I have a p72 OBD1 gsr ecu. How do I check the code it is throwing? I know you stick something in somewhere and look for a light, but other than that I have no idea....

 

BLUE CONNECTOR BY PASSENGER KICK PANEL . PUT PAPERCLIP TO TWO TERMINALS AND TURN KEY TO POSITION 2 DO NOT START.

 

I dont understand that. Anyone else

 

lol some people....
here.

To check the code, Take off the passenger side kick panel and look above your ECU (the metal box). find the green rubber housing
with a blue connector (looks like the end of a telephone cord). Get a piece of wire like a paperclip, and
bridge both connections. Now turn your key just before you have to start the car, watch your CEL and get the code.
If the CEL blinks fast, that stands for 1, 2, 3, etc. If it is a long blink, that stands for 10, 20, etc. The code
will recycle, just in case you don't get it the first time. also, there could be multiple codes.

 

So you just hold the same paperclip to two seperate points?? This seems easy enough
