Sounds like your fuel pump may have went out. Check to see if your getting fuel from the lines.

Look like the fuel pump is fine. I knew that because I turn the key to on and I head noise from the fuel tank, I removed 1 injector, lot of gas come out. It seems like something is turn off the PCM, so the PCM can't drive the injectors or the ignition coil.
I got 5V sensing from Crankshaft and Camshaft, measured near the connectors behind the engine.

Whens the last time you have replaced your cap and rotor/ plug wires?

thanks for your help 93Dakota,
I just did a major tuned up about 2 months ago( replace plugs, wires set, rotor, cap, and changed oil, water.....etc). The truck ran fine since then. Now, it doesn't run.

Check your ASD (Auto ShutDown) relay. IIRC, it kills the ignition and fuel pump. It may be sticking. A Chilton manual can show you where it is.

Thank you all for helping.
I pull out the ASD relay and manually check it, it work fine.
Here is what I know about the truck right now: When I turn the key to run, I heard clicking noise from the hood(sound like the ASD relay make contact, in about a couple second the relays open by itself. At the same time, I heard noise from fuel tank, so the fuel pump should be working fine too. It seems like the PCM is missing a sensing signal from somewhere, it can't drive the ignition coil and injectors.
I am having headache just to think about my truck.
again, thanks to you all
