Top 20 1996 Chevrolet Impala SS Questions & Answers

Question edited for a lot more clarity. Question moved to model category. It is easy enough to pull a plug and check for a spark. The problem is bound to be the CDI Ignition upgrade. https://www.google.com/search?q=Digital+6+plus+MSD+box ..

Get it scanned again. If you bought cheaper ones at the parts store instead of oem ones from the dealer you are probably going to be doing them again. The upstream and down stream 02 sensors communicate with each other so it could be the upstream sensors even though it says downstream. I ran into this problem myself.

Try spraying some WD40 inside the mechanism. Drown the thing in it. It won't hurt it at all. Wipe off the excess and exercise it to free it up. Should do the trick.

you have a short in wiring or a grounded out component check the door switch that usually gets chaffed from the door opening closing

Usually when that is case you need to look for a dimmer roller which is usually to the left of the steering wheel. If it was rolled all the way beyond the brightest setting it turns the interior lights on regardless of whether the car is on or not

if you are talking about the theft deterrent relay, It is wired between the ignition and the starter check to the right of your glove box, you will have to remove the lower dashboard and lay down so that you can see under the dashboard and you should be looking toward the rear of the car. It will be attached to the metal part of the dashboard. If you are looking for the actual theft deterrent module, look under the dash on the driver's side. look up and look for a black cover plate. unscrew it and the module is there.

The PCM is located directly underneath the air cleaner assembly (were the air filter is housed.) I have a 96 impala too. Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/genevieve_722d20889b4b9c97

You will need to adequately describe your problem to get a reasonable response. Detail the problem you're having in-depth.

sounds like an electric issue--the weakest link--chec all wiring for corrosion and gud contact--w old car may b relay--module--coil--ignition problems at distributr--make sure batt is 12.6v and cables are tite--a bad ground -short or open mite be too--along w igntion switch and on n on--getta haynes manual at partsplace for troublshoot details

Check to make sure that the battery is not defective. 12.5 volts . Make sure your connections are clean and tight, but do not over tighten or you may strip out the battery terminal, and then you will have to purchase a new battery. Check your fuses in the engine compartment either on the fender or the firewall. If everything checks out then check the connection to the started make sure you are getting power down there. 12.5 off battery lead. If all else has checked out okay, then i can only assume that the solenoid to the starter has gone bad, either replace it or more importantly replace the entire starter. To eliminate future problems from reoccurring

Make sure + and - leads are connected to correct terminals on battery; double check around battery to make sure you didn't leave anything hanging loose/unconnected.

Not by default.

I would start with checking the fuse and relay for that circuit. If that is fine then you will want to check the oil sending unit. If the sending unit breaks, the fuel pump will not work. Please state as much information as you can. Please write back with everything that you have tested and noticed. I will do my best to help. good luck.

The rear defro does not have power going to it with the key off. This means there is somehow a short to power to this switch, if you can remove the switch check for power at the connection. If there is power there is a short, I will send you a schematic of the circuit.

its In the fuse box ether under the hood or under or under the back seat follow the diagram in the box to find the relays spot you could take the same one from a another fuse to check if its good just make shure its the same and its not one you will need to check the problem

Possibly the head gasket was just hanging in there, and suddenly let go. or.... Maybe the cylinder head, or engine block, cracked (which would show up suddenly).

check for a loose wire or a bad resistor.

faulty heater resistor

more than likely if it does not have groves it is the idler pulley or the tensioner pully!! hope this helps!!

You'll need to get a new key made before that one fails. The locksmith will need to be able to read the chip to get the right blank.
