97 Bravada/ no ECM ign power
Been working on a 97 Olds Bravada that had stalling problems. No codes. Replaced bad fuel pump and got same results. Now the engine will crank, but I have no power to instrument cluster,mil etc. The windows lights and stuff like that work, but I checked for power at fuse box and found no power to the fuse ecm ign. I even replaced the pcm. Could it be a broken ground. Have power to pcm but not out.

Re: 97 Bravada/ no ECM ign power
Welcome to the Form. The trouble you just describbed sounds like the Ignition switch module (Black Box). in your steering column. Here is a link that can help you in replacing the switch. http://www.automotiveforums.com/vbul...gnition+switch

Re: 97 Bravada/ no ECM ign power
Hey Gabe, Ignition switch was the ticket. Really puzzled me when it was running then shut it off for a minute then absolutely nothing. I hate diagnosing electrical. Our shop is still running off of a brick. Customer and myself are satisfied. Thanks a bunch. Great forum here. Will be back more.
