Question about 2000 Chevrolet Impala
Lightening struck a tree next to my car and now it won't start. I changed the starter and the crank relay (I believe that is what its called) It is a 1 inch square fuse like block that goes in the fuse box under the hood. I had a mechanic inspect it and he checked and tested the car following the path it takes to crank the car. He said the computer ground is bad and the computer needs replacing. Could he be wrong? Can a used computer be installed or does it have to be a brand new one? He also said something about checking to see if the computer needed to be flashed or if it could just be installed. Can you advise me on this? I am a single mother on disability with very little money and no way to get a new car.
#1 If the starter relay is bypassed will the car start and run? Has the car enter anti-theft mode? a used computer can be installed and all computers need reprogram new/rebuilt/used. If car can start and run without relay then the "controlled wire " can be grounded without replacing computer if NO other issues exist.
#2 scan tool check for codes in the IPC system this is where anti-theft information is stored.

you are on a search and destroy mission, i recommend you buy a manual with wiring diagram, at least it will tell you what is hooked on that circuit, thenits a matter of testing wiring, i suspect you have a short somewhere

Testimonial: "Well, thanks for the opinion, even though I read it after fixing my problem. It was indeed a short, as the cover for the wiring harness was missing, and apparently a wire had rubbed bare and was shorting against the valve cover. I couldn't actually see the bad spot, but by carefully moving it I isolated the spot and taped it up really good and put a new cover in place. Thanks for the quick reply though!"
SOURCE: It is a 1997 Chevy
IF THE MOTOR WILL START WHEN YOU JUMP START, THE BATTERY IN THE BLAZER MUST BE LOW. USE A D.C. VOLTMETER, THE VOLTAGE AT THE BATTERY WITHOUT JUMPER CABLES, SHOULD NOT DROP BELOW 9 VOLTS WHEN THE STARTER IS TURNING. THERE IS A CRANK FUSE IN THE INTERIOR FUSEBOX. & A STARTER RELAY UNDER THE HOOD. BUT IF THE STARTER IS TURNING, THOSE ITEMS ARE WORKING. THEY ARE ONLY TO MAKE THE STARTER TURN. GOOD LUCK, DRVOLT.

Does the security light in the dash blink?
Thinking it's a pass code fault(ignition switch)
There is no chip in the key,the computer looks for the proper rotation of the switch,had the same thing happen,
Should be able to start it if you crank the engine for a few seconds,release the starter and DON"T turn the key off,wait 10 minutes,crank it again,should start.
If not do the procedure again(had to do it 3 times on mine)
This is the relearn procedure that also has to be run after the switch is replaced(with a new key also)
