Is the anti-theft light lit on the instrument cluster ? Won't start how ? When you turn the key to start , what happens ? Nothing ? This would be a No crank - no start condition . Now if you turn the key to start and the starter engages and spins the engine and it doesn't start an run , this is a engine cranks no start condition ! Now which is your problem ?

There are two fuse's IGN A fuse 40amp and IGN E fuse 10amp ,both are located in the under hood fuse/relay box . Also there is starter relay located in the same under hood fuse /relay box . There also is a crank fuse 10amp in the under hood fuse box . Besides the fuse's and relay ,the ignition switch or the PNP - park neutral position switch could be bad . Testing the whole starter circuit should be done ! How to voltage drop test starter motor circuit

My H2 Hummer had a computet code P003 misfire on cylinder 3.I switched the spark plug wires around now Im getting a computer code P001 multiple misfires

check engine control fuse and then switch the coil packs around again. Rescan, and see what you get. Then switch to different coils again and rescan.
Mine was a combination of a blown engine control fuse and one bad coil.
My friend had the same, but it was 2 bad plugs and one bad coil.

Hummer H2 rear wiper and sprayer came on by itself

It sounds like the wiper control module. The wipers on my 2003 did the same thing. After I pulled the fuse for the rear wiper, the front wipers started acting up as well. I had to pull fuses to stop them too. There is a recall on 2003 H2's for this issue. The cover of the wiper module on 2003s for the allows rain/water to get into the module. The cover will be replaced for free, however, in my case since the module was full of water and my wipers were not working, they replaced the module for free also. Not sure how much it would cost to replace on a 2005.
