Wont start

Wont crank in park. Will crank in neutral but wont start. Also I can move the gear shift without touching the brake. Also will not unlock locks when turning the key off. T his was the first thing I noticed after driving and stopping. Then it would not crank. It did start once in neutral then I turned it off and it cranked but wouldn't start. I tried a new ignition switch. Could this be the paddock or maybe the lock cylinder?

I tried the reset. My security indicator does not even come on during this process to turn itself back off. I checked all ignition fuses and even fuses. I am stranded and have no way to check fuel pressure. Truck will start with starter fluid. It seems my fuel has been blocked out. Is it possible the contact in the lock cylinder is bad and wont let the paddock reset.

What could be causing the other electrical issues I mentioned?

At first sometimes it would start and sometimes it would not and then nothing. It would crank but it would not start. I changed the fuel pump, fuel filter and fuel lines, and I just changed the camshaft positioning sensor and it still cranks without starting. If I use starting fluid it causes it to almost backfire. What else could it be?

Not to be a pain but what would cause it no to crank over in park but crank in neutral.

Did you get my last question?

Electrical problem
2003 Chevy Avalanche Four Wheel Drive Automatic 109, 00 miles

I just got this 2003 chevy avalanche from a dealership, I ran out of gas and put about 5 gals back into it and tried and start it. It wont start and it wont even turn over.

Nothing has been changed. Like I said this all happened at the same time very quickly after a long trip.

My Avalanche stalled at a red light, I tried to restart it but it will not do anything except sputter a little. I had the truck towed home and check the obvious problems. The seems to fuel at injectors. I traced the fuel line and found a check connection and there was fuel there. For the last several months it has been ideling at 500 RPM when stopped at a light and I have noticed the RPM wavering somewhat usually 100 - 200 RPM but it would always return to 500 RPM. I recently changed the fuel filter (last 6 months). When driving at highway speeds there is no loss of power.

I'm not getting fuel to the injectors, and after checking my pump there is no pressure or fuel. I am fairly well mechnically inclined so would changing the fuel pump something I could do in my drive? I'm assuming the tank is held on by two straps, not sure what happens when I drop the tank. Any hints on what to expect and what to watch out for?
