Would it be hard to change the belts on a 2000 dodge intrepid?

Our car was in the shop for repairs because it would crank but not start. The shop could not fix it. They said it was a computer problem and would have to be taken to a dealer for repairs. The dealer said it was the crankshaft position sensor, and that when they change it they have to change the sparkplugs at the same time. This would be $348.72 for the sensor and $149.95 for the plugs that includes a motor tuneup. Then, they said the belts have cracks, which would be $199.00, and a fuel system tuneup for $89.00.

My husband usually does work on our car, but he has been working alot of overtime, and doesn't have all the spare time to work on it. He would rather do without the charge for the belts and do them himself, but hasn't done that to an intrepid before. Does anyone know how hard it would be to replace the belts, to save us on the car repair bill?

Chrysler doesn't recommend 'fuel system tune up', except for a fuel filter change. $348.72 is a lot of money just to re -place the sensor. I would have them replace the sensor then drive it back home and do the rest myself.The belts ain't that hard to replace if you have any mechanical ability at all. The spark plug aren't to bad either, but if it's a 350 engine, the plug wires can be a real bear! Take it to the shop for those.
