ordered the efan kit from pcmforless and got the loaner pcm. Unhooked the battery and installed it an rehooked the battery and it wouldnt remote start anymore. It acts like it wants to but when it goes to engage the starter it stops, does this 3 times then stops the cycle. Today installed my original pcm again along with the efan kit and same thing. With the loaner pcm i did have to do a security relearn, did not with mine. In the dash access panel is a gmbp passkey 3 & passlock 2 override interface module. I googled and found a manual for it showing how to reprogram it. Tried to set the jumper how it wants and the led wouldnt flash to confirm its been programmed. I think i might try to unplug the module then plug it back in and try to reprogram it. Anyone have experience with this? 2004 TB LS.
