What is it on? Is this for a 1986 Buick Skylark?

rofl lmao!!!!!!!!!!!!!!!!!!!!!! NOW THAT WAS FUNNY!!!!!!!!!!!!!!!!!!!!:beer;

Ok, now that I am back in the saddle here is the info

20 Intake air pressure
Atmospheric pressure Defective values are detected due to the internal malfunction Fixes the intake air pressure and atmospheric pressure to 85.0 kPa. Able Able Dont worry about this code. It pops up every now and again.

It should be able to start with a code 20.

Do you know how to erase any stored codes so you can see what is actually trippin?

Hold the select and reset buttons down together. Turn the key on while holding them down. Release them both after a few seconds when you see "diag". Then push them both together for another 8 seconds until a large number comes up. Toggle through those numbers until you get to number 61. 61 tells you how many codes you have tripped and 60 tells you the actual code number. If you leave it on 60 it will cycle through any codes you have thrown. They stay stored in there so you need to clean em out to know what is trippin right now. After you do this try to fire it back up and then see what codes it spits out.


BUT before you do that tell me did you try to start it with the charger hooked to the battery when it stopped working??? If it wont fire when you turn it over you had to of blown your "Fuel Injection System Fuse". This is a 20 amp located just in front of the oil tank (not the big green one). Maybe you missed that one. It is the one on the right if you are standing looking at the oil tank. The one on the left is a spare. If it goes click, click, click when you turn it over then your main fuse (the big 40 amp green one is blown).

I know on the apex's if you have a fueling box and you get this code unplug the fueling box connector and plug it back into the stock harness, start it up and it should clear the code and go back to normal. Shut it off and hook it back up to your fuel box.

you all should really copy these!
