Engine Mechanical problem
1997 Chevy Silverado V8 Four Wheel Drive Automatic 109000 miles
I just rebuilt a 1997 Chevy 7.4L 454 Vortec and when I placed it back in the truck I was unable to start the truck. It ran when I pulled it out, it had a spun bearing. I noticed that when I turned the key that I don’t get any response on the dash board other than the light indicator for the automatic transmission gear. The check engine light does not come on and the gauges don’t move.
I used my ODB II Scanner and there are no codes, however when I check the “I/M" status I get O2S Not RDY, HO2S Not RDY, and EGR Not RDY.
I verified that I have 12Volts to the Fuse Panel next to the ECM. Traced every wire and found each wire connected. I did have to crimp a new ground connector near the lefts side of the water inlet on the intake.
I do have spark at the plugs, I also noticed that the tach nor any of the other guages appear to be working. I woudl think it aws the ECM causing the problem. However I had the truck running before I took it apart.
There is an aftermarket remote starter on the truck. Not sure if this woul dhave anything to do with it or not but nothing was touched other than pulling the engine for a rebuild.
I verified TDC today. I still think the root problem will be solved once I find what would cause the dash lights from coming on when the ignition is in the ON position. Does anyone know what would cause the lights and the guages not to respond when you turn the key on?
have the same problem?
