2002 Chevy Tahoe V8 Four Wheel Drive Automatic

I'm working on my 02 tahoe(not flex fuel) and got the following codes from the ecm: Too lean left and right bank, multiple misfires. When it's cold out, the vehicle will rev very high (approx 2k rpm) then drop down in idle and sputter. Since it has distributor-less ignition, should I be looking at the fuel pump, ecm, or harness? It should be noted that the relay for the fuel pump gets pretty hot when running.

What is the fuel pressure? Check the coil packs and check the spark plus wires. If you find any ignition part to be faulty, make sure you replace it with A/C Delco parts only....I am not promoting A/C Delco, but these ignition systems are specificaly designed for them.
