Driving home from work and truck cut off suddenly...would turn over but would not start. Towed home and here's what we've done so far. Replaced cap, rotor, wires, pick-up, coil, plugs, ECU, timing chain/gears, temp sensors. Checked fuel pressure, compression, injectors, MAP sensor, relays. The truck will crank but sputters and when you press the accelerator it takes awhile to rev up and acts like it has no power. Motor is 3.9 V-6...Please help...

 

I have a 97 dodge ram that the tail light and tags lights won't work.
