i am trying to pull codes from my car that i just converted to obd1 for my gsr swap, my swap is going shitty lol.

i need to pull some codes from the ecu so ican see what is wrong, i follow other instructions but i do not have that blue jumper in my kickpanel, probably cuz my car is pre-obd.

Any way to pull codes from a p28 that is swapped into a 91 integ? let me know Thanks!

 

try using a obd1 p72......my brother has a p28 and **** throws a hand full of codes....went to a p72 and car ran better..no codes....i would only use a p28 if my car was more heavily modified.

 

well,, that is the problem, i need to pull codes from my p28, i dont know how lol since there isnt a blue jumper, i just want to know how to get the codes since there is no blue jumper to short.
