My 1998 neon has spark and fuel.The compression is good so I would say the timing belt is intact however it will not start..Anyone have an idea what it might be?

I would double check the spark and good fuel psi.....Ive ran a 96 neon with a nickle size hole in a piston for 100's of miles.....It just wouldnt die !!!! I put a used salvage yard piston in it and 75K more miles on it before i sold it. Great little cars.
If you are shure you have good fuel psi and spark, you might want to look at what the ecm is doing.

I got 4 codes..p0300 p0301 p0304 and p0140..The 300 codes are cylinder misfires..I am not sure what the 140 code is

Check wiring going to the crank sensor. They are bad about the wiring getting burnt up over time. Also the cam sensors are usually good for about 100k and then they are done.
