96 Dodge Caravan - no power

[mcarav]

Hi. I have a Dodge Grand Caravan 96 3.3l. I had some transmission problems and replaced the transmission. We didn't really need the caravan so fixing it got left to a side. It's been 5 months since it was last driven. In the meanwhile I replaced the transmission.


Now, I am getting several codes:

P0108 - Manifold absolute pressure/ barometric pressure circuit high input
P0118 - Engine coolant temp circ. high input
P0340 - Camshaft position sensory circuit malfunction
or
- No CAM signal at PCM
P0443 - Evap. emission control sist purge control valve circ malfunction

On a side, the engine starts but the car does not move. The wheels move when they are up in the air. In reverse they actualy do not work at all. Also, it backfires a lot.

Now I know that 1 problem can set up more codes. What can be the problem and how do I fix it?

Thank you, Alex
