When you reach down by the brake master area you will feel a wire and a 10 mm head bolt located on the back side of engine near the transmission. loosen the bolt with an extension then remove bolt sensor then carefully push the connector lock towards the end of the sensor to allow the connector to pull off. replace the crank position sensor to repair this issue.. the new sensor looks and fits different from the old one. as always check to see that the recall covering this repair has been done 1st. https://www.nissanusa.com/recalls-vin/
Hello Jk...If your Altima is a multi-coil pack set up, isolate the bad pack by checking with a volt meter for continuity from the primary to secondary leads or test the spark plug leads (with a grounded spark plug tester) at the spark plug boot end. The problem could originate from the coil(s) or the Ignition module or the PCM/EMC but start will the coil(s).
PS: Ignition system failures will not always be logged with fault codes as on board diagnostics are geared towards emission sensor issues.
1st and foremost run a OBD2 fault code test.

Check your exhaust system, some bolts used to loose or gone on Altima 02-06. Especially check the bolt close to the joint between exhaust manifold and front pipe. Check if your sway bar rubbing your exhaust pipe.

First of all, you'll have to clarify which belt it is you're talking about. Is it a SERPENTINE drive belt or a Timing belt? Two totally different belts.
If its a timing belt, you're in luck as Nissan Altimas have timing chains on the engines which shouldn't need replacing for at the very least 100,000 miles. If you're talking about the serpentine drive belt on the other hand, there's really only one way it can go over the pulleys. One side of the belt it grooved, and one side is smooth. There's only one way it can go over all of the pulleys while having the grooved face sitting on grooved pulley surfaces,... should be really easy to figure out.
