DEAD -NEED HELP!

Dodge Ram

I've got a '89 Power Ram (4x4) with a 318 & auto trans. 104,300 miles. The problem I'm having is this; every time I try to start it the engine there is no fuel delivery to the throttle body. The idle speed motor isn't even functioning. Both of the fuel injectors aren't firing either, and I have no spark. The entire engine is dead. I've checked and the engine has a good ground(s).
The list of parts that have been replaced in the last 6 months right down to today are: fuel pump, fuel pump relay(ASD relay), fuel regulator, fuel filter, idle speed motor, throttle position sensor, map sensor, plugs, wires, cap & rotor, ing. Coil, dist. Pick-up, water pump & hoses(don't think that matters!) Also, I just rebuilt the throttle body the other day. I should note that I also just replaced; the valve cover gaskets, intake manifold gaskets, and all throttle body gaskets (along with the rebuild). I was very diligent about labeling everything I had to dismantle to remove the valve covers and the intake. I reconnected all electrical plugs, hooked up all vacuum hoses, and put everything back the way I found it. The only thing I didn't do was reinstall the air pump because I think the bearings are shot in it. I do have the fuel hoses hooked up right, I manually actuated my old pump relay to check that. Also, the fuel pressure is great.I've tried everything I can think of to fix this. I even unplugged all the connectors to the engine control box (behind the battery) and cleaned them thoroughly. All fuses are good, checked them for continuity. And I've checked all the fusible links on the drivers side of the engine bay. I don't know if it makes any difference but before it quit, I was only able to start it (it would start hard but idle fine) and only move it 8-12 feet in drive or reverse before it would stall, then I'd really have a hard time starting it. Giving it more or less gas pedal had no effect on it, it just moved so far and quit. Now that I think about it, it was getting harder and harder to start the truck for some time, right up to when it quit. As of 3/24/06 I just replaced the engine control computer, but the truck is still dead, the " check engine" light doesn't even come on. The computer is getting power though. But its still the same as before. Any ideas or advice that anyone could give me will definitely be appreciated.

Man thats alot of money you spent you can buy a new truck for that. Just jokeing. Replace your engine coil to see if that works.

Among other things, I did replace the ignition coil. Everything on or around the engine was replaced. Nothing is getting power from the computer, though the computer itself has power. Wonder if something is telling the ASD relay not to pick-up?
