|replace the starter too ,and still have the same problem its hard to start it takes several
attempts until it starts checked all the grounds still have the same problem and it still does
a weird noise too under the dash.
|Getting confused on the starting problem. Is it
cranking normally? Does it crank too long?
|It's does it when you want to crank the car on the dash it shows the battery check the
engine and the security but it wont crank it will start after few attempts.
|Okay. If it cranks but won't start then sounds like you have a possible theft
or security system problem. If it takes a few turns of the key to get the
engine the crank, then this may be a problem in the ignition switch. This
switch may also give you of the other problems you're having with the noise
under the dash and the other lights. With the engine running, tap on the
head of the Key with a small hammer to see If you can get the engine to die
out or the lights to start flickering or any other odd electrical Issues
|i took the car to the mechanics they put it on the computer and it showed the negative
post loose stopped doing it for a while. They told me the security on the key might be the
problem change it to the spare key and it started. Again with the same symptoms again
you have too wait for a while until it crank over. Now on the dash it shows check engine
light stays on you think it might be the ignition switch or the body control module? I for got
to tell you also the car was on a fender bender on the left side but the air bags didn't pop
out on the hit can that be another problem?
|The security system on this car does not use a chip in the key, so
changing keys would not matter. Sounds like an ignition switch or
passlock cylinder-which is the key cylinder. Need to scan the
computer for the check engine light first.
|How do i repair a code P0420 on a 2002 Chevy Impala?
|P0420 is usually caused by a bad catalytic converter.
|CAR NOT STARTING FLICKERING LIGHTS HAD THE SAME PROBLEM WITH MY 2002
IMPALA. REPLACED STARTER, IGNITION, KEYS BLAH BLAH. FINALLY FOUND OUT IT
WAS THE BODY CONTROL MODULE. HAD IT RE-PROGRAMMED FOR ABOUT $200,
NO MORE PROBLEMS
|Passenger side air bag light stays on and there is this humming sound coming from under
the dash. This sound started when the light came on. Can not hear it until you reach
30mph. 2000 Chevy Impala V-6 3800.
