Chevy Blazer 1993 S-10
I've noticed when trying to start my truck, it takes several attempts to get the truck started. Once started, it runs rough. I've taken to a mechanic who says it could be the computer in the vehicle.

MasterI would find another shop ASAP. There is proper way to determine why your Blazer won't start and run correctly and guessing that it is the computer with out doing a thorough inspection and data scan is not the correct approach.
A code 34 is a Mass Air flow sensor code, which can/will cause a no start. If the wiring is broken, the sensor could be fine, but the computer does not see the signal. I can go through the other codes as well. I used to be a diagnostic tech at a GM dealer and I am not convinced by your mechanics explantions. Go to the basics, is it getting spark or fuel yes or no, go from there. I would find another shop.

The mechanic performed a complete tune up, changed the electrical wires, and pulled codes 23,32, and 34. He checked each sensor and found the sensors to be good. However, the car now will not start at all.
