Question about 2003 Chevrolet Impala

1 Answer

2003 Impala will start sometimes

My 2003 Impala has frequent problems starting. It will start then after several times it will not - the most recent favorite trick of the car, is NOT starting after fueling and still at the pump! Playing with the key switch will sometimes start it and jumping it will usually start every time. The battery and cables have been replaced since this has stared and connections rechecked. Is this a typical problem with this make of car?? Anyone have ideas about how to fix this - or even what the problem is?? I need to be able to tell a mechanic, and have a need to understand the issue. THANKS!!

It is possible that it's the ignition switch that's faulty, or one of the relays in the ignition circuit

My 2003 impala keeps cutting off and will not crank with the key everyone say it's the anti theaft system

It could be.

Put the key in the ignition and turn the ignition on/off several times. Then leave the key in with the ignition switched on for about 3-4 minutes. Then try and start the car.

Sometimes the system doesn't recognise the key.

Failing that, ask an auto electrician for an opinion.

1 Answer 2003 impala has a problem with not starting sometimes....just out of the blue it won't start......times vary before i get it to start again, from 10 minutes to 1 hour...the car isn't running...

If you are turning the key and it isn't turning over or anything and all the other electrical is working, there could be a problem with the ignition switch. But also if the theft system has been messed with, it's hard to tell what was messed up and mis-wired.

Tapping noise when car starts

Sounds like it could be your valves ticking. Sometimes this is caused by oil not getting to the hydraulic valve lifters for a couple seconds until the oil pump can get the oil pumped up to the top of the motor where the valves are. You might consider asking your mechanic to run a slightly thinner weight oil in your engine on your next oil change. Also, be sure to get frequent oil changes with new filter each time.

Hope that helps!

Might be the crank relay. Under hood passenger side lift plastic fuse panel cover using a screwdriver (or even just a carkey). $15 part. Sometimes it sticks. You can remove and tap it on the concrete sometimes to get you home.
