Hello I have a 2000 Toyota Camry LE with the 2.2L 4 cylinder with roughly a 180000 miles that I brought from a independent mechanic saying he rebuilt the engine with new piston rings a new cooling system since he "said" the car previously was overheating. I've owned the car for over a year and a half and have dealt with numerous issues with the car from leaking oil gaskets, to installing the correct spark plugs or OEM parts to fixing repairs that were poorly done or used cheap aftermarket parts that did not work in the long run. Then to find out that this mechanic was not truthful to his work or the repairs he did do which was little or did a sloppy job at repairing or was not fixed. I eventually took it to my trusted mechanic 2 Months ago due to the oil pump gasket was leaking, he found out when he took the timing belt cover off that the cover was in poor shape as in the previous mechanic tried to glue it on and had incorrect screw sizes and looked to be like it was broken off. My mechanic diagnosed that the water pump was starting to go out the oil pump gasket was never replaced and the timing belt was over 10 years old and was stretched. He got a timing belt kit and replaced everything and once it was all back together The Car Will Not Start. My mechanic said that it has no spark and he double checked to made sure the timing was correct he has then replaced both cam and crank sensors since they looked like they were damaged from being hit by something he got the computer checked to make sure that was good and also called in a Toyota specialists to check the car with his fancy Toyota scan tool and is not throwing any trouble codes and cannot find out why it will not start. Next week he is looking to change out the coil packs to see if that will fix it, but I am starting to wonder if I should keep the car after its fixed Because I don't want to keep it if more issues keep coming up but I do like the car, I didn't pay much for it, my mechanic says the engine and transmissions is good, and it does not overheat at all since I bought it, and I plan to replace the rear struts when I get it back.

To summarize it up what should I do with the car and as well as what causing the car to crank but not start with no Spark and if its worth keeping it once it is repaired because I still have faith that once these repairs are done it will be what a Camry should.
