I have a 1997 GMC K2500 SLE with a Vortec 350 and a 4L80 automatic transmission. It has 140,500 miles on it. 14 bolt semi float for a rear end.

The truck will crank all day long but will not start. The idiot lights do not come on the dash and I can not hear the fuel pump buzzing. Everything else works (HVAC blower, lights, radio) except interior lights they never worked, except when you rock the dimmer switch.

I have checked all of the fuses and they are good.

I have 12.6 VDC running over to the power distribution block under the hood by the brakes.

I have all new connections on the battery cables.

Also I have just overhauled this motor about 500 miles ago and it has been running good up until now.

I don't know if this is related but I just filled up the tank.

I hope I have provided enough information.

THANK YOU GUYS FOR YOUR HELP.
