Are you following the process exactly right?

You want to take a paper clip and jumper the top 2 right pins together. Then, turn your key to "run" but do not start the car.
the CEL (check engine light) should blink once, and then twice which is code 12 or that it's in diag mode. It will do that 3 times and if there is another code, it will then flash the code such as blink 4 times and then 3 times. That is a code 43. it would do that 3 times. If there is another code it will then blink for that code. if there are no more codes, it will revert back to the 12 and blink that again
you then shut off the key, remove the paper clip and SEARCH for the codes as they have all been discussed many many many times on this as well as other sites. The newest 3rd gen is now 20 years old so feel confident that all the codes have been discussed exhaustively.

Re: cant pull codes
Might be a bad ecm. Go to pick a part and swap it out. How does it run?
