yes you can clean the rotor, i agree with you there, but if he is going to be USING this truck, not just get it started for 5 minutes, then dropping 85 dollars on a tuneup is nothing.
changing the oil goes without saying. but it wont grenade the engine if you get it started.
And there is no such thing as a "vacuum sensor" that tells the computer if there is vacuum. There is however on some cars a MAP sensor. meaning manifold absolute pressure. This is what the computer uses to adjust the fuel and ignition timings by sensing manifold pressure. HOWEVER even a bad map sensor will not cause a car to completely not start, it would just run like crap. FURTHERMORE that part pictured is NOT a map sensor, and it is a not a "vacuum sensor"
*also, i suggested to replace those parts because it is inexpensive and you WILL end up replacing them later on. And since you have all those things out of the way. the only thing left to check for really would be a fuel flow problem. Leaky injectors. bad fuel pump, clogged fuel filter.
but like i said. Check the simple stuff first. Blown fuses, Make sure you can hear the fuel pump turning on, replace fuel filter.
