under the hood.

You might check for a fuel shut off valve. Some vehicles have them in case of an accident, it turns off the fuel pump. Some are just a relay that can be reset.

1993 gmc sierra k1500 5.7 V8, fuel system shuts down while driving. Have replaced fuel pump, fuel filter and fuel relay.


Check to make sure oil pressure switch is not sticking or gummed up and connections are tight. Your oil pressure switch is also a safety feature that will shut down fuel pump in case you're in an accident and/or rollover.

97 gmc sierra shut off well driving and wont start anymore but it turns over?


I really dont think its the ignition module.Those are a little expensive so i wouldnt buy one until you sure thats the problem.I would turn the key to the on position and listen for the fuel pump.The pump only runs for about 3-5 secs when you first do it.If you dont hear anything thats the ploblem.If you can hear the pump come on try to use starting fluid to get it started.If it starts and runs fine then the fuel pump doesnt put out enough pressure to start the truck and need to be replaced.If that doesn t work take a spark plug out of the motor and plug it back into the wire.When you try to start the truck it should make a bright blue spark.If the spark is not bright and fast it could be many things like that plug or that wire all the plugs and wires or the distibutor cap or the rotor.It could also be the coil.If you have the money you should replace all of that stuff.If your on a budget like me I would change the distibutor cap and rotor and see if that help.If the plugs and wires are fairly new change the coil.You should do your plugs and wires after so many mile or time period.Im sure its not the Ignition control module.The guy at the part store always says that might be the problem and ive never bought one yet.My truck has 250,000 miles on it and still going.

Is there an inline fuel filter in a 1997 gmc 2500 sierra truck wi


On the drivers side frame rail (inside) is your fuel filter. Cheap to replace. But if you don't hear the pump cycling prior to attempting start it is more than likely pump in the tank. Check fuses first though. Big job
