2007 cheve tahoe 5.3 4x4 ls. Ecm issues suspected short to ground
@ScannerDanner hey Mr. Danner. I have a 07 tahoe with a very similar issue as this silverado. Its actually parked at the hilltop inn down the road from rosedale. Would it be possible for you to help me get wiring diagrams for this truck? I also use to be a student of yours in 2012 at rosedale. This is a friends truck. Been sitting a year. Hook up pos cable to batt. Fuel pump relay clicks 1000x a minute. And u can hear the fuel up act the same. With relay. Key now in and turned to on. Check engine light flickers with fuel pump relay. Really stumped. And willing to even bring it up to rosedale for content if your still up there. If anything i need a wiring diag
Wiring diagrams are very affordable now. You can buy access to the same Mitchell diagrams everyone uses for one vehicle via Mitchell DIY.
Are you certain the battery is fully charged and the terminals are making a good connection? This sounds like classic low voltage. Be it from voltage drop, poor grounding or a weak battery...
