If I squirt a little starting fluid in the throttle body it starts up and continues to run just fine. I used a noid light set and I am not getting a flash at either injector connection. I have installed a new relay on the firewall and even checked the fuse (also on the firewall) with no correction of the problem. Is there any other fuses or relays I may be overlooking? ]]> GMC Sierra Forum tornadochaser69 http://gmcowners.com/gmc-forum/showthread.php?t=15536 http://gmcowners.com/gmc-forum/showthread.php?t=15535&goto=newpost Tue, 07 Sep 2010 03:03:35 GMT Yes I am sure it has one, I just forgot to ask and cant find where they hid it.

That night, he turned his lights on and the power to the CD player turned off. But no bigggy. A few days later, during the night, went for a drive and instead of the cd player turning off, it stayed on and smoke came from under the dash.

He stopped and we pulled the deck out. Found a bunch of cables melted together so I cut the Primary Battery and ground. Everything seemed OK on the drive home.. Except when he went to turn the truck off, now all the lights stay on even though the truck is turned off and the light switch is turned off.

Please help.
