Car stopped running would not start timing belt shredded when changing belt lined crankshaft timing went to do camshaft and can only turn about 1/8th of a rotation

I had to make a long trip with my vehicle and it was a real torture. It was not able to climb slopes, stalled every now and then, jerked and even consumed way too much fuel. The IAC valve, coil, spark plugs and its wiring and both the crankshaft and camshaft sensors had previously been replaced. All the new pieces were original ones, so the mechanic did not understand what was happening. After that, I asked him to show me all the vehicle's contacts, bought an electrical contact cleaner and proceded to clean one by one. Since then, the car has been working without any problems.

I bought the car after it has been sitting for a year. Put a new ignition coil and battery and it started right up. Ran ok for a couple days. Now it won't start. I put new plugs and wires, cam shaft and crank shaft sensors, fuel filter and fuel pump. I don't hear the fuel pump engaging and I have check all fuses. I am at a loss, any ideas would be appreciated.
