Question about 1994 Oldsmobile 88
Had a question for you, with the pass key systems used on the gm, I came across a thought and found some information about it. There have been cases where the wires that run from the controller that is behind the glove box to the key switch can break open causing a no/ intermittent start or loss of the fuel injector signal. I did check the signal, tossed the column up and down steer left to right ect, found no change at a constant 5volts. Wondering if you ever had this problem. I will go "ground hunting" and see what I come up with. Although I do have a person interested in the car and a did state there is a problem, still want it so maybe ill let it die. Although now, i really want to find out the problem. Thanks again.
Sorry so long to get back to ya..yes i have a lot of expierence in these. there several ways to fix it. 1st and hardest- thw wires that go bad are two white wires right behind the ignition lock cylinder itself. to repair it correctly you must disassemble the steering collumn and remove/replace the ignition CYLINDER with the pass key wiring attatched to it. 2nd you can bypass the cylinder if ya want to do it that way. check the resistance of the key on the pellet(black bump on the shaft), write the resistance down. go to the bottom of the steering collumn and find the two white wires wich sometimes have a third wire being a gound loop/shield. find the two wires in question by inserting the key into the ign. and matching the resistance of the key on two of these wires. should be the outside wires if a three wire set up.
cut the wires once you have found the wires for sure. go to radioshack and get an assortment of resistors. you need to match the resistance of the key with a combination of resistors that match the key resistance. Take your time to watch the scale on the meter wether it is reading k-1000= ohms or whole ohms. solder the resistors together and solder them inline with the two wires going to the theft deturant module and wha laa youv'e bypassed the ignition. 3rd- if you want to bypass the system all together then you have to pick up a 60hz generator and wire it onto the ecm. i can get you the pin# and generator info if ya need. i am not on here everyday so give me a little time to respond. good luck- you know where to find me ..scott
