FUEL PUMP MAKES NOISE PRESSURE GAGE READS 40 PSI
Fuel pump is bad. At idle pressure should read 50 PSI. Replace with original manufacture fuel pump after market pumps will burn out fast and are unreliable from my experience. Also could have a bad fuel regulator but that only works while driving down the road full throttle. You can unhook the fuel rail pressure regulator and that will give it full fuel and the pressure reading should read 60 PSI while it is running. If you turn the engine off and turn the key to run position it should read 50 PSI and hold for 60 seconds, if it drops below 30 PSI after 30 seconds Pump is defective. Many pumps are going bad here of late as people have been running them less than ¼ tank and this kills the pump. The fuel cools and lubricates the pump so the lower the fuel level the worse it is on the pump below ¼ tank. Not to hard of a job to do if you want instructions let me know.

97 Lumina...Switch stuck on defrost vent and
I had same problem . There is a vacuum resovoir tank located behind the left front splash shield . The vacuum line behind the battery goes to it . I removed two 5/32 screws just in front of the tire that hold the splash shield to the fender , carefully flex the shield away from the fender and take a look . I found the vacuum line had come loose , plugged it back on and everything works . Hope this helps

I own a 1997 chevy lumina, when I turn the car off
it has command start ???? Is this some kind of aftermarket add on ? This shouldn't have anything to do with the running lamps . unless someone hooked something up in correctly . Does the car have DRL - day time running lamps ?
The Daytime Running Lamps (DRL) control module is designed to automatically operate exterior lights depending on outside light conditions.
The DRL control module operates in 2 modes:
• The day mode
In the day mode, the DRL control module turns ON the high beam headlamps at a reduced intensity when the DRL ambient light sensor detects daylight under the following conditions:
- The ignition switch is in the RUN position.
- The headlamps are OFF.
- The park brake is OFF (released).
• The low light mode
In the low light mode, the DRL ambient light sensor detects darkness, turning OFF the high beam headlamps and turning ON the low beam headlamps through circuit 10.
Additionally, the DRL ambient light sensor turns ON the following lamps through circuit 9:
- The park lamps
- The sidemarker lamps
- The license lamps
- The tail lamps

Pt 031 code cylinder1 misfire
plugs are seldom the fault
the injectors are generally the problem from dirt or wiring faults
run a quality injector cleaner
or take the car to an accredited service center for a proper diagnosis and quote
