Visiting my son-in-law in MI and he had this same problem. First he took it to a repair shop who "said" he put in a new ignition switch?? and charged $500!! Worked for a short time. Then when it recurred he bought a Newrockies. Didn't work so he returned it. Then I arrived and did the "re-learn" process several times which seemed to be taking, for a few hours!!! (next morning it wouldn't start again) So, I went to Radio Shack and spent ~ $4 for the 2200 ohm resistor pack and a European Style connector block for the by-pass trick. Again, seemed to work for only a few hours after re-learn. Then I found this post and the "Finally a cheap passlock fix" post and suspected the (new) ignition switch. So, I removed the black plastic cover over the contacts and voila, blackish contacts. Cleaned them with a screwdriver (ok, but even a q-tip or pencil eraser might have worked - I was too lazy to go get either). A few strokes and they were shiny. Car started perfectly every time since. Another post though said he had to it again in a year or so. Thanks EINst & jondoe28!!

 

Ok so this confuses me and I'm not sure what to do I have a 2001 Chevy Malibu and the car starts fine but the gauges don't like to register what should I do?

 

What happens if the PCM ACC fuse is burnt out?? What should I do
