Hi everyone!

Today i got some information from my electrician (who was checking my car for a sparking problem refer: https://www.thirdgen.org/forums/elec...park-help.html)

He told me that the security light is blocking my car starting. When i bought my car, i didn't get any keys with it. It was customized with a push to start button. You had to only turn the ignition (without the key) and press a button next to it to start. Interesting concept (i dont like it, i have a plan of removing it), but the god damn car doesnt start anymore. It was fine for 5 months and suddenly the security light started working.

What am i supposed to do? Help? I am totally clueless and the electrician as well.

 

I found this document.

With passkey 3, where do i get this master key?

 

That document is useless to you , except for showing you pretty pictures of keys . You do not have the "passkey 3" system , you have VATS . Your ECM has no "relearn" feature for the antitheft system , it's either getting it's proper VATS enable signal from the VATS module or it isn't , and from the sounds of things with the security light on , the ECM is not getting it's enable signal from the VATS module . In our third gens you could take a different ECM from a different 1989 2.8 six MPFI VIN S 5 speed car and it would accept the signal from your VATS module just fine with no relearn needed , the only two "matching" parts being the resistor in the key and the VATS module itself .

BTW , VATS does NOT kill the spark in our cars ! It kills the starter crank signal and the injector spray signal only . If you have no spark , you have other things besides VATS to deal with , of course with the light on you now DO have VATS to deal with as well . Did this "electrician" disconnect something in his troubleshooting that may have affected VATS and put the light on ? Bottom line here is , unless this guy has worked on VATS equipped cars before , the learning curve could get rather costly for you as you pay him to learn about VATS . Now if someone in the past did the "VATS resistor bypass" to make the whole keyless pushbutton start thing happen and it worked for 5 months , your best bet is going to be to search out wiring diagrams and parts locations for the various VATS components and educate your electrician as to the system's proper functioning if effective repairs are to be made .

I wish you luck
