There is a couple of problems with Impala's. Crank relay ($15) is unreliable. Lift hood it's on the passenger side under plastic panel and just plugs in. There are some issues with the pass code. Rather than take to a dealer, first place key in ignition and turn to the on position and wait 10 minutes. Often the pass code corrects. There are some issues with the ignition switch in particular with a heavy set of keys. Try blowing some compressed air into the keyhole and using just the ignition key by itself.

Call a Chevy dealership, ask for service department. Tell them about it and ask what you have to do to get the code. Also if it is n9ot a code then they may be able to help you out by giving you some suggestions, other than bringing it in to them.

Car won't start after putting gas in it kia 2003

I have seen this problem several times. The EVAP Purge Solenoid in the engine compartment is sticking open. When you refuel your vehicle, the open solenoid is allowing fumes from the fuel tank to flood the intake manifold with fumes. This is what is keeping your engine from starting...too much fuel and very little air. Most of the time your check engine light will also be coming on while you are driving your vehicle and the code that sets will say "P0441 Evaporative Emission System Incorrect Purge Flow" or there will be some other manufacturer-specific code or code description that will read something like "Purge Detected During Non-Purge" or "Purge Control Valve Stuck Open". However, I have also seen this happen without setting any codes at all (also see below). In each case that I have encountered, replacing the purge valve fixed the problem.

Also make sure your engine is turned off and the ignition switch is in the OFF or LOCK position when refueling. I have also seen this caused when somebody turns the engine off, then turns the ignition back to the ON position so passengers can "listen to the stereo" during the refueling process. This can cause the computer to open the purge valve during refueling. When it happens this way, there will be no fault codes stored and no repairs need to be made to the vehicle.

2003 chevy impala ls starts then stalls

I have replaced the radiator in my 2003 Chevrolet Impala LS. The car started running hot and shut down. Took it to a radiator shop and found a crack in the radiator. I have replaced 2 thermostats in the car already. I noticed water running from under my car today and it seems it was coming back out of the overflow. I am stumped as to what is going on with this car.
