Electrical problem
2003 Chevy Tahoe V8 Two Wheel Drive Automatic

Tahoe was running fine then suddendly died several times and wouldnt start back. Have checked the fuel pump and fuel rails both pressures are good. I have a new battery and its fully charged. What I did find is that I have fire to the spark plugs wires on one side of the engine but not the other. I dont know where to check next chankshaft/camshaft senors, ignition system, pcm. Any help would be appreciated.

No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it

My Tahoe would run fine and when I would cut it off it would not crank back. I had fuel and fire on one side of the engine. I could never figure it out so I took it to my mech. It ended up being the computer connection needed to be cleaned. I had replaced sensors, injectors, pulgs, wires, another words I spent alot of money on this thing and it was like I said the computer connection needing to be cleaned.
