99 escort died while driving threw cam pos sensor code changed sensor now no start

I was driving down the road. Stopped at 4 way,
went when my turn shifted into 2nd, shifted into
3rd, car died. Code reader returned three codes,
differential pressure sensor, o2 sensor and
camshaft position sensor. The first 2 codes it has
been throwing for months, I k ow I needed to fix
these thing but money is tight, after it died that
was the first time I ever had the camshaft position
sensor code. I changed out cam pos sensor and
still no start
